What can be harmful from headphones

According to otolaryngologists, similar audio devices, undoubtedly, have a negative effect on the human body. The degree of damage depends on the type of construction, signal transmission format, loudness and other circumstances, but in general, the harm of headphones can be like this:

  1. Hearing loss.
    Loud sound from 100 dB is a real threat to the human hearing organ. For safe use, you must adhere to values ​​u200bu200bhalf. Hearing loss is gradual, so it's impossible to notice.
  2. The headset depresses the brain.
    With regular and long-term use of the ears, a person begins to suffer from various problems with the central nervous system - these are headaches., bad memory, insomnia, irritability, distraction, etc.. The harm from headphones in this case is not only sound, wireless devices also irradiate the brain, although much less, than a phone, brought to the ear.
  3. An important organ is located in the inner ear, which does not matter to hearing is the vestibular apparatus, positioning of the body.
    With the negative impact of loud sound, a person has problems with coordination of movement, dizziness and even nausea.
  4. The headset also affects the state of the vessels of the brain.
    Abuse of the device provokes vasospasm, their constant contraction, high blood pressure.
  5. Intracanal devices or plugs prevent the ear from being cleared of wax, resulting in the formation of congestion.
Certainly, more harm is manifested in those, who constantly listens to music at full volume. There may be severe hearing loss, migraine, nervousness.

Hearing damage when using headphones

The main harm of headphones is the volume of sound and pressure on the eardrum and organs of the inner ear.. Constant influence at high volume reduces the sensitivity when perceiving sound.

Are wireless headphones harmful?? How to protect yourself?

There is an organ inside the ear, which is called a snail for its spiral shape. So this snail is covered with many hairs. They pick up the sounds, transmitting signals to the brain. The sensitivity of a person's hearing depends on their condition.. If a person is exposed to a sharp short-term loud sound, the hairs are restored almost immediately. When Noise exposure is regular, then some hairs cease to perform their functions.

There are auditory ossicles inside the ear, they are slightly mobile. And the position is regulated by special muscles. What is it for? Muscles tense when loud, bones turn like this, to protect delicate auditory receptors. If we listen to loud music with headphones for a long time, then these muscles become less sensitive and can no longer fully protect the internal auditory apparatus of a person.

If it is easier to explain the harm of headphones for hearing, hearing aid wears out prematurely. For natural reasons, the body begins to age after 30 years, gradually hearing loss. If you actively use the headset at maximum volume, then this process starts earlier and proceeds faster.

 

One of the diseases is subjective tinnitus., when there is a characteristic ringing in the ears. This is the initial stage of a rapid hearing loss.. And instead of moderate hearing loss after 60 years, man is already 30 loses hearing.

Worse on the hearing organs are high frequencies, so it's better to mute them with an equalizer. Although an hour-long bass pounding is also not the best option, although in general low frequencies are less harmful to the ears.

Symptoms, which should alert:

  • headaches, especially localized near the ears;
  • frequent otitis media;
  • ringing or other noise in the ears;
  • dizziness;
  • jumps in blood pressure;
  • problems with memory and attention;
  • chronic fatigue;
  • nausea not related to food.

Danger of headphones for children

About, How do headphones affect a child's hearing?, in one of his programs, Dr. Komarovsky told. To 10-12 years old children generally do not want to listen to music through a headset. The body is actively growing and shaping, delicate fabrics, any prolonged exposure to loud sound can lead to high frequency hearing loss, when the child does not hear high-pitched sounds. This process is irreversible, can no longer be cured.

In adolescence, you can meet the child halfway and allow him to use the device. To minimize harm from headphones, it is recommended to observe the following rules:

  1. explain to the child, what is a personal device, And don't let anyone else listen to it.. It is also important to clean your ears and the headphones themselves..
  2. Hearing should be checked every 2 of the year.
  3. Maximum allowable volume 60%.
  4. Continuous listening to music no more 1 o'clock.
  5. It is better to choose full-size noise-canceling headphones, they are the safest.
Headphones cause harm not always related to hearing. Often children and adults with earplugs get into accidents., because they do not hear the danger. You should definitely talk about this with your child..

The most harmful and most harmless types of headphones

The effect of ears on hearing varies greatly depending on the type of construction.:

  1. Intracanal or plugs create a seal in the ear canal.
    Therefore the sound, or rather the pressure from him, does not diverge partially in space, and directly hits the eardrum.
  2. Magnetic earpieces, used in exams, generally recommended to be used only in extreme cases and no more 2 hours.
    They are dangerous herbs eardrum, In addition, they are affected by electromagnetic radiation, what is bad for the brain.
  3. Earbuds are one of the safer options, if you control the volume.
    The sound from them does not go inside directly., a is reflected from the channel walls.
  4. False ears are often used at higher volumes, what you need, because there is no sound insulation from the outside world.
    Therefore, long-term use without harm from the headphones is also impossible..
  5. Monitors or over-ear headphones with closed acoustics - the best option.
    They have passive noise cancellation, which is sometimes combined with active. Therefore, there is no need to turn up the volume at full. And the design itself eliminates the aggressive effect on the hearing organs.

Separately, I want to say about wireless devices. Although they do not give such strong radiation, like a phone, but for the duration of use, this fact does not mean anything. Nervousness may appear, insomnia, dizziness and weakness.

It turns out, that over-ear headphones and earbuds are the safest. And the biggest harm of in-ear headphones. This does not mean, that you don't have to buy them at all., just use it less often and more carefully.

Tips for Safe Use:

  • don't use the headset anymore 4 hours a day;
  • take a break every hour;
  • do not turn up the volume more than 60%;
  • do not abuse high-frequency compositions;
  • if negative symptoms appear, consult an otolaryngologist.
