Will wearing headphones frequently affect your hearing? Why?
The ear is composed of three parts: the outer ear, the middle ear, and the inner ear. The outer ear receives sounds from the outside, causes the tympanic membrane to vibrate along the ear canal, and transmits the sounds to the inner ear, and then to the hearing center in the brain through the auditory nerve. , and then the sound was heard.
The frequency range of sound waves that the human ear can generally detect is 20-20,000 Hz. Hearing is more sensitive to the sound wave frequency of 500-1000 Hz, but not sensitive to noise between 2000-4000 Hz. If you use headphones for a long time, your hearing will be damaged in the high-frequency sound wave part (2000-4000 Hz). Therefore, even if the hearing has been damaged, it is difficult for us to notice it. By the time we notice it, the hearing damage has already been serious, which may cause noise-induced deafness.
An important cause of hearing loss is noise. Noise-induced hearing loss can be divided into chronic and acute. Acute injury is close-range, sudden strong noise. And chronically, it means chronic hearing damage caused by long-term exposure. For example, when listening to headphones for a long time, the sound pressure is concentrated on the eardrum, which can easily cause auditory fatigue. And due to long-term excessive stimulation, peripheral receptors are damaged, leading to tinnitus, heavy hearing, ear pain, and even hearing loss.
Some medical data show that when the volume exceeds 85 decibels, long time can cause hearing fatigue; when the volume reaches more than 110 decibels, severe cases may cause irreversible hearing damage. The volume output of headphones is generally around 84 decibels, and some high-frequency ranges can reach 120 decibels. Such volume has a great impact on hearing. Moreover, hearing loss first occurs in high-frequency hearing loss, but the language frequencies we use in daily communication are not affected, so it is often ignored in the early stage.Extended information: The correct method of wearing and using headphones is as follows
1. Reduce the time of using headphones and strictly follow the "60-60" principle.
The so-called "60-60" principle refers to an internationally recognized method of protecting hearing, that is: when using headphones, the volume should generally not exceed 60% of the maximum volume, and it is best to adjust it to a lower level; The time of continuous use of headphones should not exceed 60 minutes. Adults should not wear headphones for more than 3 to 4 hours a day, and minors should not wear headphones for more than 2 hours a day. The ears should be fully rested after wearing headphones for 30 to 40 minutes each time..
2. Never sleep with headphones on.
It is difficult to control your posture during sleep, which not only causes noise damage, but also easily compresses the earphones, causing physical damage to fragile ears.
3. Don’t listen to music in a noisy environment.
When you find that you still can’t hear clearly when the volume is turned up to 60% in a noisy environment, it’s time to take off your headphones. If you continue to listen, it will only damage your ears.
4. Use headphones with noise reduction function.
Try to use over-ear headphones; try to use headphones in a quiet environment; try to use headphones with noise reduction function, because active noise reduction headphones can reduce the impact of noise when listening to music. On the other hand, Help us lower the headphone volume.
