Wearing earphones to listen to music or foreign languages, not only does not affect others, but also avoids external interference, which is a natural, elegant and comfortable spiritual enjoyment. However, there are some potential hazards. Excessive use of earphones, the “Walkman” also become noise, noise harm to human beings in many ways, the most obvious damage to the hearing organs, people will unconsciously suffer from “sensorineural deafness” disease.
Use headphones for no more than 1 hour
Noise is a combination of many different frequencies and different intensities of noise. Whether exposed to a short period of strong impulse noise or repeated noise exposure for a long time, the hearing loss is called noise hearing loss, also known as noise hearing loss. Noise deafness is often seen in people working in noise environment, such as airport ground crew, textile factory and other industrial noise workers, as well as people who often wear headphones to listen to music and go to karaoke room.
Regular use of “Walkman” or earphones will damage people’s normal hearing, making people unconsciously suffer from “sensorineural deafness”. Relevant medical data show that when the volume of the human ear reaches 100 decibels, a long time can cause irrecoverable hearing damage; when the volume reaches 110 decibels, it is enough to cause the hair cells of the inner ear to die, and even cause hearing loss in serious cases.
At present, the volume of some MP3 players can be as high as 115 decibels. Even if the volume is not turned to the maximum, it can also reach 95 decibels when listening to rock music and more than 110 decibels when listening to disco music. Moreover, because many earphones are in ear design, improper use or too much volume can cause direct damage to the eardrum. Therefore, it is recommended that you use less earphones, and usually use the “Walkman” as low as possible, generally not more than 80 dB, and the continuous listening time should not be more than 1 hour.
In noisy places such as buses or streets, it is better not to listen to music with headphones, because in order to cover the noise, people often unconsciously increase the volume, which will cause more damage to the ears. In addition, don’t listen to the Walkman when you are sleeping, otherwise the earplug between the pillow and the ear will cause damage to the eardrum; if you are asleep while listening, the damage to the ear will be more obvious.
