Submarine accidents which result in the submarine careening to the sea bottom are spectacular in Hollywood movies and video games, but they do not happen often in real life.  In fact, for the U.S., we have not lost a submarine to the depths since 1968 when USS Scorpion was lost with 99 souls due ( most likely) to an inadvertent activation of a battery or a torpedo.  Prior to that, in 1963, USS Thresher was lost with 129 souls due to ( most likely ) a piping failure during a deep dive.  Due to actions taken as a result of lessons learned from those two mishaps, the U.S. has not had a major submarine loss since then.  The safety record for U.S. Submarines since 1968 has been remarkable, and the envy of other countries.

Yeah, but what if?

To be prudent, the U.S. must assume that there will be submarine accidents in the future, even if they are not U.S. submarines.  For this reason, the U.S. continues to maintain a force dedicated to the rescue of downed submarines.  Undersea Rescue Command (URC) is the U.S. Navy’s official command for the rescue of sailors during a submarine casualty anywhere in the world.   If you would like to learn more about this command, you can read about it here.

The blog author has had some personal experience working with the Undersea Rescue Command, and all comments that follow are the authors personal opinions, and not an official opinion of the U.S. Navy or Applied Technology Institute.  In case you missed that, please go back and read it again.

Two significant issues that confront the Undersea Rescue Command are funding and localization. 

The funding issue arises from the fact that our submarines are so safe, and our safety record is so good, there is a hesitance to pay too much attention ( and funding ) to an organization which may not ever be called into service.  Unfortunately, there is not much the technical community can do about that; it will have to fall upon the Public Relations Office at U.S. Navy. 

Localization, however, is a problem which the technical community can help solve.  When a submarine goes to the bottom, the Undersea Rescue Command jumps into action, and reports to the vicinity of the accident very quickly.  Unfortunately, the Undersea Rescue Command cannot start their rescue mission until the precise location of the sunken submarine is known, and that is often a difficult problem.  Until the submarine is located, the rescue can not actually begin.  Often, in exercises, or in other countries, by the time the submarine is located, it has become a recovery mission rather than a rescue mission. 

So, how can we simplify the task of locating a downed submarine?  Some of the answer lies in the concept of operations, or things that a distressed submarine can do to facilitate the search for them.  Some of the answer lies in advances in sonars and sonar signal processing.  And the rest of the answer lies in innovative new ideas, for example, using AUVs or UUVs to find distressed submarines ( cool idea ). 

Applied Technology Institute is offering several courses in the coming months that will help you brush up on your skills, so that you can apply them to this problem.  You can find information about our Sonar Signal Processing course, and register for the course here.  Additionally, you can find information about our Passive and Active Acoustics Fundamentals course, and register for the course here.  Lastly, a full listing of ATI’s Acoustics and Sonar Engineering Courses ( including AUV and UUV courses ) can be found here.  If you are interested in a course which is not currently on the schedule, please let us know, so we can try to schedule an offering soon.

As I said earlier, the author has had the pleasure of working with the Undersea Rescue Command several years ago, and was very impressed with the hard work and dedication exhibited by all members of their team.  The following picture shows me and the rest of the JHU/APL Team that worked with the URC.  We are posing inside of the Pressurized Rescue Module which travels to the distressed submarine to perform the rescue.  Although no one would ever want to experience being on a submarine in distress, they should feel encouraged that a team as dedicated and qualified as URC is on the job.

Applied Technology Institute (ATI Courses) offers a variety of courses on space, communications, defense, sonar, radar, and signal processing. We believe the news summarized below would be of interest to our readers. February 16 marked the beginning of National Engineers week in the U.S.  EDN celebrated engineers with six reasons Why engineers are better than everyone else!  The tongue-in-cheek piece elaborated on these engineering qualities:
  • Team work, not cut-throat competition
  • You’re boring at parties
  • Start-ups don’t happen without you
  • Your degree is worth more than the paper it’s printed on
  • Go ahead, argue
  • Others make problems, engineers find solutions.
For the logic, see the entire article (Why engineers are better than everyone else) by Suzanne Deffree, February 20, 2014.

