Probably you have two or more phone jacks daisy-chained together. One cable goes to wherever the phone line enters the house and the other runs to another phone jack somewhere else in the house.
This is a common practice. I did some pricing online, and it seems that Cat 5e is comparable in price to 4-conductor phone cable, so the builders may simply have ...

The first thing working against you is that bass is the hardest frequency to dampen. With a wide wavelength, they travel further and induce vibrations in large objects. In short, the usual egg crate foam isn't enough.
The good news is that these are often custom built when created, and a simple Google search for bass traps will yield plenty of instructional ...

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 ...

As the other answerer said, it is difficult to stop low-frequency waves (eg, bass). I am in the middle of a major soundproofing project in my upstairs condo bedroom right now (it's a two-story unit sandwiched between two other units). My research over the past several months has introduced me to a number of products, only a few of which boast high ...

Yes, it's normal to hear a wood-frame house creak any time the wind direction or speed changes. How much creaking you will hear will also depend on the temperature differentials between inside and out, and the humidity. What you're hearing is minute changes in the wood as the pieces in the wood framing either rub against one another, or 'slide' on a nail.

Some motors have a start up noise, and is normal for that type of motor. My table saw does this. Starts out a loud 60 Hz hum which quickly increases in frequency as the motor spins up, then gets inaudible or washed out by rushing air when full speed is reached. Motors that do this are not really appropriate for residential blowers.
It also possible it's not ...

The first thing I would check, is to make sure there are no blockages in the vent. If there is debris restricting the flow of air, it could produce noise.
Another cause of this could be that the wind is blowing just rught across the top of the pipe causing it to vibrate, similar to blowing across the top of a bottle to produce sound. To prevent this, you ...

Our old one did this just as it was powering down - we traced it to one of the supports for the compressor being loose, allowing the compressor to vibrate, and as it spun down it went through a particular resonant frequency which induced a wobble giving it a few bashes off a metal guide - sounded just like you describe.
We connected another spring to the ...

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.

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 ...

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 ...

As you have deduced, the condenser coil needs to get rid of heat in order to work properly. If it cannot, the fridge will not work very well and it will eventually self destruct. So by providing a path to get rid of heat also will create a path to get rid of noise, so to speak. I suppose some elaborate baffled muffler system may attenuate the noise and still ...

While Tester101 provides a great answer for the classic case of water hammer, my situation is slightly different. The key piece of information from my question was that the noise occurred not only when faucets were turned off, but also when they were turned on. Doing a more focused web search on this turned up this post on TerryLove.com, which suggested to ...

The usual culprit is resonance. Your pump vibrates at a particular frequency, and while the mountings are usually damped using rubber bushings enough vibration passes to the floor/wall that anything else nearby that resonates at that frequency will vibrate if not fixed securely.
Ducting should be your first check, but also floor boards, drywall panels, or ...

You don't have a lot of info there. But it sounds like your bolt that is holding your main bearing for the main drum is coming loose. If it is a front load this is really easy to get to. Take off the back and you should see a large bearing. I had to replace mine for the same reason. It is held by one screw and has teeth that make the main drum spin. If ...

One possibility is a slight cracking of the stain or finish coat on as sections of the doors as they expand and contract based on changes in temperature and/or humidity.
Many doors have inset panels that are not rigidly glued in, but sit in channels in the rails (cross members) and stiles (upright members). When these doors are finished, the stain and ...

Most any material that keeps the wood to wood contact to a minimum should work. The most common material used is red rosin paper, but asphalt paper used to be an old favorite. I would avoid any thick absorbent materials like untreated felt or open cell foam, as they can absorb moisture or water and become moldy.
Use screws whenever possible instead of nails, ...
