The maximum volume of the headset is not more than 60%.

Professor William Shapiro, a hearing expert at New York university, cautioned that headphones are too loud to cause permanent hearing damage, especially among young people. According to statistics, one in five teenagers suffer hearing loss due to noise.
When a hair cell is damaged for some reason, it can lead to permanent hearing loss or loss of balance, she said. About 15, 000 cochlear implants, which are crucial for hearing and balance, are capable of translating vibrations into sound signals to the brain. These hair cells are very important, but they are very fragile, non-renewable and irreversibly damaged. To avoid external noise, many people like to wear earphones and have a quiet picture. In noisy environments, such as outside or in public transport, listening to music with headphones is unconsciously high. Studies have found that doing so often leads to deafness. The reason is that every 3 to 6 decibels increase in volume, the pressure of hair cells is doubled, and the closer the earplugs and eardrums are, the more pressure the sound has on the inner ear, and the more likely it is to damage hearing.
To protect your hearing, experts suggest that listening to music should be followed by a "golden rule" : no more than 60 percent of the volume, no more than an hour a day. In addition, using noise-canceling headphones can reduce the external noise, reduce the volume of the ear and protect the hearing.
