The so -called white noise refers to the power of the frequency component in a sound in a single sound component in the entire listening range (0-20kHz).Because human ears are more sensitive to high -frequency, this sound sounds very noisy.So what is the method of white noise headset?Lets take a look at it together.

White noise headset principle
1. Use a dedicated frequency generator to generate a certain fixed or scanning frequency and then enter it to the headset for a cooker. If there is no such instrument, you can use some programs compiled by others to make the machine.
2. For example, using a computer to process some waveforms and frequencies, and the output of sound cards can be used to achieve the effect of some real frequency instruments.
3. As long as the TTG is set at a low frequency, there are two ways to perform the machine. One is to use a fixed frequency output, and the other is to use the scanning frequency. Of course, the effects of the two are similar.
4. In the process of headphones, pay attention to the time for the machine to continue to work for too long, and the volume of the playback should be appropriate. Do not be too large, so as not to cause some damage to the headset, leading to the failure of the cooker.