What You Really Need to Know About Unmanned Aircraft Systems (UAS)
Are you an engineer, aviation expert or project manager who wishes to enhance their understanding of the new and exciting field of Unmanned Aircraft Systems (UAS)? President Obama recently signed legislation that gives the FAA a deadline for authorizing the flying of Unmanned Aerial Vehicles (UAVs) in airspace now reserved for use by manned planes. The legislation requires the FAA to produce a comprehensive plan within nine months for integrating the unmanned planes into manned airspace. President Obama Signs FAA Bill into Law Large UAVs like the Predator and Global Hawk are always in the news and they can access Class A airspace (above 18,000 ft). Their long endurance and virtually unlimited range makes them ideal platforms for surveillance operations. They are routinely controlled halfway around the world using satellite links for beyond line-of-sight (BLOS) operations. Operational altitudes range for the smaller UAVs like the Scan Eagle are typically from 2,000-5,000 feet but flights up to 8,000 feet (6,000 at night) are common. Line-of-sight (LOS) range is about 50-100 miles when the ground is flat, or even less when hilly or mountainous. UAS technology has rapidly evolved in the military context to perform Intelligence, Surveillance and Reconnaissance (ISR) missions and provide the fullest possible understanding of the adversary to the commanding officer. UAV have the range and endurance to provide a bird’s-eye view of the battlefield and are flexible enough for dynamic mission re-tasking. This allows timely receipt of information about the adversary, when and where it is needed, without having to risk a manned aircraft. UAVs are often preferred for missions that are too “dull, dirty, or dangerous” for manned aircraft. Many of the military aircraft will be returning to the US for testing and training purposes and as the recent FAA legislation proves, there is a great deal of interest for civil use of UAS. Civilian UAVs have already demonstrated potential in a wide variety of missions. Local law enforcement, firefighting, agriculture, pipeline surveillance and atmospheric research are all areas which have benefited from UAVs.
One way or another, UAVs are coming to an airspace near you. Will you be ready for it?

ATI specializes in short course technical training
Our mission here at the Applied Technology Institute (ATI) is to provide expert training and the highest quality professional development in space, communications, defense, sonar, radar, and signal processing. We are not a one-size-fits-all educational facility. Our short classes include both introductory and advanced courses. ATI’s Top Five Engineering Courses for 2011 The five engineering courses for 2011 are highlighted below: #1 Practical Statistical Signal Processing – using MATLAB This 4-day course covers signal processing systems for radar, sonar, communications, speech, imaging and other applications based on state-of-the-art computer algorithms. These algorithms include important tasks such as data simulation, parameter estimation, filtering, interpolation, detection, spectral analysis, beamforming, classification, and tracking. Until now these algorithms could only be learned by reading the latest technical journals. This course will take the mystery out of these designs by introducing the algorithms with a minimum of mathematics and illustrating the key ideas via numerous examples using MATLAB. Designed for engineers, scientists, and other professionals who wish to study the practice of statistical signal processing without the headaches, this course will make extensive use of hands-on MATLAB implementations and demonstrations. Attendees will receive a suite of software source code and are encouraged to bring their own laptops to follow along with the demonstrations. Click here for the tutorial #2 Advanced Topics in Digital Signal Processing This four-day course is designed for communication systems engineers, programmers, implementers and managers who need to understand current practice and next generation DSP techniques for upcoming communication systems. DSP is more than mapping legacy analog designs to a DSP implementation. To avoid compromise solution appropriate for an earlier time period, we return to first principles to learn how to apply new technology capabilities to the design of next generation communication systems. Click here for the tutorial #3 Engineering Systems Modeling WithExcel/VBA This two-day course is for engineers, scientists, and others interested in developing custom engineering system models. Principles and practices are established for creating integrated models using Excel and its built-in programming environment, Visual Basic for Applications (VBA). Real-world techniques and tips not found in any other course, book, or other resource are revealed. Step-bystep implementation, instructor-led interactive examples, and integrated participant exercises solidify the concepts introduced. Application examples are demonstrated from the instructor’s experience in unmanned underwater vehicles, LEO spacecraft, cryogenic propulsion systems, aerospace & military power systems, avionics thermal management, and other projects. Click here for the tutorial #4 Wavelets: A Conceptual, Practical Approach Fast Fourier Transforms (FFT) are in wide use and work very well if your signal stays at a constant frequency (“stationary”). But if the signal could vary, have pulses, “blips” or any other kind of interesting behavior then you need Wavelets. Wavelets are remarkable tools that can stretch and move like an amoeba to find the hidden “events” and then simultaneously give you their location, frequency, and shape. Wavelet Transforms allow this and many other capabilities not possible with conventional methods like the FFT. This course is vastly different from traditional math-oriented Wavelet courses or books in that we use examples, figures, and computer demonstrations to show how to understand and work with Wavelets. This is a comprehensive, in-depth, up-to-date treatment of the subject, but from an intuitive, conceptual point of view. We do look at a few key equations from the traditional literature but only AFTER the concepts are demonstrated and understood. If desired, further study from scholarly texts and papers is then made much easier and more palatable when you already understand the fundamental equations and how they relate to the real world. Click here for the tutorial #5 Computational Electromagnetics This 3-day course teaches the basics of CEM with application examples. Fundamental concepts in the solution of EM radiation and scattering problems are presented. Emphasis is on applying computational methods to practical applications. You will develop a working knowledge of popular methods such as the FEM, MOM, FDTD, FIT, and TLM including asymptotic and hybrid methods. Students will then be able to identify the most relevant CEM method for various applications, avoid common user pitfalls, understand model validation and correctly interpret results. Students are encouraged to bring their laptop to work examples using the provided FEKO Lite code. You will learn the importance of model development and meshing, post- processing for scientific visualization and presentation of results.

