More Information On Reducing Low-Frequency Home Noise and Vibration –

We received a question from a consumer regarding low-frequency home and vibration.

We received a question from a consumer regarding low-frequency home and vibration. After a response from expert staff of Acoustics and Noise instructors and a few additional posts on this general topic of interest, the response below came from the original consumer.

Dear Sir, Here is my reply. You asked for it, and it is lengthy. I am so grateful that you all are taking your time to give me your suggestions. I think a probable low frequency noise source, in addition to the trains, and obvious manufacturers’ noises, could be an asphalt batch plant that is located just behind our neighborhood. I drove by and listened and it is quite noisy with its clattering conveyer belts, giant blower, and the huge rotating mixing bin. I doubt we could have any influence on quieting such an operation. When we moved into our present house this plant was hidden by trees. Now that the leaves are gone, it is easily seen. Let the renter beware! We have tried all the things that were suggested in your e-mail. White noise machines and fans just added noise to the home and was not the solution I needed. The best brand of ear plugs worked well, but are kind of dangerous when you need to listen to what is going on in the house at night….like when someone might be sick and need help. ( mothers can appreciate this reason), or a tornado siren, etc. My husband must sleep and so I have the “night watch”. .The Bose headphones (thanks Grandma) did not do a thing for the low frequency, but one of my sons is enjoying them tremendously now for listening to music. I hate that she wasted so much money on something that didn’t work. I, too, have wasted lots of money buying several bundles of Fibrex to use as “bass traps” of sorts thinking that it might help. It did not. We did the realtor thing also. We moved from our first house recently. That house has its own story. We had moved to this town from out of state and did not know much about the area. Well, the house we bought was down the street from a gas well compressor. It was hidden in a wooded area and we did not know about it. Who would ever think that such a thing as a gas well compressor would be in a neighborhood…..only in Texas. The days we viewed the house happened to be some of the few days a year that the compressor was down for repairs or maintenance. On closing day when I walked up the stairs to turn the key in the door, I said to my self, “What is that noise.” After searching the neighborhood, we discovered the culprit to be a very old noisy natural gas driven compressor on a gas well. I fought that oil company for a long time and only was successful getting them to put up a wooden fence that did absolutely no good. Oil companies are King around here. They always expressed to me that they were compliant. They were, but this city has wimpy standards and codes that do not measure low frequency. We had spent lots of time, sweat, tears and money fixing up “this old house” and we did not want to move. We had redone the wooden floors ourselves, and I did not want to cover them up with carpet, even though that might have helped with the sound. We couldn’t afford to change out the old windows that were huge and had just been refurbished by me. Our home was built in an L shape facing the compressor. This was perfect for capturing the “waves”. They came right in through our large glass windows. In addition to that, there were metal awnings over each window acting like ears to reflect the sound in through the single pane windows. (I had refurbished those as well) The neighborhood was refreshingly quiet on the few days that “The Beast” was off for one reason or another. After three years of torment, the for sale sign went up. We disclosed the noise ( which probably brought our home value down) to the new buyer. She was not home much of the time anyway so she was not as bothered by it. The search for a quieter place was on. We were scared to think of buying again without knowing if “the sound” would be in that area too. , “ I had gone to look at houses for sale, just to see if I could hear how the house “sounded” and just to “test” a neighborhood. We decided just to rent. Little did we know that rental homes that are large enough for our family of six and that are in our price range are extremely hard to find in our town. We ended up having to grab a house when it became available just to get a decent place to live. As it turns out, we ended up moving from one frying pan to another frying pan so to speak. We have now been living in this rental for ten months and we are still plagued with noise problems. I say we because even though the others of our household are