Sound masking systems are based on white noise technology. Just as there is a spectrum of light that goes from infrared to ultraviolet, there is an entire sound spectrum as well. Noises vary across the sound spectrum depending on the length and height of the sound waves. There are short waves, long waves, tall waves, and short waves. Sound masking works by filling up the whole spectrum, thus making one sound virtually indistinguishable from another.

Applying Sound Masking

Because white noise is inclusive of all discernable sound frequencies, it not only blocks out random sounds, but the white noise itself if basically unnoticeable. Sound masking is useful in a wide range of environments, with more and more practical applications developed everyday.

One group of people who have long reaped the benefits of white noise are the light sleepers. People who find it difficult to sleep above the sound of traffic, or planes, or barking dogs, or conversation, or dripping faucets, or noisy neighbors often use home made sound masking systems like a fan. Machines designed specifically for sound masking with white noise work even better. They are not too expensive either, which is nice.

Businesswomen and men also frequently require sound masking systems in their offices to ensure privacy of information. With so many people coming and going all the time, you never know who is listening to your private business conversations, so it's only logical to employ some kind of sound masking device to keep your private conversations private.
