The 60-60 rule is a guideline from the audiology community designed to protect hearing from damage caused by prolonged exposure to loud sounds through headphones. It advises users to keep their device volume at no more than 60 percent of its maximum output and to avoid continuous listening for more than 60 minutes without a break. This rule is endorsed by organizations such as the World Health Organization (WHO), Mayo Clinic, and the Hearing Health Foundation.
Noise-induced hearing loss from headphone use is a public health concern. The WHO estimates that over one billion young people are at risk of permanent hearing loss due to recreational exposure to loud sounds. The National Institute of Deafness and Other Communication Disorders (NIDCD) reports that up to 17 percent of teenagers already show signs of noise-induced hearing loss.
The 60-60 rule is grounded in noise research. The National Institute for Occupational Safety and Health (NIOSH) established that sustained exposure to sounds at 85 decibels (dB) or above poses a significant risk of hearing loss. At 60 percent volume, most devices and earbuds produce sound levels between 75 to 85 dB. NIOSH applies a "3 dB exchange rate," meaning that for every 3 dB increase in sound level, the safe exposure time is halved. For example, 85 dB allows for roughly 8 hours of safe listening, while 100 dB reduces safe exposure to just 15 minutes. AirPods and similar earbuds can reach 105-110 dB at maximum volume, a level at which hearing damage can occur in minutes.
The inner ear contains thousands of tiny hair cells that convert sound vibrations into electrical signals for the brain. Prolonged exposure to loud sounds can cause these cells to fatigue and, in some cases, die permanently, leading to irreversible hearing loss.

The 60-60 rule, developed by the audiology community, recommends listening to audio at no more than 60% of maximum volume for no longer than 60 minutes at a time to prevent noise-induced hearing loss. This guideline is supported by organizations like WHO and Mayo Clinic, addressing a public health concern where over a billion young people are at risk of permanent hearing damage from recreational sound exposure.