not as sensitive to LFN as I am, they still have to live with someone (the mom) who is and whose daily life is not as efficient as it could be were I able to sufficiently rest and relax. I went with our church on a mission trip to Mexico a couple of years ago. While up in a quiet mountain village, I discovered how wonderful peace and quiet were, and I realized just how much that LFN affected me while living in our bombarded home. Since we now rent, I can’t beef up the windows, but I have heard that double panes do not help with low frequency anyway. I’ll try to make a window plug to see if that helps. I can’t run the TV “off channel” because we need to concentrate and study at home. We are one of those homeschooling families. Also, that noise is annoying to my teenage daughter and me. You asked about whether or not other neighbors have had the same problems as I. I can’t tell you that. We haven’t gotten to know our neighbors very well yet. There are some factors to remember when questioning the neighbors about noise problems. Many in our neighborhood are retired and wearing hearing aids. They, of course, do not have problems with the noise. Second, if they did hear the offending frequency, they would be hesitant to say so in fear that this information might be something that could “go public” and cause their home values to go down. Third, low frequency noise is most often a source of annoyance to those fifty and older (I give away my age). The younger ones in the neighborhood have not yet reached that point. On a side note, there is an old man in the neighborhood who sits out in his attached garage with the garage door up for many hours a day. He will even sit out there when it is 100 degrees outside. I am just curious if he has a problem with LFN and is trying to escape it as I am. By the way, when I am out working in my ten by twelve foot shed (made of that composite siding stuff and sitting on wooden skids) I can’t hear or feel the vibration. This makes me wonder if the noise could be possibly ground borne. The LFN does seem to be worse when it is raining…..hum….saturated soil conducts noise very well doesn’t it. If the LFN was ground borne, would ….putting down a wood or laminate flooring that had a good coating of Green Glue behind it help. Is there any conclusive way to determine if LFN is indeed coming through a concrete slab? (I know this is some of that thousands of dollars of advice coming my way.) As was suggested, I am going to try to decouple the bed from the floor. I’ll order some sheets of sorbothane for that purpose. They are supposed to work better than rubber. What kind of instrument would measure the wall or slab vibrations? My son, who is now an engineering major (ME), once measured the sound with a microphone on his computer. Using music recording software, he measured the frequencies from 30 to 60htz or so. He had fun isolating the sound and turning it way up for all to hear and feel till we yelled at him to shut it off….ah teens. He captured it in the tile shower. So I know it is “out there” and not just “in my head”. It could be that I am one of those “hummers”. Read about them online. They can hear the Kokomo Hum, the Taos Hum, the London Hum, etc. There is even a low frequency sufferer’s society. This is your market for whoever invents a comfortable low frequency blocking head gear that can be worn at night. This wouldn’t block (as ear plugs do) the types of noise that parent’s need to hear at night. I would be interested in any tests like the one that one of the teacher’s mentioned ….measuring the frequency outdoors and comparing it to the indoor reading. I guess I just have to rent a device that measures what I need to measure. We would like to move, but as I said previously, I would not like to buy a home without knowing that I can block the offending noise that this town seems to produce whether from trains, underground gas pipes, well drilling, or chemical and manufacturing industries, etc. If we were to rent, we could not spend lots of money to “treat” the house for LFN. My husband likes his job and would like to stay in the area if possible. Me, I’d rather move to a small mountain village in Mexico. Or until then, I’ll just sleep with a pair of sorbothane shoe insoles smashed over my ears. I am glad you are teaching classes to train engineers in ways of mitigating noise and vibration, because ultimately these problems have a personal side and a personal face. If I have been a “textbook” case for you then so be it, and may you all become the best problem solvers in this area. If any of you have any other suggestions for me, send them my way. If you solve my problem, then my hat is (or should I say ear plugs are) off to you. Please do not share my e-mail address with the masses. My humble thanks, C

