2. After studying the subjects with an average age of about 23 years old, the scientific and technical personnel in China found that the hearing thresholds of using earplugs 1 hour and 1-2.5 hours every day were significantly different from those of the control group.
3. Scientific and technical personnel suggest that using earplugs and headphones will lead to noise-induced hearing loss, especially in the high-frequency area above 4000 Hz, which is obviously greater than the low-frequency area. The longer the ear plugs and headphones are used, the more serious the hearing damage will be.
4. There are cochlear organs in human inner ear. Due to long-term over-stimulation, the metabolism of cells and tissues is disordered, and the blood supply and oxygen supply are insufficient, which leads to the damage of peripheral receptors and noise-induced hearing loss. ?
5. It is recommended not to use earplugs and headphones at high volume for a long time to prevent noise-induced hearing loss. In recent years, hearing loss has become more and more common among some young people who listen to music with headphones.
6. This is because when people wear headphones, the mouth of the external auditory canal is tightly blocked by headphones, and high-volume audio sound pressure will directly enter the ear, damaging hearing and causing irreparable hearing damage.
7. Listening to music with headphones for a long time will cause fatigue and damage to hearing, which will lead to hearing loss. The human body will have irritability, dizziness, insomnia, memory loss, inattention, slow thinking, psychological abnormalities and other phenomena, which is very harmful to health.
Extended data:
Although almost all earphones are designed with "open" earphones to reduce hearing loss, long-term use will still cause damage, especially when some people turn up the music volume to offset external noise.
Generally speaking, you need to pay attention to the following principles when using headphones:
First, don't wear headphones for a long time.
Second, don't turn the volume up too much. If people can't hear clearly from a meter away, you should turn down the volume of your headphones.
Third, choose to wear comfortable headphones.
In addition, earplugs are closer to the eardrum than earmuffs, which stimulates the eardrum more directly and may have a greater impact on the ears.
So it's better to try to use speakers.
