Boom Buster Noise Masking CD
The Boombuster CD is a specially filtered white noise maximizing the noise in the low frequency range where obnoxious bass noise lives (around 50-300 Hz). Because most normal stereos put out less sound as the frequency goes down, it is also filtered to increase the volume of sound as frequency goes down to counter this affect.
This CD will mask low-level bass boom without even being noticeable, and mask moderate-level bass boom when turned up loud enough that the noise is noticeable. High-level bass boom is so permeating that no product except an active noise-canceling headset (such as worn by pilots) will help.
