The hazards of wearing bluetooth over ear headphones often
We often see people in the morning exercises listening to the radio with earplugs, and students can also be seen walking or riding bicycles while listening to music on campus. I saw young people on the bus listening to rock music so loudly that even the neighbors could hear the sound. Such long-term use of bluetooth over ear headphonescan cause noise-induced hearing loss.
Chinese scientific and technological personnel have conducted research and found that there is a significant difference in hearing threshold between subjects with an average age of 23 years old who use bluetooth over ear headphones for 1 hour and 1-2.5 hours a day compared with the control group. He suggested that the use of earbud headphones can lead to noise-induced hearing loss, especially in the high frequency range above 4000 Hz, which is significantly larger than the low frequency range. The longer you use earbud headphones, the more severe your hearing loss. Some scholars have also reported that often in a noisy environment can cause 4000 Hz hearing loss first.
There are cochlear organs in people's inner ears. Scholars believe that due to long-term excessive stimulation, cell and tissue metabolism disorder, blood supply and oxygen supply are insufficient, the peripheral receptors are damaged, leading to noise-induced hearing loss.
Remind everyone that if you have high-pitched tinnitus (such as cicadas, siren, metal sounds, etc.), you need to go to the hospital's ENT department for examination and treatment, which is very important to prevent deafness.
It is recommended to use earbud headphones for a long time and high volume to prevent noise-induced hearing loss.
In some young people who wear bluetooth over ear headphones to listen to music, hearing loss is increasing. This is because after a person puts on the bluetooth over ear headphones, the external auditory meatus is tightly blocked by the bluetooth over ear headphones. High-volume audio sound pressure will directly enter the ear and damage hearing, causing irreversible hearing damage.
If you listen to music with bluetooth over ear headphones for a long time, your sense of hearing will be fatigued and damaged, causing hearing loss. The human body will experience irritability, dizziness, insomnia, memory loss, inattention, slow thinking, abnormal mental disorders, etc., which is good for your health. Very harmful.
For this reason, when listening to music with headphones, you should pay attention to reducing the volume, soft and not harsh, and do not listen to it continuously for a long time. Relevant experts recommend that adults should use headphones for no more than 3 to 4 hours a day, and teenagers should not use bluetooth over ear headphones for more than 1 to 2 hours a day because the auditory organs are not mature. Intermittent listening is appropriate.