Can You Afford NOT to Train when Technologies and Industries Change So Rapidly?
Are you or your team ready to face the challenges of tomorrow with what you know today? With technologies and industries shifting so quickly, businesses need to embrace training just to keep up. Some may complain that training is too expensive or fails to deliver its promise. But what is the real cost of slower sales and lower growth? Maybe you and your organization stop looking for perfect employees and start training them instead? As Wharton management Professor Peter Cappelli recently wrote in The Wall Street Journal: “Companies need to stop pinning so much of the blame on our nation’s education system. They need to drop the idea of finding perfect candidates and look for people who could do the job with a bit of training and practice.” We can help you. Why not take a short course? ATI short courses are less than a week long and are designed to help you keep your professional knowledge up-to-date. Our courses provide a practical overview of space and defense technologies which provide a strong foundation for understanding the issues that must be confronted in the use, regulation and development of complex systems. Since 1984, the Applied Technology Institute (ATI) has provided leading-edge public courses and onsite technical training to DoD and NASA personnel, as well as contractors. Whether you are a busy engineer, a technical expert or a project manager, you can enhance your understanding of complex systems in a short time. You will become aware of the basic vocabulary essential to interact meaningfully with your colleagues. If you or your team are in need of more technical training, then boost your career with the knowledge needed to provide better, faster, and cheaper solutions for sophisticated DoD and NASA systems.

Terry Dougherty wins Great American Teach-Off  for Her Work Tutoring Children of Military Families
Nominated by a local Rotary Club, Dougherty was one of top ten finalists left fighting for the prize. Hundreds of teachers from all over the country were nominated for this prestigious honor. Participants, families and friends were then all allowed to vote online for their favorite teachers, just like in American Idol. Each week, after all the votes were tallied, the two teachers with the lowest number of votes were eliminated from the contest. Jim Jenkins, President of the Applied Technology Institute (ATI), helped support Terry Dougherty for the award by forwarding the announcement of the contest to his instructors and people that he knows in the military. The people responded. From all over the world, all branches of the services, veteran organizations, service clubs etc., they responded. In what became a weekly ritual, they responded and voted for her. They keep voting, each and every week, until the end, until she won. The real winners in all of this are of course the children. Dougherty’s husband Tom started the tutoring program three years ago as a way to help children in need. Because military families relocate frequently, their children often suffer at school. The Seven Seals award is given through the U.S. Department of Defense to a civilian who is working to help military families. The award comes with a $10,000 grant. She will to use the grant money to purchase equipment for a mobile lab. The lab will allow parents stationed overseas participate in school activities.

