1. First of all, let's talk about the function of the human ear, the human ear has two major functions: hearing and balance. Only the former will be discussed here.
The transmission of sound is a complex process from the vocal body to the auditory center of the brain, and here we will only talk about a few.
Related to **.
2. Listening to the scene, the box, and the headphones, the reason why they feel different is because of the sound and the environment.
In addition to the different qualities, it is also related to the structure of the human ear, and there are two ways for sound to be transmitted to the cerebral cortex: air conduction and bone conduction. Normally, the first is predominant, but the latter is fast, which is also an aspect that makes us feel different when listening to the scene and listening to headphones.
3. Speaking of sound, the frequency of the sound determines the pitch of the pitch, the unit is hertz, and the range that the human ear can hear is.
Between 20---20000 Hz, and the frequency response of some headphones far exceeds this range, in fact, the human ear is.
Inaudible, but that doesn't negate the quality of these headphones.
4. The human ear has a different feeling of 20---20000 Hz, and is most sensitive to 500---3000 Hz. This.
It is precisely the frequency range of human language, so the human ear is better than the human voice than the high and low frequency instruments.
5. In addition, from a medical point of view, the sound of more than 90 decibels of sound will cause damage to the ear, and the sound of the ear.
The damage is proportional to the duration and intensity of the noise. Sound with high frequencies is damaging.
6, however, it is worth noting that the intermittent sound will be more damaging than the persistent one, which illustrates the average person usually thinks.
It's not right. 7. The reason why earbuds and earphones feel different is because of the grade and quality of the earphones on the one hand, and on the other hand.
The aspect is because of the structural problems of the ear, because a large part of the sound heard by the human ear is due to the external auditory canal.
The sound is best when the wavelength of the sound is four times the length of the ear canal.
8. There is one of the above items that can be known: large earphones with hanging ears and ear covers are superior to earbuds in terms of sound resonance, which is also.
One aspect of the sound of the average large headphones with earbuds is good, and certainly not the main aspect.
9, but there is a little difference, that is, the ER4 series earbuds, they are different from the average ordinary earbuds in structure, in.
Bone conduction has certain advantages, but the structure of the pronunciation is different, so it is much better.
These may be long, so give you the address and see for yourself, the most scientific way. )

Yes, yes, it is important to note that the volume is adjusted well so that it can avoid injury.
-
It's harmful! In particular, the sound should not be too loud, otherwise it will vibrate the eardrum!
Be careful.
-
It will affect your hearing later on. You'll find out when you're old, probably because you're young now.
-
Absolutely! Bad for the eardrums!

Of course, there is, and over time the hearing decreases.

Nowadays, many people like to wear headphones to listen to songs, so let me tell you what is the harm to your ears when you wear headphones for a long time to listen to songs.
01 Hearing loss: People who wear headphones for a long time to listen to songs, whether they are headphones or in-ear headphones, have certain damage to their ears. In the long run, it can lead to hearing loss.
02 Auricular pain: I don't know if you have this experience, wearing in-ear headphones for a long time, the pinna will hurt a little. Because the earphones are always placed in the ear, they will support the pinna, so it can cause pinna pain.
03 Memory loss: People who wear headphones for a long time will not only have damage to their ears, but also their brains. Studies have shown that people who wear headphones for a long time will have a decline in memory.
04 Danger: Nowadays, many people wear headphones when they walk on the road. This completely blocks out the horn sound. This is actually very dangerous because you don't know if you have a car behind you.

So how to define the fact of wearing headphones for a long time, ask you to think that you wear more than 8 hours a day for 3-6 months, of course, such a wearing time should do time-related work.
Returning to the question of listening to songs, we know that songs can be divided into various timbres, so if you listen to songs for a long time, the following situations are likely to occur:
1. It is easy to re-hear the sound of more than 85db for a long time, commonly known as deafness and deafness.
2. The residual solvent of the silicone on the earphone is released, and when it meets the ** of the external auditory canal, it inadvertently reacts, and it is easy to cause rashes, commonly known as allergies. In addition, silicone is a porous material that easily absorbs odors and secretions, and it is uncomfortable to think about it.
3. Long-term wearing of earphones will form an airtight closed cavity between the earphones and the external auditory canal, and the positive or negative pressure formed by placing or taking out will cause mechanical damage to the eardrum and cause perforation of the eardrum.
Well, don't wear headphones for a long time, it will be harmful to the eardrum, and hearing loss will be caused by a long time, and it is advisable not to wear headphones for more than 2 hours a day
Wearing headphones to listen to songs and foreign languages does not affect others, but also avoids external interference, which seems chic, comfortable and fashionable, but this way is unconsciously damaging people's hearing. At present, there is an increasing trend in the number of ear disease patients admitted to the hospital, and most of the patients are young people, of which more than 60% are young white-collar workers, especially young and middle-aged mental workers. The reason for this is closely related to the long-term use of headphones to listen to *** and play games. >>>More
If you use high-end headphones, forget it, because after manual debugging of high-end headphones, the damage to the ears of various sounds has been minimized, which can be ignored, but if LZ is a few stalls, it has to be ......Add to that the noise so loud that you could be in danger of becoming deaf in the future...... >>>More

With the development and utilization of edible fungi, the relationship between edible fungi and human health has attracted more and more attention. Scientific studies have found that children's regular consumption of mushroom foods is extremely beneficial to their health. As we all know, children's growth and development are inseparable from adequate nutrients. >>>More
