Misuse of headphones, serious damage, hearing, 60-60 principle, ear damage prevention

The "60-60" principle is an internationally recognized method of protecting hearing, that is, when using headphones, the volume should generally not exceed 60% of the maximum volume, and can be adjusted to the lower level; the time for continuous use of headphones should not exceed 60 minutes. Adults should not wear headphones for more than 3 to 4 hours a day, minors should not exceed 2 hours, and every 30 to 40 minutes after wearing the headphones, the ears should be fully rested.

For those who wear headphones for a long time, it is recommended to choose a headset. The in-ear earphone has a small sound contact area and a large internal pressure on the cochlea; the headphone has a large contact area and a small pressure, and the stimulation to the cochlear ciliated cells is relatively small and safer. In addition, the high-impedance headphones have good sound quality and the volume is not too big. The noise-cancelling headphones can filter the outside noise, and it is also a good choice for people to listen to songs or rest quietly at normal volume to protect their hearing.
