Quizplus · Accepted Answer

Hair cells in specific regions of the cochlea are responsible for discriminating different pitched sounds. The cochlea is tonotopically organized, meaning that different frequencies of sound activate different regions of the cochlea, and hair cells in those specific regions respond to those specific frequencies. So when we hear a high pitched sound, it is because hair cells in the region of the cochlea that responds to high frequencies have been stimulated, and when we hear a low pitched sound, it is because hair cells in the region of the cochlea that responds to low frequencies have been stimulated.
