Nowadays, the use of headphones is already a very common phenomenon. Doctors say that in recent years, hearing loss has been caused by wearing headphones for a long time. Many people like to listen to headphones when they take the subway, will it be harmful to our hearing?
Life Times pointed out that when the sound continues to be higher than 85 decibels, it will cause auditory fatigue. The noisy ambient sound of the subway and buses is about 80 decibels, and when people wear headphones to hear the music clearly, they will naturally adjust the volume to a higher level than the ambient noise, and they will be unaware of the high volume.
The treble constantly impacts the fluid in the concussive cochlea, and the hair cells of the inner ear die from overstimulation. It is recommended to follow the 3 60 principles of using headphones: the volume of the headphones is less than 60% of the maximum volume, the continuous listening is less than 60 minutes, the ambient sound is less than 60 decibels, and it is not worn in the environment of buses, subways and other environments.
It is worth noting that noise-cancelling headphones may also damage hearing.
Experts say that even if the noise-canceling headphones are too high, the sound output in the headphones may damage the hearing. Therefore, no matter how the "noise-canceling headphones" are, reducing the noise in the ear canal is the king of hearing protection.
In addition, the "bone conduction headphones" that appeared as "black technology" are popular with many fitness people and outdoor enthusiasts.
Experts pointed out that whether it is bone conduction or air conduction, both headphones finally make the hair cells of the inner ear vibrate to cause hearing. If the volume is too loud, it will still cause damage to hair cells, which in turn will damage hearing.
