Are Bluetooth headphones dangerous for your health?
Many of us nowadays use our wireless headphones on a daily basis. Nevertheless, it is interesting to look at the question of their impact on our health. Are Bluetooth waves dangerous for our brain? What are the repercussions on our hearing?
Is it dangerous for our health to be exposed to these Bluetooth radiations?
Many scientists have studied the subject, and they are reassuring. 2 certainties have already been established:
- Studies on WIFI have so far shown no danger
- Bluetooth technology is similar to WIFI, but less powerful
Thus, the emission of waves is less strong with Bluetooth, so the potential effects that there could be on the brain, are greatly reduced. The French Federation of Telecoms says that Bluetooth divides by 100 the exposure to waves.
A scientific study has been conducted on Bluetooth and hearing impairment. A group of people were exposed to Bluetooth with headphones, compared to another group not exposed to Bluetooth. Hearing tests were carried out before and after the study on each person. To finally demonstrate that there was no significant difference between the two groups on hearing.
There is no scientific evidence that Bluetooth waves affect hearing. It is a technology that is now used to synchronize smartphones directly to hearing aids, thus helping hearing.
Impact on hearing
There is a real risk of hearing damage if the volume is turned up for too long. This damage can appear in the form of: whistling, buzzing, more commonly known as tinnitus, partial loss of hearing perception. The severity of the damage varies from person to person, depending on medical history, state of fatigue, and the way headphones are used.
The higher the volume, the more frequent and prolonged the listening, the more serious and permanent the damage.
The distance from the sound source, the distribution between low-mid and high frequencies, the recording format, and the quality of the headphones also play a role.
As each individual reacts differently, it is very difficult to establish a table between volume, duration of listening, and types of sounds.
Nevertheless, researchers agree that the higher the volume, the shorter the exposure time must be.
Thus, the WHO, the World Health Organization, advises against using headphones for more than one hour a day at 85 decibels, the sound level of a scream.
Today, all headphones and earphones sold on the market cannot exceed a sound power of 100 decibels, which corresponds to the noise generated by a jackhammer.
