Are wireless headphones harmful? Expert material

Strictly speaking, any headphones are harmful. Wired, Bluetooth. IR radio frequency, monitor, overhead, “gags”, “droplets” … Any such devices exert undesired sound pressure on eardrum and form attractive for development bacteria environment in the outer ear.

Therefore, it is recommended to use the headphones not constantly and not on full volume. Otherwise, hearing impairment may well be experienced. or otitis media (or similar bacterial inflammation).

However, the question “Are wireless headphones harmful?” implies a little different – are they more harmful to everyone else? Let’s try this sort out.

How can wireless headphones be harmful?

With sound pressure on the eardrum and creating sealed, moist and warm environment in the outer ear, attractive for the development of bacteria and bacterial infections, sorted out. Now the turn of the radio signal.

Wireless headphones – it is worth mentioning that now we will talk about models with Bluetooth and a radio frequency of 2.4 GHz – for communication use a radio signal with a smartphone or computer. However its special frequency and digital transmission on it specify interface. So, bluetooth headphones use the most the frequency common in civilian close communications is 2.4 GHz.

At a frequency of 2.4 GHz broadcasts almost everything. Emit it Wi-Fi routers and computer mice without cable, cordless phones and microwaves. Bluetooth also uses a frequency of 2.4 GHz. IN As a result, a lot of equipment around the user emits at 2.4 GHz, creating streams of energy.

So, if the author of this article was in an open field with full with a set of his EDC, he would still have five emitting at 2.4 GHz devices – smartphone, laptop, bluetooth mouse, clock and wireless headphones.

Active distribution of wireless devices leads to the so-called “electromagnetic pollution”. AND There are standards for this case! Namely – SanPiN 2.2.4 /, which describes the maximum permissible harmless value of energy flow at a frequency of 2.4 GHz. It is 200 μW / cm2 × h.

Average power density from wireless headphones with Bluetooth is 1.6 μW / cm2 × h. It is not just very few. To make the wireless headphones harm in some way, you will have to put them on yourself in an amount of at least 150 pairs. Unlikely Does anyone have so many ears …

Stop! Microwaves and wireless headphones use one frequency!

One of the important arguments of supporters of the idea of ​​harm electromagnetic pollution from BT and Wi-Fi is a statement that microwave ovens and bluetooth use the same frequency – 2.4 GHz. And it is true. And microwave ovens fry all living things, which it appears in them.

There is only one “but” – power. Let’s draw an analogy. IN hospitals often use physiotherapy to treat various muscle diseases – electrodes are connected to the patient and they begin to beat him electric current. Not only does this happen voluntarily, but also helps! So – is the current useful? And if you put your fingers in the socket, then can be cured of everything in general?

No matter how. A current with high power is quite capable of “frying” person.

Similarly with the “magic 2.4 gigahertz.” In the microwave is very powerful transmitter, at 600-800 watts. On the phone or laptop these 600 watts can not be found, there would at least reach 100 μW … Therefore, the radiation from the phone, laptop, wireless headphones, Wi-Fi routers or mice are not dangerous there.


Wireless headphones are no more harmful than any other. AND, as with other types, it is important to maintain good hygiene. Not use audio equipment at very high volume, do not wear it on the head for more than an hour without a break.

It’s also worth considering that the monitor or “overhead” models are slightly less harmful than intra-channel ones. Last reliable clog the ear canal and direct the sound stream directly to the long-suffering eardrum. Monitor the same models provide less tightness of the organs of the external ear and at the same volume create less sound pressure on internal organs of hearing.

And, of course, headphones need to be removed during the transition roads – rail or road – and while in public places or hazardous areas.
