Headphones seem to be the way to go ... ANR (Active Noise Reduction) headphones. Microphones in the headphone sample the noise that's coming at your ear. The information is analyzed and a precise active noise cancellation wave is generated. The result is a reduction in the background noise, and you can hear the music again! (Please Note: For those of you unfamiliar with Noise Reduction technology, only low, steady noises are affected by the circuitry. Voices, or other random noises will not be reduced though the closed design of these headphones will help a bit with those other random offending noises.)
ANR headphones reduce constant low droning background noises of which an airplane engine is one of the most common offenders. That's all the ANR headphones were designed to do! Random noises such as people speaking, baby's crying, bangs, clangs, etc. are not effected by the ANR!

This effectively hushes much of the sound made by planes, trains, and buses. We even subjected the QZ-2000s to a full-frontal New York City sonic assault, consisting of subways, noisy restaurants, and--worst of all--the unyielding din of midtown traffic. The noise-cancellation process pumps up the midrange to help the music cut through noisy conditions, which suggests that this unit is best for canceling fairly consistent noise. -----Original Message----- From: Michael Huffman [mailto:[EMAIL PROTECTED] Sent: Thursday, June 09, 2005 4:06 AM To: vortex-l@eskimo.com Subject: OT Noise Cancelation Moin Moin! ... Right between my apartment and this gorgeous view is a main coastal road that is used by all of the transport vehicles, as well as all of the emergency and police vehicles to service the outlying areas to the East of the city. The traffic is non-stop, and due to my proximity to the street, I sometimes wake up with the feeling that the last passing ambulance or police car just drove over the foot of my bed. It is driving me completely bonkers, and I have to do something about it. I would also like the solution to be something more interesting than stuffing cotton balls in my ears, or looking for another apartment. I read some years ago a little about various different noise cancelation technologies involving a microphone, a computer with a sound card, and a set of speakers. The basic idea was to take in a sound wave with the microphone, produce an opposite sound wave in the computer, and then blast it back through the speakers aimed at the unwanted noise source to cancel the sound. I have a bunch of computers around here that I could use, and I would welcome the opportunity to do a project. Does anyone here know of any links to homebrew noise cancelation solutions such as this?
