What are harmful headphones and how to avoid danger. Otolaryngologist tips
If you have a smartphone in your pocket, with a probability somewhere near the headphones.It is very convenient to listen to your favorite music, book or language exercise in your free time. But as it turned out, it is not always safe. What can harm headphones, and how to avoid this harm?
There is a misconception that the headphones, tightly entering the ear canal, put pressure on it and stretch its walls. In fact, it is not the headphones themselves that are detrimental to hearing, but immoderation when setting the volume.
The design of the human ear is designed for a certain level of noise. Any sound, before we hear it, "rolls" on the auricle, the ear canal, there it becomes stronger and only then it hits the eardrum. Headphones "put" the sound directly into the ear canal. The sound can not be amplified in a natural way, so we twist the volume control.This is especially true of adolescents and young people.
If we ignore the main safety rule, which says: you can listen to music with headphones no louder than at 60% of maximum power, problems with hearing can be very serious. Moreover, the lovers of too loud sound hearing falls in a few days.

How to save hearing without giving up on headphones
Monitor the volume.If you do not want to believe the digital indicators, use other, no less accurate criteria. If, due to the volume in the headphones, you can not hear your own voice, the volume is dangerously overestimated. The same can be said if people around you can clearly hear the music from your headphones.
Too loud music is harmful with any model of headphones., but the model of “earbuds”, which needs to be completely inserted into the ear, is especially harmful, since the sound during their work bypasses the auricle membrane.
Listen to music for no longer than 60 minutesand no louder than at 60% maximum volume. At the earliest opportunity, remove the headphones and listen to music as usual.
While listening to music in headphones, there is an increased effect of sound on the hearing aid, including the eardrum. This can cause stretching and, as a result, lead to a decrease or complete loss of hearing. In order to reduce the effect of sound on a hearing aid, I recommend listening to music no louder than 60% of the maximum possible volume of the playback device.
I also recommend using the correct headphones. The safest are the so-called “mugs”, which completely cover the ear. And the most dangerous are vacuum intra-channel (in-ear headphones). Due to the vacuum, which is formed under the influence of these headphones, the expansion of the auditory canal occurs. Later, this can create additional problems: if a person has a hearing loss and you need to pick up a hearing aid, the expanded ear canal will not hold the device.
