　Jinghao听力专家说，现在的青少年手机不离身，听歌、看电影都把耳机往耳朵里塞，一戴就是几个小时，长时间戴耳机后耳朵出现耳痛、耳鸣、听力下降等情况。

Why do you wear earphones for a long time?

Because the ear canal is tightly blocked by the earphone when wearing the earphone, the audio pressure of the earphone directly acts on the tympanic membrane, which strongly stimulates the human cochlear organ. Even if the volume is not loud, the sound will stimulate the ear for a long time, which will lead to the metabolism of the inner ear cell tissue. Disorders and blood supply, insufficient oxygen supply, damage to the peripheral receptors, followed by neurological tinnitus, earache, hearing loss and other symptoms.

How to wear headphones to prevent tinnitus?

1, volume audio is adjusted below 4000 Hertz.

3, the choice of headphones, the contact area is large, to avoid clogging the external auditory canal, the internal pressure of the cochlea is smaller than the in-ear headphones.

4, choose to use headphones in a quiet environment, the earphones are the biggest damage to the ear under noise. In the noise, people will consciously enlarge the volume and impair hearing.

5, when wearing headphones, can distract people’s attention to the ear, so that the pressure on the inner ear is reduced, thus protecting the hearing and avoiding tinnitus.
