On the way to and from work, we saw that besides the “screen slaves†who focused on their mobile phones, they were also captured by ubiquitous headphones. People in the subway crowded in a group of headphones are silent, the air tends to stagnate, and everyone has a loud world in their ears. Relevant persons reminded everyone that wearing headphones for a long time can cause hearing impairment. It is recommended that people who wear headphones always use the following measures to improve their self-care.
People who often wear headphones to listen to music should master the "60-60" principle, that is, when listening to music, the volume should not exceed 60% of the maximum volume, continuous listening to music should not exceed 60 minutes.
It is best to choose a headphone Headset, it is less damage than the earbuds caused by hearing. The earbud earphones are plugged directly into the external auditory canal. Sounds are not heard from the eardrums. They are all directed toward the tympanic membrane. All sounds are received by the tympanic membrane, so the hearing loss is even greater. In general, listening to music at the same volume, the earphones are 7-9 dB more louder than the headphones. Headphones have better ventilation holes, which can discharge low-frequency signals with concentrated noise energy to the outside of the ear.
Try not to listen to music with headphones in a noisy environment. In subways and buses, users will involuntarily turn up the volume. In particular, the interior of the subway itself is a relatively closed environment. It will exert some pressure on the human ear. In addition, the earphones will be tightly pressed against the ears. High-intensity sounds will continue to hit the eardrum, causing damage to the hair cells in the cochlea.
