Whisper Noise Canceler

Noisy neighbors keeping you up at night? Garbage trucks blaring before the alarm? Drunk revelers making it hard to hear the television? Soundproof your apartment by installing the Whisper Noise Canceler, an innovative acoustical system that promises to silence indoor noise. It works with an outdoor unit that is mounted on the exterior of a wall, door, or window and detects external noise. A corresponding indoor device emits anti-phase sound waves to counterbalance this and reduce the noise.
