Where To Find Pure White Noise
White noise is often touted as a remedy for sleeplessness, lack of concentration, or tinnitus. Much of what we consider white noise, though, is only an approximation of white noise. To find pure white noise, we must be a little more discerning.
Noises in the everyday world are often thought of as white noise. A fan running, the sound of the wind rushing by an open car window as you drive down the road, the sound of rain coming down on the roof and windows are all examples of noises people think of as white noise. These are not actually pure white noise at all.
Pure white noise is only produced when all the frequencies between about 20 Hz and 20 kHz are emitted together. That means all of the tones that the ear can hear must be played at once. Otherwise, you just have something that sounds something like white noise but isn’t really pure white noise.
This pseudo pure white noise can be somewhat effective at easing the roaring and buzzing ear noises of tinnitus. It may work well for some. But, it is not steady or convenient. It isn’t quite as successful at masking tinnitus noises as the real pure white noise is.
Pure white noise can only be obtained by manufacturing it. While other sounds may have many audible frequencies, only manufactured noise can have them all. This is done digitally to insure that all the frequencies in the audible range are included.
Sound conditioners are often used to produce pure white noise. These machines emit a noise that sounds like a wind or a fan, but actually contains all the necessary frequencies. They are available through home medical supply companies and catalog stores. They usually cost a few hundred dollars. Sound generators which can be worn like hearing aids can also play pure white noise. These, however, are more expensive.
White noise CD can be obtained through the mail, in stores, or over the internet. These are recorded from synthesized sound so that, for the length of the CD, there is no looping (repeating). They are very inexpensive, typically running you about $20. Then all you need is an ordinary CD player to use them with.
Noise that is nearly white noise is easy to find. Just listen around your house or yard. You will probably find some sound that will block the annoying ear noises of your tinnitus to some degree. However, if you want the effectiveness of pure white noise, you’ll probably have to go shopping for it. |
