On this page you will find soothing sounds to help you cope with ringing in the ears, called tinnitus. When the cochlea is damaged, the brain perceives a signal at the frequency corresponding to a damaged cilium. Click on the ear above to see a movie about the cochlea (with sound, created by the people at Howard Hughes Medical Institute). Here is a wonderful video by 1997 Nobel laureate Steven Chu filmed at University of California Berkeley who hypothesizes ringing as oscillation of nonlinear Hopf oscillators comprising the cochlea. If you have normal hearing, these sounds will help you sleep, think, study, meditate, read, or concentrate. The sounds will induce a relaxed state and evoke a feeling of warmth. If you are in an office environment, these sounds will keep you from being distracted by people talking or background music. These sounds are designed to play on your computer or your portable MP3 player. TO LISTEN, LEFT CLICK. TO SAVE, RIGHT CLICK, THEN SELECT Save Target As...
