The Sound of Silence
Friday, May 31, 2002
A traveller's nightmare: You check into your hotel room only to be subjected to the cacophony of your boisterous neighbours. If relocation is out of the question, why not create some noise of your own? Based on the principle of sound-masking, the portable Sonet Acoustic Privacy System (APS) by Cambridge Sound Management drowns out intruding noises.
Here's how it works: The brain normally focuses on the loudest sound it hears. If that noise contains information-like the sound of talking in the next room-the brain tries to process it, which is distracting. If a noise is produced that contains no information-such as the soothing, whooshing sound of the Sonet APS-it masks the unwanted noise. The frequency is low enough to block out street noise as well. The system comprises two speakers and a power supply, which together are no bigger than the size of a pair of shoes.
Installation is easy-the one minute it takes to set up the Sonet is well worth a sound night's sleep on the road.