This video of a 9 year old beluga whale seemingly dancing to some mariachi music has surfaced recently.  It was shot during a wedding ceremony that took place in Mystic Aquarium in Connecticut.   The whale seemed to bob his head and follow the rhythm of the music.  A lot of people would like to believe that this is exactly what the whale was doing.  However, scientific research shows that whales can’t hear the music the way we do.  They simply feel the vibrations.   But, that in itself, is a powerful gift. The underwater environment of the world’s oceans is filled with a variety of sounds.  Most aquatic animals use sound for communications between members of their species.  The reason for this is that sounds propagates well in water and covers longer distances.   Whales depend on sound vibration for orientation. This ability is important for predators of the deep sea where light is greatly reduced.  They use sound waves in echolocation and this allows them to detect objects and organisms by means of sonar.  Whales, as well as many other marine animals, use a form of song to communicate through the water. A whale will use their songs most often as mating calls for the opposite sex. You can listen to the marine sounds around the world on their site.  Please click on the link below.  This is quite a unique experience to be able to hear underwater sounds across the globe. http://www.listentothedeep.com/acoustics/index2.php?web=lidoearth&lang=en   If you wish to enhance your understanding of the underlying principles of underwater and engineering acoustics needed to evaluate the impact of anthropogenic noise on marine life, please attend ATI’s Underwater Acoustics for Biologists and Conservation Managers course that will be presented on October 17-20, 2011 in Seattle, WA.

The autonomous submarines at the Neutral Buoyancy Research Facility.

Nature shows and Caribbean vacation commercials often depict a school of fish moving as a single entity to avoid obstacles and elude prey. Engineers hope to give unmanned mini-submarines, mini-helicopters and other autonomous vehicles the same coordinated movement. Derek Paley, assistant professor of aerospace engineering at the University of Maryland’s A. James Clark School of Engineering, recently won a National Science Foundation Faculty Early Career Development (CAREER) Award for his proposal to study the coordinated movement of fish and apply it to unmanned submarines. Unmanned vehicles under multi-vehicle control could navigate more accurately and collect data more reliably than individual vehicles. The Navy plans to use a fleet of unmanned submarines to measure oceanic salinity, temperature and density—the factors that affect the speed of sound through water. These measurements, in turn, will help better predict sonar performance. Fish signal one another via visual cues and hydrodynamics (the movement of water). A line of tiny hair cells down each side of a fish helps them to sense the flow of the water around them. Paley is giving a fleet of mini-subs onboard cameras to mimic the visual sensing of fish. Also aboard each 3-foot-long sub is a tiny computer that can process the information from the cameras to determine the relative position of the subs around it and use this information to steer. Meanwhile, undergraduate student Alexander Leishman is developing sensors for Paley’s subs that will mimic the hair cells of the fish, to help the subs sense changes in the flow of the water. In lab space provided by biology professor Arthur Popper on the College Park campus, Paley has set up a network of cameras to monitor a school of giant danios (hardy freshwater fish about three inches long) and how they react when they are startled. When one or more fish in a school is startled, they trigger what is known as a “wave of agitation”—one fish takes evasive action, its immediate neighbors follow suit, followed by their neighbors, and so on. Paley takes the data captured by the cameras and uses it to create 3-d reconstructions of the fish movement. The models will help his research team better understand the information transmission among the fish and apply the same principles to the unmanned vehicles. “We’re developing modern engineering tools to quantitatively study this phenomenon,” Paley says. “We’re taking methods you learn as an engineering student and applying them to study biology.” The technology being built for the subs also can be applied to unmanned aerial vehicles. “We’re looking at planetary-scale applications for these vehicles; for instance, monitoring conditions inside hurricanes to improve forecasting models,” Paley said. “It’s important to fly lower—below 10,000 feet—to collect data where the air meets the water,” explains Paley. “Manned aircraft can’t fly that low inside a hurricane for safety reasons.” Paley directs the Collective Dynamics and Control Lab, where he supervises the research projects of twelve undergraduate engineering students who help him build the autonomous submarines. Paley also has six graduate students working on related research including Sachit Butail, a doctoral candidate who is developing an automatic tracking system to monitor the fish and produce data at an unprecedented rate and volume. This fall, Paley will add a neuroscience grad student to his team who will help design and conduct experiments to glean more from the communication behaviors of the fish.

