Recent statistics show an increased demand for various types of headphones. The findings of experts based on studies in the Moscow metro confirm that 80% of users of portable mobile devices constantly listen to music while in transport. Regarding the calculations of previous years, the number of people using such gadgets has tripled.
Such calculations are confirmed at the sight of young people in the gym, library and simply - on the street. The number of manufactured accessories for listening to audio recordings is growing every year. Earlier, in addition to music, headphones made it possible to hear some loud environmental sounds, but modern models isolate the user from everything that happens around.
Are earphones harmful to health
Researchers have found that over the past 10 years, there has been an increase in the number of young people who have hearing loss after 30 years, as was typical for pensioners after 60 years. Experts attribute this trend to the use of headphones, and doctors have proven their detrimental effect on the hearing organs. At the same time, no one says that the headphones can be deaf.
Using accessories for periodic telephone conversations or language learning does not harm the auricles. Problems arise when listening to music, especially when the volume is over 100 dB. And teens love to listen to their favorite tunes, increasing the sound, often worsening the playback quality of the musical composition.
ATTENTION! Headphone users, by the nature of their professional activity, suffer less from hearing impairment. Dispatchers, radio operators use this accessory periodically, and do not use it at maximum power.
For the human ear, sound perception at 30 dB is considered normal. The operation of technological equipment, screaming, vehicle noise, which exceeds 80 dB, is considered harmful to the hearing organs. This level corresponds to the noise in the subway. And the headphones give out directly to the auricle up to 120 dB, which corresponds to the volume of the jet engine, measured at a distance of 50 meters.
REFERENCE! In accordance with labor protection requirements, drivers of ground and underground rail transport must use ear plugs, a device that isolates the auricle from noise. They look like earbuds but are designed to protect your hearing only.
In addition to the ears, as doctors have shown, the entire human body suffers. The main symptoms of this effect are:
- dizziness;
- fast fatiguability;
- nervousness;
- tinnitus;
- headaches;
- pressure surges.
Scientists have proven that the use of accessories for listening to loud music leads to complete hearing loss. Modern adolescents use gadgets for this purpose, without thinking about the consequences to which it will lead.
The most harmful and most harmless headphones
Manufacturers of accessories for mobile devices offer users a wide selection of acoustic devices for listening to audio recordings. These include:
- loose leaves or vacuum;
- pills;
- invoices;
- monitoring.
By fixing the vacuum gadgets in the auricle with a silicone or rubber seal, the user isolates himself from external sounds. Fluctuations in the waves that are transmitted directly to the eardrum cause great damage to the auditory organ. According to experts of audiologists, when using such headphones for more than 5 years, pathological painful processes become irreversible and lead to hearing loss, therefore such accessories are considered the most dangerous.
The average owner of a mobile device uses tablets, which are often included in the package of phones. A special design directs sound to the eardrum, reflected from the walls of the hearing organs, reducing the load on perception. Weak soundproofing does not allow to obtain good quality reproducible recordings, while having less harmful effect when using.
Overhead gadgets are pressed to the ears thanks to the bow, which is placed on top of the head or on the back of the head. There is less harm from them than from loose leaves, and quality does not always suit users.
Monitoring headphones are completely, and some models partially cover the ears from the external environment. Such models are used for professional need for work or music lovers. It is generally accepted that this type of accessory does less harm to the hearing organs, as passing through the surface of the auricle, vibrational vibrations are softened and the eardrum perceives music painlessly.
IMPORTANT! When choosing any of these accessories, you must remember that each of them is capable, to a greater or lesser extent, of harming the hearing.
Does high volume harm your ears?
Researches by scientists have shown that rock music lovers listen to recordings while increasing the sound in their headphones to 90-130 dB, while receiving positive emotions. It is this use of accessories that leads music lovers to hearing impairment.
At first, the pauses between listening to music at such a volume allow the auditory functions to be restored during the day. But, over time, with the frequent use of gadgets, the quality of perception of surrounding sounds - deteriorates. Therefore, audiologists recommend the use of accessories only at an average or low level of sound vibrations.
The small distance from the sound source to the eardrum increases the risk of hearing loss. Experts investigated the influence of various models of accessories and argue that vacuum gadgets can be used no more than 1 hour per day. Overhead and tablets - no more than 3 hours.
When using monitoring headphones professionally, you must try to remove them more often. Listening to music using such an accessory should not exceed 4 hours per day.
Having studied the features of the harmful effects of modern gadgets on human health, acquiring headphones, they are used only when necessary. It is also important to remember that using such an accessory on the street or in transport, the perception of the environment becomes inferior and you can easily become a victim of circumstances that can be avoided by using the gadget only in a safe environment.
