Will wearing headphones frequently cause deafness? Some medical data show that when the volume exceeds 85 decibels, long-term use can cause hearing fatigue. When the volume exceeds 110 decibels, severe cases can also 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.
In addition, the first occurrence of hearing impairment is high-frequency hearing loss, and the language frequencies we use in daily communication are not affected, so they are often ignored in the early stages.
Only when the hearing loss reaches bass extension and the speech frequency hearing loss reaches a certain level, subjective sensory hearing loss will occur, affecting language communication and social activities. Therefore, the effects of listening with headphones on young people often take many years to become apparent.
After research by our country’s scientific and technological personnel, subjects with an average age of about 23 years old used earbuds for 1 hour and 1-2.5 hours a day. There were significant hearing threshold differences compared to the control group. He suggested that using earplug-type headphones can lead to noise-induced hearing loss, especially in the high-frequency area above 4000 Hz, which is significantly greater than the low-frequency area. The longer you use earbuds, the more serious your hearing damage will be. Some scholars have also reported that exposure to noisy environments can cause first hearing loss at 4000 Hz.
There is a cochlear organ in the inner ear of people. Scholars believe that due to long-term excessive stimulation, cell tissue metabolism is disordered, blood supply and oxygen supply are insufficient, resulting in damage to the peripheral receptors, leading to Noise-induced hearing loss.
I would like to remind everyone that if you have high-pitched tinnitus (such as cicadas, whistles, metal sounds, etc.), you need to go to the otolaryngology department of the hospital for examination and treatment, which is very important to prevent deafness.
How to use headphones correctly?
1. Use the internationally recognized “60-60” principle to protect hearing.
WHO recommends that when using headphones, the volume should not exceed 60% of the maximum volume, and it is best to lower the volume to avoid over-stimulating the ears. It is relatively safe not to exceed 60 minutes a day, so people should wear headphones less and listen intermittently to give their ears sufficient rest.
2. Pay attention to the environment in which the headphones are used.
In a very noisy environment, if we wear headphones, we will unconsciously turn up the volume, so if the external noise is relatively loud, it is best not to wear headphones.
3. Sleeping and listening to headphones are not recommended.
When we sleep, if the ear wearing headphones is pressed against the pillow, it will damage the auricle and increase the irritation to the tympanic membrane. Also, if you fall asleep without taking your headphones off, you'll be wearing them longer.
4. When there is "rustling", headphones should not be worn.
When the earphones make a rustling sound or there is sound from only one side, it should not be reused. If you use headphones continuously, you may have long-term effects on your hearing imbalance.
5. For people who wear headphones for a long time, it is recommended to choose headphones.
The sound contact area of in-ear headphones is small and the pressure inside the cochlea is high. Headphones have a large contact area and low pressure, causing relatively little stimulation to cochlear ciliary cells and are safer.
