RP - White noise generators put out random frequencies at random
amplitudes over the audio bandwidth - 20 Hz to 20 kHz. Depending
upon the overall output level of the white noise generator, frequencies
from other sources with equal or lower amplitude levels will be
masked (covered or drowned out). Colored noise is weighted white
noise, that is, one or more frequency bands of varying widths
and center frequencies may have higher overall amplitude levels
relative to other frequency bands. On a synthesizer, the frequency
bands, their bandwidths, and their center frequencies can be programmed
to simulate a natural state. To some people these noise generators
create sound similar to ocean breakers, wind, waterfalls, and
the like; those people don't have very discriminating ears.
Electronic devices are widely available on the market today that
use digital recordings (samples) of natural noise generating phenomena.
On a number of DSS channels I see advertised units that incorporate
6 to 8 different natural noise generators such as rain, wind,
waterfalls, rain forest insects, ocean breakers, etc. that are
sold to people as relaxation aids and as a means of masking the
sounds of the house and the world at their bedtime. The devices
include programmable timers to switch them off after you've fallen
asleep. The devices are intended to mask the sounds of sources
inside the house, those that are often responsible for most of
the noise at bedtime especially if others are moving around in
the house. Refrigerators, dishwashers, clothes washers and driers,
heating and cooling systems, vent fans, blenders, plumbing and
showers, doors and windows opening and closing, televisions, radios,
sound systems, multimedia computers, telephones, people talking
- any one of those normal house sounds in the 1990s could make
it difficult for many to fall asleep; the electronic masking devices
are targeted at those people. For most people boom cars at bedtime
are an exceptional experience.