Acoustical Society of America held 159th meeting on on noise and noise control at Baltimore Marriott Waterfront Hotel in Baltimore, MD on April 19-23, 2010. Lister below are just a few of the meeting’s many interesting noise-related talks. 1) Aviation Engineering: STIFLING THE SONIC BOOM 2) City Noise: IDENTIFYING THE SOUNDS OF CRISIS 3) Human Noises: SOUND LEVELS IN THE ARCTIC OCEAN 4) Community Noise Mitigation: PUBLIC OUTREACH WORKSHOP 5) Noise Inside a Car: QUIET CONCRETE ROADS 6) Construction Noise: “NO RACKET” JACKET FOR JACK HAMMER 7) Signal Processing: NOISE FILTERING FOR THE HEARING IMPAIRED 8) Noise in Healthcare Settings: NEW LEGAL STANDARDS 9) More Highlights — OTHER INTERESTING SESSIONS 10) More Information for Journalists ———————————————————- 1) Aviation Engineering: Stifling the Sonic Boom SONIC “PUFF” TECHNOLOGY MAY SPEED SUPERSONIC FLIGHT OVER LAND For the last 40 years, commercial aviation has hit a speed barrier in regulations prohibiting supersonic flight over land. These aim to limit the negative impact of loud sonic booms on populated areas, and current regulations permit commercial supersonic flight only over oceans, significantly limiting the speed benefit from supersonic flight. New aircraft configurations are emerging that are shaped to minimize the shock waves associated with sonic booms and may allow supersonic speed over land. Talk #1aNCa1, “Sonic boom: From bang to puff” is at 8:05 a.m. on Monday, April 19. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa53.html ———————————————————- 2) City Noise: Identifying the Sounds of Crisis ACOUSTIC AND SEISMIC SENSORS IN BALTIMORE HELP SORT COMPLEX CITY SOUNDS Beeping, shouting, construction, the sounds of tires on roads, and other loud noises — all partly masked by mazes of tall buildings — make up the fabric of the modern urban soundscape. To urban sound sleuths such as Donald G. Albert, a scientist with the Engineer Research and Development Center (ERDC) Cold Regions Research and Engineering Laboratory, in Hanover, NH, this complex soundscape is a challenge. He is tasked with developing a way to use sensors to sort out the complex bounce of signals, noise, scattered sounds, echoes, and vibrations in urban environments. Talk #1pNSc1, “Urban acoustic and seismic noise measurements in Baltimore” is at 1:30 p.m. on Monday, April 19. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa238.html ———————————————————- 3) Human Noises in the Arctic LOSS OF POLAR ICE INCREASES BOAT TRAFFIC AND SOUND LEVELS IN ARCTIC OCEAN With the melting of polar ice, never before in modern life has so much open ocean water been accessible in the Arctic. And where there’s water, there is opportunity for commercial shipping, and where shipping lanes emerge, big boats — and big noise — may follow. Talk #1aAO1, “The accessible Arctic Ocean” is at 9:05 a.m. on Monday, April 19. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa26.html ———————————————————- 4) Community Noise Mitigation: Public Outreach Workshop NOISE HAS A PROFOUND LOCAL IMPACT — EVEN IF FEDERAL POLICY DOES NOT Community noise is a major social problem that generally decreases the quality of life for many people in the United States, and it is continuing to grow — especially in major urban areas. In cities like Baltimore, community noise causes a variety of problems for local residents — from simple annoyances to profound negative impacts on human health. The workshop will include a panel of prominent national speakers on community noise control who will make presentations on a variety of topics faced by residents of Baltimore, including the noise situation in Baltimore, desired local government responses, the Baltimore noise ordinance, the Maryland noise control regulation, and the role of federal, state and local governments in addressing community noise issues. The Workshop will also give the first brief overview of a forthcoming National Academy of Engineering study titled “Technology for a Quieter America,” which will be published later this year. ———————————————————- 5) Noise Inside a Car QUIET CONCRETE PAVEMENT IS KEY TO MORE QUIET RIDE The stereo test tells all: You’re in the driver’s seat, buckled in, mirrors adjusted, traffic checked, in gear. Rolling. Cue the sound system, crank the volume, and crank it again. And then crank it again. This simple diagnostic is revealing: If you have to keep turning your stereo up as you drive to hear the music, you likely have “noisy pavement” under your tires. April 19. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa210.html ———————————————————- 6) Construction Noise QUIETING THE SOUNDS OF PROGRESS — THE “NO-RACKET JACKET” New York City is constantly maintaining, repairing, and reinventing itself, ongoing work that creates a lot of construction noise. However, a collaborative team including the New York City Department of Environmental Protection (DEP), consultants, utilities and an equipment vendor are working together to quiet the sounds of progress and improve the quality of life for those who live and work in the city. In furthering the city’s commitment to reducing noise is embodied in a new noise code and new construction rules, the DEP team wanted to look at ways to eliminate jackhammer noise — an annoyance for residents and businesses and an important occupational hazard for construction workers. Talk #2pNCa9, “Proactive regulation engenders creative innovation: Quieting the jack hammer” is at 3:00 p.m. on Tuesday, April 20. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa478.html ———————————————————- 7) Signal Processing: Noise Filtering for the Hearing Impaired A SOLUTION FOR IMPROVING SPEECH INTELLIGIBILITY FOR THE HEARING IMPAIRED Recall what it is like trying to focus on a conversation in a crowded and noisy bar — and then imagine having to do this even in a relatively quiet room. This is exactly the challenge that faces many people who rely on hearing aids or have cochlear implants. While these technological advances make it possible for many to hear who would not otherwise, they do not allow the individual to filter out background noise. Talk #2aSC1, “Noise-suppression algorithms for improved speech intelligibility by normal-hearing and cochlear implant listeners” is at 8:05 a.m. on Tuesday, April 20. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa410.html ———————————————————- 8) Noise in Healthcare Settings NEW ACOUSTICAL STANDARDS PRESENT BOTH CHALLENGES AND OPPORTUNITIES A pair of new documents on healthcare acoustics, which have just been released after five years of peer review and public comment, are described by one of their authors as both a carrot and a stick. They set measurable minimum acoustical standards for the health care industry, and because these new standards have already been adopted by the Leadership in Energy and Environmental Design (LEED) Green Building Rating system, they are the basis for two new Environmental Quality credits. Because of Health Insurance and Portability Act (HIPAA) rules and new conditions imposed last November by Obama’s ARRA HITECH Act, there are serious fines (up to $1.5 million) for non-compliance. Talk #2aNSc11, “Strengthening the healthcare guidelines: About the new online research community” is at 11:40 a.m. on Tuesday, April 20. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa369.html Talk #2pAAa1, “Speech privacy: The new 2010 architectural guidelines” is at 1:00 p.m. on Tuesday, April 20. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may10/asa438.html ———————————————————- 9) MORE HIGHLIGHTS — OTHER INTERESTING SESSIONS ON NOISE In addition to the highlighted talks above, there are many other interesting noise-related talks and sessions at the meeting — some of which are listed below. For a complete list of abstracts for any of these sessions, go to the searchable index for the 159th Meeting (http://asa.aip.org/asasearch.html) and enter the session number with asterisk (e.g., 1aNSa*).