Home Low-Frequency Hum – House Is Literally Humming

The issue of home low frequency hum is discussed on several blogs. I did some searches om Home Hum Noise RE: House is humming, literally * Posted by kevin2009 (My Page) on Fri, May 1, 09 at 18:22 Have had exactly the same problem.

The issue of home low frequency hum is discussed on several blogs. I did some searches om Home Hum Noise RE: House is humming, literally * Posted by kevin2009 (My Page) on Fri, May 1, 09 at 18:22 Have had exactly the same problem. Problem so bad its been giving neighbors headaches-sleep pattern deprivation etc etc. A low resonant humming getting stronger at night etc etc. Not caused by traffic,electricity etc. Humming caused by water pipe vibrations causing all sorts of low frequency bass like wooing noises. Have found the problem tonight – pressure variance in water mains pressures.Too much pressure causes pipes to hum. Possible causes – pumping station pressures too high – pressure reducing valves malfunctioning – mains pipes causing transient noise due to a “Dead end” section of the mains pipe. Symptoms that can be checked – when the hum is at its loudest turn one of your taps on – the hum may reduce if the pressure lessens in the mains supplying the house – have you noticed any high flow/pressure rates from your taps? Not certain but a loss of water pressure may have similar properties also. This is definitely high time to contact plumbing service company like THA Heating, Air, and Plumbing Inc. If in doubt get your water utility company to do a flow/pressure check on the mains /in your house etc. The turning tap on trick will only work if its sufficient to reduce the mains pressure – if not try to get neighbours etc to turn theirs on at the same time etc. I live in England in wales in Newport. I will now update my posts when the utility company is made aware of the cause of my problem and tells me how they are going to fix it. This is a problem with humming that for me has been caused by mains water supply pressure problem – not necessarily your problem. There are many on call plumber in Fairfield with whom you can get in touch with to fix the damages that are caused to your plumbing infrastructure. 

Simply turning the stop cock to your house off is not enough – the problems still there because the pipes are still singing to the pressure problem. Hope this helps somebody. RE: House is humming, literally * Posted by peachiepie (My Page) on Tue, Jun 23, 09 at 17:31 Wow, I do not believe that so many people has the problem I have been having for three years. I am amazed when someone suggests tinnitus. I have explained I hear humming, not ringing. It is a sound and not a noise. Mine sounds like a low hum of a refrigerator or a motor lowly idling. I have had plumber, water, gas, power, and anybody else you can imagine here in my house in Georgia. This is a 1970s house and the hum began about two weeks after having a new water heater installed. The pressure was too high and the plumber  came in and corrected it. Two weeks later, the hum began. I don’t get a complete night’s sleep at all. What little sleep I get comes from le4aving the TV on late and then turning the radio on. Now, I can run the attic fan all night so I don’t have to hear it. Some people have heard it and others haven’t. I stopped mentioning it for fear people thought I was losing my great mind-lol. People still ask me time to time if I still hear it. I tell them yes. When the power is out, it’s just me and the hum. Drives me nuts. It is 24/7, never stops and in every room of my house. You can’t escape it. I had a client in my office and he asked, “what is that”. I said, oh you hear that. He said yes, what is it. I said, I wish I knew. There are a couple of things here that’s given me some hope. I will try the water trick, though I believe one of those professional plumbing contractors in the Oakland County area did all of thesse things. I will have the telephone company come out to check the lines. Everything else, I believe I have done. Good luck to all of us living with this in all areas of the country. Peachie

Unmanned Aircraft- Pentagon budget Calls For More!

U.S. Defense officials outlined plans to double production of unmanned aircraft, part of an expanded 2011 budget unveiled Monday. The budget will grow 7.1% to $708 billion in 2011. The Pentagon is one of the few U.S. agencies, mostly dealing with national security, that were cleared to receive budget increases under a spending freeze ordered by President Obama. Underscoring the Pentagon’s focus on unmanned aircraft in its 2011 budget, the Air Force for the first time is proposing the acquisition of more unmanned aircraft than combat aircraft. The Air Force will double its production of the MQ-9 Reaper, a bigger, more heavily armed version of the Predator drone, to 48. The Army will also buy 26 extended-range Predators. Overall, spending on the Reapers and Predators, which are built by General Atomics of San Diego, will grow from $877.5 million in 2010 to $1.4 billion in 2011. The expansion will allow the military to increase unmanned patrols — the number of planes in the air at once — to 65, up from its current limit of 37. Besides their use in international hot spots, Gates said, drones are useful for such efforts as countering narcotics trafficking and helping in natural disasters. “We will continue to see significant growth for some years into the future even as the wars in Iraq and Afghanistan eventually wind down,” Gates said. “The more we have used them, the more we have identified their potential in a broader and broader set of circumstances.” Read the full article here.

