Have you ever encountered a situation, that it is too quiet to fall asleep? Perfect silence can indeed keep some people from enjoying a good night’s sleep. Sometimes a little background noise might be helpful for your sleep, sleeping with white noise can be one of your choices before going to bed.
What is white noise?
Simply say, white noise is a combination of all the sound frequencies humans can hear, such as the sound whirring fan, radio, or television static.
Technically speaking, the sound is measured by “frequency” in hertz, which refers to how fast the waves vibrate per second. While “amplitude” refers to the size of the waves which is usually measured in decibels. The relationship between the frequency and amplitude of a sound wave is used to define different “colors” of noise.
White noise is the noise that contains equal amplitude per frequency. The actual sound of white noise is typically described as a hissing sound, similar to the sound of the letters “sh” in the word “hush.”
Here are some examples of white noise:
- whirring fan
- radio or television static
- hissing radiator
- humming air conditioner
It is interesting to find that white noise can help mask other distracting sounds. Imagine your neighbor is holding a party at night, and then you turn on a fan to drown out the voices from them. In this sense, the drowning-out fan is similar to white noise.
