Most refrigerator alcoves are mini reverberation chambers, having hard sides. You may be able to place acoustic foam behind the refrigerator to absorb the sounds. If you're handy sewing, you could copy this design for a sound reduction blanket using polyester fiber fill used for coats. As a trial, just loop a couple of layers of the batting off a couple ...

Bleeding radiators is quite simple, and can usually be done by homeowners. All that's required is a radiator key, a towel and/or bowl, and a bit of time. Why Bleed Radiators Even with closed systems, air can still find its way into the system. When it does, it will collect at the highest points available (the top of radiators). Trapped air can cause ...

Is your generator producing true sine wave, modified sine wave, or square wave output? The motor's designed to work on sine-wave AC, which is what large generators are happiest producing, and which is generally the most efficient form since all the energy goes into the single frequency and can be easily drawn back out. Square wave is easier for small ...

The best way to eliminate transformer noise is to purchase a quality transformer. The noise is because the laminated core is heavily loaded or overloaded and the plates are actually vibrating because of eddy currents. I can’t quite make out the size, but it looks like 24V, 20VA. I would bump it up to a 24V, 40VA unit that would be compatible with video ...

Popping sounds are generally either a sound from a spark, or a failure of an electronic component. They do not always mean that something failed. For example, plugging in electronics that use lots of power will often cause a small spark to form when plugging them in. As an example, my Lenovo laptop power adapter will often make a sparking noise when I plug ...

If you can disassemble the frame, separate the siderails from the head and foot boards. Use a crayon or candle to wax the mating surfaces of the wood. This will help eliminate the squeeks. If the bolt has machine threads apply a small amount of thread lock (Loc-tite) which is available at the local hardware store. Get the smallest tube you can as you ...

GE dishwasher won’t drain. Washer is washing, but doesn’t drain. During drain cycle you hear a hum, but no water is flowing into the garbage disposal. Troubleshooting: Two common problems: 1. Drain hose is blocked at the garbage disposal or anti-siphon air gap connection. 2. Something is stuck in the drain pump so that the impeller blades can't turn. ...

Plant climbing vines at the wall, let them climb and cover. Take note of the "sound walls" around the interstates or beltways around the cities. Many have vines growing over them to aid in the sound deadening. Find what the specie is and go from there.

Throwing the main breaker on your electric panel is easy; you should try that. If cutting the power to the whole house stops the problem, then turn the power back on and start turning off circuits one-by-one. Hopefully they're labeled so you can identify the appliance or room, but this may take some trial-and-error. Here are some other possibilities I can ...

Keeping the fridge full of stuff may stabilize the temperature and reduce the number of times the compressor turns on and off.

I hear the same noise and have done in a few houses. After years of chasing sounds round rooms I'm pretty sure the culprit is a tiny brown beetle I've found a few times, 1-3mm max. I'm struggling to identify it. My ex wife could hear it so I knew I wasn't going mad! It can really keep you awake for such a quiet sound! I live in West Wales in the UK.

Here in Southern California when tract homes are constructed along freeways a block wall is constructed the length of the lots. Similar to yours I'm guessing. Rather than having a smooth and flat surface the face of the blocks are irregular and textured. Some project several inches past plumb while others look to have an angled face. It would appear that the ...

First, even though the exposed wires are low-voltage, likely 16 VAC, they should be covered for esthetics (if the transformer were accessible to children, not inside a closet, it is likely required). That said, the buzzing noise is likely being transmitted to the metal plate and wall, which make it much louder. A few things to reduce the buzz: Remove the ...

A short or arcing would most likely sound more like a buzzing (but could sound like a hiss, I guess) but would also be accompanied by smoke, a nasty "fried circuitry" ozoneish smell, and black soot marks near the source. I have never heard of this being a common source of danger for anything besides fire and/or shock. I think it is way more likely ...