I think  this article from Reuters of interest to our blog readers interested in defense, submarines and underwater acoustics. http://www.reuters.com/article/idUSTRE5740DV20090805 WASHINGTON (Reuters) – Two nuclear-powered Russian attack submarines have been patrolling off the eastern seaboard of the United States in the first mission of its kind so close to shore in nearly a decade, U.S. officials said on Wednesday. CUBA PORT CALL One of the Russian submarines remained in international waters on Tuesday a couple hundred miles (km) off the coast of the United States, officials said. The second sub made a port call in Cuba in recent days, the New York Times reported, citing Defense Department officials who spoke on condition of anonymity. During the Cold War, the United States and Russia regularly sent submarines on secret missions near each other’s coasts. “It is the first time in roughly a decade that we’ve seen this kind of behavior,” Morrell said. Russia conducted a successful sea trial of the Nerpa last month in the Sea of Japan, according to the RIA news agency. During testing of the submarine in November, 20 people died and 21 were hospitalized when the fire extinguishing system was turned on in error, releasing Freon gas that asphyxiated the victims. The accident, the worst to hit the Russian navy since 118 sailors died in 2000 when the Kursk nuclear submarine sank in the Barents Sea, exposed the gap between the Kremlin’s ambitions and its military capabilities.

The battery-powered craft, which can stay airborne for about 15 minutes at a time, has been used at homicides and other incidents in northwestern Ontario to take aerial photos for use in court. It has helped reduce costs, too, as the provincial police would have otherwise brought in a helicopter or rented an aircraft. “We’ve saved over $30,000 the 11 times we used it,” says Const. Marc Sharpe, who operates the mini-helicopter. Aerial drones are usually associated with the military on overseas missions such as in Afghanistan and Iraq. But the remote-controlled aircraft are also starting to be used by police and firefighters in Europe and by various companies in Australia.

NASA’S SPITZER TELESCOPE WARMS UP TO NEW CAREER WASHINGTON — The primary mission of NASA’s Spitzer Space Telescope is about to end after more than five and a half years of probing the cosmos with its keen infrared eye. Within about a week of May 12, the telescope is expected to run out of the liquid helium needed to chill some of its instruments to operating temperatures. The end of the coolant will begin a new era for Spitzer. The telescope will start its “warm” mission with two channels of one instrument still working at full capacity. Some of the science explored by a warm Spitzer will be the same, and some will be entirely new. “We like to think of Spitzer as being reborn,” said Robert Wilson, Spitzer project manager at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “Spitzer led an amazing life, performing above and beyond its call of duty. Its primary mission might be over, but it will tackle new scientific pursuits, and more breakthroughs are sure to come.” Spitzer is the last of NASA’s Great Observatories, a suite of telescopes designed to see the visible and invisible colors of the universe. The suite also includes NASA’s Hubble and Chandra space telescopes. Spitzer has explored, with unprecedented sensitivity, the infrared side of the cosmos, where dark, dusty and distant objects hide. For a telescope to detect infrared light — essentially heat — from cool cosmic objects, it must have very little heat of its own. During the past five years, liquid helium has run through Spitzer’s “veins,” keeping its three instruments chilled to -456 degrees Fahrenheit (-271 Celsius), or less than 3 degrees above absolute zero, the coldest temperature theoretically attainable. The cryogen was projected to last as little as two and a half years, but Spitzer’s efficient design and careful operations enabled it to last more than five and a half years. Spitzer’s new “warm” temperature is still quite chilly at -404 degrees Fahrenheit (-242 Celsius), much colder than a winter day in Antarctica when temperatures sometimes reach -75 degrees Fahrenheit (-59 Celsius). This temperature rise means two of Spitzer’s instruments — its longer wavelength multiband imaging photometer and its infrared spectrograph — will no longer be cold enough to detect cool objects in space.

PALAOA – Transmitting live from the Ocean below the Antarctic Ice

Overview PALAOA area

You can listen to the underwater sound of the Antarctic Ocean with a delay of a few seconds here.  

– should work on any computer right off the box, otherwise please check your browser or default multimedia player settings.

