How does loud music affect the ears?
Exposure to loud music, whether live or recorded, can damage sensitive structures in the inner ear, resulting in noise-induced hearing loss (NIHL). Once damaged, the sensitive structures, called hair cells, cannot repair themselves. NIHL is related both to the decibel level of a sound, as well as the length of exposure to it. Additionally, the risk of developing NIHL from exposure to loud sounds is cumulative, adding up over a lifetime of exposure. At what sound level can damage to the ears occur? Sound level (or more correctly sound pressure) is measured in decibels (dB). The lower limit of hearing is defined as 0 dB and a normal conversational level is around 60 dB. Sound reaching 85 dB or stronger, particularly if the exposure is prolonged, can result in permanent hearing damage. Many personal listening devices generate sound levels considerably higher than 85 dB. An average digital music player reaches 105 dB at maximum level, which is 100 times more intense than the 85 dB threshol
