Here [Matthew Br] explains the situation he’s in with the neighbors that share this wall of his apartment. When they listen to music they like it loud and so he gets to ‘enjoy’ the experience as well. But he can’t ignore it any longer, and has decided to use a sound volume detector to blast [...]

Backyard parties are going to rock over at [Effin_dead_again's] house. That’s because he just finished building this outdoor stereo. It carries its own power supply so you can take it on the road with you, and we don’t think you’ll have trouble hearing it with the 240 Watt amplifier hidden inside. He shared the equipment details [...]

Shop-Vacs are great tools, but they do have the notable disadvantage of being loud.  Fortunately, much of the noise emanates from the exhaust, and with a muffler or “silencer”, this can be controlled. The results of my noise-recustion experiments were noticeable, reducing the noise by roughly 5.6 decibels. This may not sound like a huge [...]

[Ed Rogers] has the unfortunate privilege of living right next to a set of train tracks, and as a man who holds his sleep in high regard, he needed to find a way to keep the noise in his bedroom to a minimum. To combat the sound of passing trains, he built himself a system [...]

In what can only be described as a truly bizarre hack [CNLohr] discovered that the RF noise from the computer can be used to play music through the guitar’s pickup. Check out the clip after the break to hear an annoying, but [...]

[Miceuz] just finished his first surface mount electronics project. It’s a pink noise generator that is used for testing audio equipment (scroll down that link for the English version of his writeup). Pink noise is somewhere in between red noise and white noise. Didn’t realize there were more colors than just white when it comes to [...]

This looks very much like a violin but it sounds very much like someone abusing a family of cats. [Ranjit] came with the idea of building a violin using laser cut parts. It doesn’t follow the normal curved shape we’re used to seeing with string instruments. This is because the parts were all cut from [...]

[Jared] often needs to be on conference calls for work during his motorcycle commute. He’s got a bluetooth headset that cancels noise but it didn’t have a mute feature. He cracked open the speaker and microphone portion of the apparatus but there wasn’t enough room for a switch. The base unit which houses the noise [...]

Here’s an interesting idea: replace a disposable coin cell battery with a capacitor in order to filter the noise from an external power supply. [David Cook] is taking advantage of the falling costs of digital calipers. He’s mounted one on his milling machine but noticed that with an external power supply the readings would sometimes [...]
