Often listen to headphones deafness 30 years in advance

Noise is one of the common causes of hearing loss. In recent years, with the popularization of electronic products such as mobile phones and tablet computers and the increase in entertainment venues such as karaoke bars and bars, the public, especially young people, are increasingly at risk of noise-induced hearing loss (noise deafness) due to improper ear use. Relevant research at home and abroad shows that 12% to 15% of young people's hearing health is affected by entertainment noise.

On the way to and from get off work, we often see people who wear headphones to listen to music and watch videos. Headphones have become an important line of business for many office workers. Due to the noisy environment in subways and buses, in order to hear the sound in the headphones, people will unconsciously turn up the volume. As everyone knows, this is one of the reasons for the slow decline in hearing-close-range high-decibel noise can cause damage to the inner ear hair cells or even death. Over time, it will cause noise deafness. This damage is often irreversible.

Noise-induced deafness has previously appeared among professional people working in noisy environments, but in recent years, it has often occurred to young people who like to use headphones, and even people who often cook on the phone cannot be spared.

We know that when the human ear accepts momentary strong noise. If you hear gunshots, firecrackers, tinnitus, hearing loss, etc., there may be serious hearing damage if you touch it once. But long-term exposure to continuous noise is no less harmful than strong noise. Studies abroad have shown that wearing headphones for a long time to listen to songs can cause deafness to arrive 30 years earlier.

Special Note

How to use headphones scientifically

1. Wear headphones to master the "60-60-60" principle. That is, when listening to music, the volume should not exceed 60% of the maximum volume, the continuous listening time should not exceed 60 minutes, and the external sound should not exceed 60dB.

2. Choose a headset. Earphones are generally classified into three types: head-mounted, ear-hook, and in-ear, of which the ear damage is least.

3. Try not to listen to music with headphones in a noisy environment. In addition, when listening to music, do not excessively pursue the sound quality effect, and put the low-frequency sound very large.

4. When there are tinnitus, stuffy ears, dizziness, inattention, etc., you should be vigilant.
