After further examination by the otolaryngologist in the public hospital, Xiao Huang’s pure tone audiometry report showed that at the sound frequency of 4000 Hz, the hearing threshold (minimum audible intensity) was 65 decibels, no matter how low it was, it was “noise deafness”.

Xiaohuang found the hearing chain, after detailed inquiry, found the root of the disease – often wearing headphones to listen to music. During the bus ride, before going to bed at night, Xiao Huang will wear a pair of earphones to listen to music when he has nothing to do; in order to isolate the external noise, the volume is still loud.

Experts pointed out that often wearing headphones is one of the causes of “noise deafness”. It can “kill” the auditory cells in a pleasant way, and the phenomenon of “diving into the ear with the sound, silent after pleasure” appears. The earphone is plugged in the outer ear canal, and the hearing is slightly damaged in this case.

After testing, when the earphone volume is turned on to 50%, the sound pressure at the eardrum is about 70 dB; when the volume is turned on to the maximum, even more than 100 dB. According to the data of the American Institute of occupational safety and health, the sound intensity pressure is 85 decibels, and the longest time that human can endure is 8 hours; when it is over 100 decibels, the endurance time is less than 15 minutes. When Xiaohuang wears headphones to listen to music, and the volume is turned on large enough, his auditory cells have been slowly “killed”.

Doctors commented that young people who often wear earphones to listen to music and suffer from hearing loss have met many hearing professionals in the case of Xiaohuang. In view of this situation, three suggestions are put forward:

◆ stop headphones and rest for several weeks; take vitamins and vasodilators, and recheck the hearing after 3 months.

◆ if the public wants to isolate the surrounding noise, they can go to a professional hearing institution and match the “noise reduction earplug in the ear canal” according to the shape of the ear.

◆ if hearing impairment is serious, affecting life and work, and drug treatment is difficult to work, hearing aids need to be tested.