Comments From Environmental Scientist On Reducing Low-Frequency Home Noise and Vibration

Well, we seemed to have hit a nerve with our series of posts on Reducing Low-Frequency Home Noise and Vibration:

The comment below came from a wonderful gentleman willing to help a fellow human being.

I am an environmental scientist, and have been involved in the wind energy industry where this is also an issue. The problem is uncommon, with less than 1% of the general population able to detect LFS (Low Freq sound – less than 20 Hz) dominated by people over the age of 50, and two thirds are women. So you are not imagining the issue, but keep in mind that it is unlikely that it is your ears that are detecting the sound, and that LFS behaves very differently than audible sound does.

I find your solution to be very innovative, and supported by some excellent work by a retired Univeristy Prof (Dr Barnes) in London, England. He obtained a microphone and laptop datalogger and wandered the city obtaining background readings. One of his more interesting observations was that background LFS declined after heavy trucks passed when near high traffic roads. This suggests that LFS can be neutralized by other LFS sound.

I am no sound expert, but this is the only solution I have ever read about. It is basically the “white noise” approach used for audible sound, but in that case the goal is to increase the individuals toleration for the sound (which is how white noise works, by raising our detection threshold) but rather to distrupt and decrease the level of LFS inside your house, by increasing the levels of LFS generated inside the house.

I know this sounds a bit out there, but read a few of the other accounts given on this page, for example the one where the hum returned after a new water heater was installed. The owner blamed the new water heater as the source, but it may very well have been that the old heater was “noisy” enough to have created the interference with the LFS. Getting the new heater to run better would of course just make the problem worse.

So I put this idea out there. If you can generate a background inaudible “sound” of less than 20 Hz inside your house, using the technique described above, and play it over and over, it could disrupt the LFS being generated by the house. This could require a specialized “woofer” type of a speaker. If anyone tries this, I would be very interested in the result.

Good Luck D
