People wearing headphones these days are really everywhere
On the subway, on the bus, on the train
Headphones have become the standard for many people on the road
As a result, many young people's hearing is getting worse and worse
But there are also those who disagree
Think it's psychological
Does total wearing headphones affect hearing?
Actually, tell everyone
Wear headphones for a long time in noisy environments
100% of hearing is impaired
Someone in our country once did an experiment
Looked for some young people around 23 years old
Let them wear headphones for 1 to 2.5 hours
After a long time
There will be a noticeable drop in hearing
The ear is a neuroreceptor
Same as the eyes
When it can't bear it, it goes wrong
The ear can hear the sound entirely by vibrating by the eardrum
If the hearing is impaired
It will cause a blood supply disorder inside
And once the injury is not reborn
Hearing can't come back
And wear headphones in noisy situations
The damage to the ears is greater
The normal noise outside is more than 60 decibels
It can reach more than 80 decibels on subways and buses
And you have to hear the sound in a noisy environment
The volume of your headphones must be higher than that volume
But even so the sounds outside
It will still pass through your skull
At this point, you will inevitably have to raise the volume again
This is bound to damage the cochlear hair cells
Causes irreversible damage to the inner ear
Transient injuries in general
After rest, you will slowly recover
But you wear headphones for a long time
But it is not transient but permanent
Noise It is divided into continuous noise and sudden noise
We have a muscle called stirrup in our ears
It shrinks when the outside world is loud
But if the volume is too loud
For example, suddenly you hear a loud noise in your ear
Then it simply didn't have time to react
I couldn't resist such a loud voice
It will suddenly reach the ear and cause damage to the ear
The best comfortable range for people is 50 decibels
You have to take a quantitative standard
You can remember 3 "60"
Do not wear headphones for more than 60 minutes
Sound cannot exceed 60% of the maximum volume
When the external noise is greater than 60 dB, try not to wear headphones
Xiaoxi: There are so many types of headphones now, there are in-ear, earplugs, hanging ears, bone conduction, and even headphones on glasses, is it that different types of headphones have different damage to the ears?
In-ear headphones
Its main purpose is to isolate the outside world from sound
People may have bought those headphones in the first place
It's all cheap and hard-made
So it is very likely that it will hurt to squeeze into the cartilage
Even if it is made very soft
There is always a foreign body in the ear
For example, it gets wet for a long time
Eczema, mold and these may occur
Elderly people wear earplugs for a long time
It can also induce fungal infections and otitis
In contrast, in-ear headphones will be better
Because it is physically wrapped by the ring
Cut off from outside sounds
Can better protect the ear
You may not actually have a very high volume inside your headphones
This way the sound is more directly against the eardrum
You feel that the sound quality of your listening may be better
Headphones in general vary
But again, the saying goes: don't wear it for a long time
