Headphones are a handy invention. You can loudly listen to anything at home or at work and not disturb anyone or neither can be disturbed by anyone. In other words, it disconnects them from you and you with them who disturbs you.
However, sometimes you have to pay for convenience. And improper use of headphones can provoke hearing loss.To understand how headphones work on our ears , we need to understand how we perceive different sounds. “Our hearing is electrical signals that certain brain centers perceive as sounds,” says Yuri Rusetsky, MD, otorhinolaryngologist of the highest category, Ear, Nose and Throat Clinic of the MMA named after MMA. THEM. Sechenov. – Electrical signals are generated by the sensitive cells of the organ of the Corti in the inner ear under the influence of vibrations (they are created by any noise) transmitted through the eardrum and the chain of auditory ossicles. Very strong fluctuations (that is, too loud noise) cause the death of sensitive cells, which is why hearingdecreases.

” Therefore, listening to loud music is harmful. And to enjoy it through headphones is more destructive for hearing than without them. After all, in “headphones”, sound losses are less and, accordingly, the intensity of sound is greaterThe innermost part of the ear, cochlea is a little less organ, and during one’s life, hearing is a process of continuously consuming a recession. And at the current level of human science and technology, there is no treatment and the loss is irreversible.The most important point is that due to the brain’s powerful compensatory ability, progressive hearing impairment is subjectively completely illusion less, unless the damage is already very serious, or the injury is sudden. The earphone’s harm to hearing is not because it is very close to the ear, but when people use the headset, it is easy to turn the volume too loud.
The “proper” use of headphones does not cause special harm. The problem is that almost everyone uses “headphones” as “inappropriate.” The key point is volume, use headphones in a noisy environment, if you want to hear music, then the volume must be excessive.
Buses, subways, trains, airplanes, busy streets, people talking indoors… almost every occasion that can be used for headphones is noisy.”Nature has envisaged a certain mechanism for protecting the ear from strong sound,” explains Yuri Rusetsky, MD, an otorhinolaryngologist of the highest category. “These are special muscles that tend to strain and limit the movement of the auditory ossicles in severe vibrations.
Thus, the “impact” on sensitive cells decreases. ” However, the muscles can not withstand a loud sound for a long time and after an hour their tension and, accordingly, the protection weakens. That is, if a person listens to loud music through the headphones for more than 60 minutes in a row, this will inevitably start to reflect on the rumor.
