Why does wearing headphones hurt your ears?

It is said that earphone is more harmful to the ear?

Is there any kind of earphone that "does not hurt the ear"?

 

Can't you wear headphones to listen to music if you can't afford expensive headphones?

  

 No matter in the bus or subway, walking on the road or in the gym, we often see that many people wear headphones, listen to music, watch videos and brush Tiktok 

Such scenes can be said to be everywhere. Wearing headphones allows people to easily "isolate" from the surrounding environment, which seems to create an undisturbed "personal world", so comfortable. 

Then, the comfort brought by the convenience of earphones needs to pay a price.

According to the statistics of the World Health Organization (who), 1.1 billion young people in the world suffer from different degrees of hearing loss due to unsafe hearing behaviors. One of the important reasons is to wear headphones to listen to music.

How do earphones cause hearing loss?

 

In each ear, there are about 18000 tiny auditory hair cells, which are a vital part of the auditory system.

These auditory hair cells convert sound signals into electrical signals, and then send them to the brain, so that the brain can convert them into sounds that we can recognize.

Auditory hair cells are very sensitive to loud sounds and are prone to damage or death.

Wearing headphones for a long time and playing loud music or other sounds will damage the hair cells in the ear.

Unfortunately, human auditory hair cells lack the ability to regenerate. In other words, hearing hair cells are bad, no one, until they disappear forever.

Why is earphone particularly harmful to ears?

Earphones are earphones inserted into the ear canal. They are essentially small speakers that transmit sounds such as music into the ear canal.

Many general earphones are of poor quality, unable to block ambient noise, and poor in transmitting low-frequency sound.

Based on these two factors, users who wear earphones tend to unconsciously turn up the volume.

Compared with the earphone, the earphone of the earphone provides a certain buffer space between the music and the ear canal, which is relatively safe in terms of hearing protection.

However, many general earmuff earphones also have the disadvantages of poor quality and poor low-frequency sound transmission, so the music sound after turning up the volume is still easy to damage the hearing.

What kind of earphones are safer for listening to music?

Here, it is recommended to use two kinds of earphones to prevent external environmental noise and listen to music more safely.

The first is noise reduction earphone.

It usually uses reverse wave to reduce noise, and it is better to eliminate low-frequency noise. It can effectively reduce, for example, the buzzing sound of equipment engine or traffic noise, but it will not reduce higher frequency sounds, such as the speech sound of conversation.

The second type is acoustic earphones. 

Its working principle is different from that of noise reduction earphones. Instead, it forms a seal around the ear, which can form a physical barrier between the ear and external noise, preventing noise from entering the ear canal.

Can't you wear headphones to listen to music if you can't afford good headphones?

NO！

If you haven't bought expensive noise reduction or sound insulation headphones, don't be afraid. That doesn't mean you can't wear headphones to listen to music.

Whether you are wearing ordinary earphone or earmuff earphone, knowing the safe hearing restriction and using earphone safely can also protect your hearing.

For example, in order to ensure the safe use time, it is recommended to listen to the maximum sound of 85 dB for no more than 8 hours.

You may ask, how loud is 85 dB when listening to music with headphones?

Don't worry, we can change the method of using earphones, that is, the often said "60-60" principle: the time of listening to music with earphones should not exceed 60 minutes, and the volume should not exceed 60% of the maximum volume of the device. 

Therefore, if you are wearing headphones in the subway or exercising, it is important to master the volume and duration. 

Of course, in the days when you don't listen to headphones, you should also pay attention to those particularly loud voices in daily life, such as loud concerts or hi fan KTV.

After all, only by using your ears safely can you listen to more beautiful things!

 

1. Without ear dome, especially simple and convenient.

2. Not only is there no ear dome,still no howling (it is the  common problem so far but, ENNO solve it out by Japan technology)

3. The gain is more than 32db.