I'm not sure why you're suddenly having trouble with water hammer, the old plumbing may have been installed in such a way as to mitigate water hammer. Since I have no way of knowing what the old plumbing looked like and/or what you changed, I can't say for sure why you're having trouble. So I'll simply talk about a couple ways of stopping the hammering. The ...

Listen, sound patterns travel in the weirdest ways. My house is on a hill and there is a college a block away. Every night my house was shaking from bass and I was like "what the hell". I am thinking the kids were cranking up their bass so I ventured out on a recon mission. After a few nights of visiting the parking lot area I did realize it was a few ...

A white noise generator is like spraying perfume to cover a nasty smell. The smell is still there, just the perfume is stronger. The nastier the smell, the stronger the perfume needs to be to cover. A white noise generator produces noise that our brain quickly ignores. If this noise is louder that the outside noise, then it will mask it. But a word of ...

You could try partially closing the water supply shutoff valve to the water tank unit. This would reduce pressure and flow rate some and thus could also reduce the noise produced in tank. If you do decide on this approach make sure to test it out a number of times to make sure that the flush operation and the refill time are suitable.

You can buy sound deadening panels or sheeting - You would construct a fence-like structure inside your block wall, then hang the sound absorbing panels or sheeting from that. The material can be part-covered with regular wooden fencing, or plants, or painted, or a combination. You may be able to get away with only performing this treatment on a couple of ...

I've attempted to build a reasonably soundproof music room in my basement and can tell you it is a tall order. I built a room when finishing my basement using double drywall with Green Glue, a floating double drywall ceiling with hat channel and isolation clips, sealed outlets, and re-routed HVAC and it I can still only play at a moderate volume without ...

As an engineer having dealt with window and wall mount A/C noise problems for over a half century, I can offer you the most likely cause of the noise transmission and the solution to solve the noise problem. But first, we must understand that most, if not all, resonate noise vibrations in such units are being emitted by the compressor. Yes, the electric ...

I don't know if this is a legitimate answer, but I'd reconsider a hand saw. Depending on what works well for you, and what you need to do with the saw. I'd try a pull saw, very easy to use and makes a nice clean cut, almost anyone can get good results with this type of saw. They don't bind and they are very easy to get started. The way the blade is made, ...

Posting as answer: Did you try shutting off power to your house at the main breaker? That would rule out any AC-mains connected devices. What about your toilet? The fill valve can make noises like this and it can be continuous if it's leaking.

A "globe valve" would be more suitable for the task. Both ball valves and gate valves are intended primarily for shutoff - either fully open, or fully closed. A likely noise source is cavitation (bubbles forming and then collapsing) at the sharp edges in the flow when partially open. A gate valve has a plate with a (relatively) sharp edge that will ...

Couple options come to mind: Change the fan. Change the fan speed. Change the fan connection to the vent. Dampen the vent. Change the size or length of the vent. If you can't or don't want to change the fan, then try dampening the vent by clamping it somewhere to the building structure and possibly adding some padding or pipe insulation where it makes ...

Is there any chance that, with the new sump, you also had a radon mitigation fan installed? A radon mitigation fan runs continuously. They are placed outside the living space - so in the attic, or sometimes in a box on the side of the house. They are not small. Failing that, I suggest you go put your hands on the sump cover to see if you feel it there.

First guess: sticky paint. With the screws loose, there's less contact between paint on either side. See also Doors are sticky and noisy when opened?

There are a number of companies that provide windows with high STC ratings. The series 7000 windows from http://www.silent-guard.com appear to have STC of 40 and above. There are many other manufacturers that sell sound attenuating windows. I believe you are correct that to get what you want you'll have to specify specific windows. The way you describe ...

It's probably just the pipes expanding and contracting under temperature changes. They can bind on an anchorage, then suddenly break loose. The floor and pipes do reverberate, amplifying the sound. The tension release and sudden movement can be very small, yet the resulting sound rather startling. If you can identify where the pipe is hanging up, you can ...