Please note, this transmission is not optimized for easy listening, but for scientific research. It is highly compressed (24kBit Ogg-Vorbis), so sound quality is far from perfect. Additionally, animal voices may be very faint. Amplifier settings are a compromise between picking up distant animals and not overdriving the system by nearby calving icebergs. So you might need to pump up the volume – but beware of sudden extremely loud events. http://blog.wired.com/wiredscience/2008/05/hydrophones-hel.html

Hydrophones Help Scientists Pinpoint, Protect Right Whales

By Alexis Madrigal May 09, 2008 | 11:06:57 AMCategories: Animals, Web/Tech  

 

Regular Wired Science readers know that I have a thing for underwater microphones. Streaming the depths of the ocean to your laptop is just plain awesome. But now scientists are using them to do some good. Researchers at the Cornell Bioacoustics Research Laboratory and Woods Hole Oceanographic Institute have teamed up to use hydrophones to protect endangered whales off the coast of Massachusetts.

Using ten microphones attached by a stretchy data cable to buoys at the surface and special software that picks out the acoustic signature of right whales, the scientists are able to detect the slow-moving marine mammals. When a hydrophone hears a whale, it makes a cell or satellite call to researchers who contact ship captains to tell them to watch out. The map to the right is a near real-time detection map provided to you, at listenforwhales.org. It’s important work as less than 400 right whales survive and run-ins with ships are a leading cause of their death. 4   http://orcasound.net/  

A growing coalition of scientists, educators, and citizens are working together to expand a regional hydrophone network in the Salish Sea. This site is part of the SeaSound Project of The Whale Museum and is an experiment in sharing real-time underwater sound. The goals are to monitor the critical habitat of endangered southern resident killer whales to detect orca sounds and measure ambient noise levels.

Listen live via the links in the table or in the pop-up description you get by clicking the green markers on the map. For some hydrophones you can also watch live video from nearby (by clicking on the camera icons). The other icons show other hydrophones in the region that have not yet been networked. 2009 listening challenge: Help notify researchers when orcas are in the Salish Sea. If you hear killer whales please email detection@orcasound.net or log your observations in a collaborative Google spreadsheet. Use the Salish Sea sound tutor to learn to tell which pod is present based on the calls they use most often. Use web cams and other real-time sensors around the Salish Sea to figure out what else you might be hearing.  http://www.whaleacoustics.com/audio.html Baleen Whales Toothed Whales Dolphins Minke Whale Song Other Ocean Sounds  http://cetus.ucsd.edu/sounds.html The Voices in the Sea website demonstrates the diversity of marine mammals in the world’s oceans and the important role that sound plays in all aspects of their lives.

Uganda enlists help of U.S. sailors to locate plane crash wreckage By Sandra Jontz, Stars and Stripes Mideast edition, Thursday, March 26, 2009 Sandra Jontz/S&S Petty Officer 1st Class Michael Beauregard, a sonar technician stationed in Sigonella, Sicily, crouches next to side-scan sonar unmanned underwater vehicle. He and two other sailors will take three units to Uganda. NAVAL AIR STATION SIGONELLA, Sicily — U.S. Navy sonar technicians from Sigonella are in Uganda helping to locate wreckage of an airplane that crashed earlier this month killing 11 onboard. Sailors with Area Search Platoon 804, a support element to Explosive Ordnance Disposal Team Mobile Unit-8, began their work Tuesday, using unmanned underwater vehicles with side-scan sonar capability to search the depths of Lake Victoria, which at 26,560 square miles, is Africa’s largest lake. “We’ve been called to assist … to locate and map out the debris field for the aircraft and assist divers in the recovery of bodies and the flight recorders,” Chief Petty Officer Manuel Ybarra, a sonar technician who has served in the Navy for 24 years, said in a recent interview. The downed Ilyushin-76 cargo plane was en route to Mogadishu, Somalia, from Entebbe International Airport when it burst into flames and plunged into the lake after takeoff, according to a media report posted on allAfrica.com. A Burundian army general and his two senior colleagues, four Russian/Ukrainian crewmembers, a South African, an Indian and two Ugandans were killed in the crash, the site reported. http://www.stripes.com/article.asp?section=104&article=61590
