Under normal circumstances, the volume that the human body can bear is below 80 decibels. If you live in an environment above 80 decibels for a long time, you will have a headache, memory loss and insomnia. When the volume heard by human ears reaches 100 decibel, it will cause irreversible hearing damage for a long time; Long-term exposure to the volume above 120 dB will cause permanent damage to auditory cells, and even lead to hearing loss in severe cases.
So, how loud is listening to music? The following is the volume of several kinds of noise, which you can compare.
Volume comparison:
Maximum MP3 volume: 120 dB
Aircraft take-off sound: 120 dB
Electric drill sound: 100 dB
Noisy bar: 90 decibels
Urban area: 70 decibels
General conversation: 50 decibels
Quiet dialogue: 30 decibels
Therefore, the highest volume that MP3 can achieve is equivalent to the sound of an airplane taking off.
In fact, any sound above 85 decibels will cause hearing damage, because this damage depends not only on the volume, but also on the length of contact. If you are exposed to 90 decibels for 8 hours every day, it will be enough to cause gradual and irreversible hearing damage. Therefore, experts also pointed out that in fact, listening to music is not innate, but caused by improper use.
What should I do if I don't want to be deaf and regard music as the source of spiritual vitality? Change the habit of listening to music from today, and cherish your ears while enjoying music!
Suggestion 1: Buy high-quality headphones.
Headphones should be of good quality, low noise, and the volume can be adjusted freely, which can be adjusted in time in case of excessive noise. Earmuffs are recommended because they do less harm to the ears than embedded headphones.
Recommendation 2: Don't listen to music while sleeping.
When I sleep, my ears are constantly stimulated by music, and my hearing is unconsciously damaged.
Suggestion 3: reduce the time of listening.
Don't listen to music for a long time. Give your ears a rest every half hour, not more than three hours a day. Of course, the less the better.
Recommendation 4: Try to listen in a quiet environment.
Don't listen to music in noisy public places, because it takes a lot of volume to drown out the noise.
Recommendation 5: Control the volume.
It is best to control the volume of listening to music at about 60 decibels, with a maximum of 80 decibels, so as to feel comfortable and happy.
