Hearing impairment of ear
Compared with speakers, ordinary netizens think that headphones are more likely to damage hearing, and in-ear earplugs are the culprit. In-ear earplugs with the same volume stimulate the eardrum more than ordinary earplugs, so it will damage hearing. As far as the current situation is concerned, earplugs have been pushed to the forefront by various medical institutions and hearing rehabilitation institutions, and some countries have passed legislation to restrict users from using walkman in specific occasions.

In fact, long-term use of speakers will also lead to hearing loss, but the use environment is more casual and the use time is longer; But the relationship between location and time is not frequent, so earplugs are pushed to the scapegoat stage.
Stethoscope effect of inner ear earplug
First of all, we should explain what is called "stethoscope effect", because the cavity of in-ear earplugs will go deep into the ear canal, and the rubber sleeve of earplugs will also cling to the ear canal. If the wire of the earplug rubs against the clothes at this time, the sound will be transmitted into the earplug through the wire, resulting in annoying noise, which is similar to the noise generated by the stethoscope used by doctors, so it is called "stethoscope effect".
Wearing a ring helps to reduce the influence of stethoscope.
The auscultation effect often appears on earplugs with hard wires, because the noise seriously affects the listening effect, so in order to eliminate this annoying noise, netizens are desperately trying to find ways: wearing ear-winding method and clamping the wires with wire clamps. Some people even came up with the idea of wearing soft-soled shoes, and all kinds of patterns can be described as unique. It can be seen that the "stethoscope effect" is a huge weakness of the ear.
Earplugs are very dangerous.
As mentioned above, in-ear earplugs have a good sound insulation effect, which is more suitable for use in noisy environments than ordinary earplugs, but it can also be said to be a double-edged sword. It can eliminate noise pollution very well, generally eliminating the interference of 20-30 db, which sounds much better than ordinary earplugs in noisy environment, and can also filter effective information and block noise at the same time.
It's dangerous to cross the road with headphones on.
On the streets of vehicles and Malone, the sound of car horns and pedestrians will be filtered out by in-ear earplugs, and pedestrians will be in danger if they are not careful; Some manufacturers have realized this situation. Shure put forward the concept of "PTH push-and-listen" earlier, but this is only for the convenience of users to make calls without taking off their headphones, and the security has not been greatly improved. Moreover, the cable after PTH connection is too long, which increases the trouble of carrying.
Buy high-quality headphones.
When buying earplugs, you may wish to choose earplugs that can block the external noise, so as to reduce the chance of increasing the volume of the walkman due to environmental noise. The best choice for earplugs is headphones, which will not cause hearing damage like earplugs. Because the earplug is placed directly in the external auditory canal, the sound has no source, and all the sounds are emitted in the direction of the tympanic membrane, which is harmful to hearing. Generally speaking, listening to the same volume of music, the sound of earplugs is 7-9 decibels higher than that of headphones.
Shorten the time of listening to music.
Usually you can't listen to music for more than an hour every day. After listening for a while, take off your headphones and massage gently to relax your ears. In addition, don't wear headphones to sleep, or your ears will continue to be stimulated after sleeping, and the villi cells will be destroyed a lot unconsciously. When listening to MP3, don't listen to both ears at the same time. You should listen to it in turn, don't hold it too tightly.
