According to earphone manufacturers, people who often wear earphones to listen to music should master the “60-60 principle”, which is also an internationally recognized method of protecting hearing. That is, when listening to music, the volume should not exceed 60% of the maximum volume, and the continuous listening time should not exceed 60 minutes. In this case, ears are relatively healthy. In addition, try to listen to music in a quiet environment, and try to avoid hearing aids in some noisy places. Experts believe that once the external environment becomes noisy, the output effect of headphones will be interfered to varying degrees; and in a quiet environment, the output sound effects of several types of headphones are almost the same.
Earphone manufacturers tell that they are also particular about buying earphones. May wish to pick some earphones that can block external noise, hearing aids for the elderly to reduce the chance of increasing the volume of the Walkman due to environmental noise. Headphones are best to choose a head-mounted type. Children’s hearing aids have less damage to hearing than earphones.

The sound is all received by the tympanic membrane, and the hearing damage is even greater. Generally speaking, when Zhoucun hearing aids hear music at the same volume, the volume of earbuds is 7-9 decibels higher than that of headphones.
Headphone manufacturers outline that it is recommended not to use earbud headphones for a long time and at high volume to prevent noise-induced hearing loss. In recent years, hearing loss has become increasingly common among young people who wear headphones to listen to music. This is because when a person puts on the earphone, the opening of the external auditory meatus is tightly blocked by the earphone. High-volume audio sound pressure will directly enter the ear and damage hearing, causing irreversible hearing damage.
