What is white noise? White noise is a random signal with average power that is evenly distributed throughout the spectrum. Its energy is equal at all frequencies and there is no frequency bias. It sounds similar to static noise, similar to the sound produced by a TV or radio in the absence of a signal. What is powder noise? Pink noise has a higher energy density in the low frequency region and gradually decreases in the high frequency region. The power spectral density of powder noise is attenuated by the inverse of the frequency. It sounds similar to many sounds in nature, such as raindrops, heartbeats, etc. What is brown noise? Brown noise is also known as Brownian Noise, named after Brownian Motion. It has a high energy density in the low frequency region and gradually decreases with the increase of frequency. Brown noise is similar to some phenomena in nature, such as wind, sea waves, etc. In general, these three types of noises are beneficial to the human body. We can actively make these noises to help ourselves relax our emotions, reduce pressure and help sleep. And Noisedash implements this function.
