[6] [7] [note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz [8] and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. [9] The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. [10]
Persistent sleeping disturbances can lead to fatigue, irritability, and various health issues. Numerous studies have examined the positive impact of music on sleep quality.

The human hearing range, for healthy young persons, is 20 Hz to 20,000 Hz. [13] Most adults can't hear higher than 15,000 Hz. [ 11 ] CDs are capable of reproducing frequencies as low as 0 Hz and as high as 22,050 Hz, making them adequate for reproducing the frequency range that most humans can hear. [ 11 ]
