WHO shows that there are currently about 1.1 billion young people (12-35 years old) in the world face irreversible hearing loss due to excessive volume of personal audio device (such as listening to music with headphones).
No matter what kind of headphones you are using, it will not avoid the direct stimulation of sound on cochlear and tympanic membrane . Long-term use will damage hearing.
wear headphones
Because, under normal circumstances, the sound can only enter the ear after a distance, and the high-frequency part of the middle sound has been absorbed by the air.
Relying on headphones to transmit sound, the eardrum is very close to the earphone vibrator, the sound wave conduction range is small and concentrated, and the sound pressure will directly enter the ear and spread to the very thin eardrum in a concentrated manner, without any room for buffering.
In our common flat-head, in-ear, and head-mounted headphones, especially in-ear headphones, the damage to hearing is greater.
Otologists once suggested a simple method: wear headphones to follow the "60-60" principle, that is, the volume of the headphones should generally not exceed 60% of the maximum volume, and the time for continuous use of the headphones should not exceed 60 minutes.
Adults should not wear headphones for more than 3 to 4 hours a day, and minors should not exceed 2 hours.
In addition, in places with particularly noisy environments, don’t wear headphones. Because in this environment, we always unconsciously turn the volume up, which can easily cause hearing damage.
Finally, the headphones cannot be ignored. It is best to clean them regularly and keep them clean!
Because, earphones that have been used for a long time will depend on a large number of bacteria, and the damp ear canal is closed by the earphones, which is a good environment for bacteria to grow. Once an infection occurs, it is easy to not heal for a long time, which will seriously affect hearing.
