White sound is a type of sound that is produced by combining all the audible frequencies together and creating a constant, soothing sound. However, it is not the only type of sound that can help soothe or relax someone. There are several other types of ambient sounds that people may prefer, depending on their preference or purpose. One of these is pink noise, which has a higher frequency than white noise and is more soothing. Another option is brown noise, which has a lower frequency than white noise and can be helpful for masking external sounds. Other alternatives to white noise include nature sounds such as rain or ocean waves, or even soothing music.
