The white sounds heard around our lives include the sound of rain, waterfalls, the sound of waves, the sound of streams, and the sound of branches in the wind. These sounds are familiar sounds that we usually hear, so while they may sound like noise, they are heard without much sound or psychological awareness. Plus, I feel stable because it's a natural sound I've always heard. Additionally, through the white tones of nature, we feel a sense of protection that we are surrounded by our surroundings as members of the universe, allowing listeners to relieve the feeling of silence in a de-audible way.
