Hearing loss, deafness due to abuse of bluetooth headsets

Associate Professor Nguyen Hoai An shared about headphones that affect hearing.

Mr. Do The Hai (31 years old, from Thai Binh province) went to the doctor for examination because of the recent time, Mr. Hai often feels pain in the ear, there is a roaring noise in the ear and when he does not sleep well .

Mr. Hai shared, for over 2 years now, he has chosen bluetooth headsets because of its utility and fashion effects. Bluetooth headset helps you to listen to the phone, listen to music, watch movies without worrying about being stuck with the cord.

During the examination, the audiologist said that Mr. Hai due to his habit of abusing Bluetooth headsets too much. Every day, Mr. Hai wears headphones for 4 to 5 hours. This has damaged the ear nerves, the blood vessels in the ear are affecting the brain function causing discomfort, insomnia.

The doctor had endoscopy but the eardrum was not damaged. When a hearing test was performed, it was determined that the patient with impaired hearing function and deafness received on both sides.

According to Assoc. Prof. Nguyen Hoai An, Head of the Department of Otolaryngology – An Viet General Hospital, bluetooth headsets are smart devices and a trend of science and technology development. Using moderate headphones does not affect hearing, but hearing at 85 decibels (dB) affects hearing.

Bluetooth headsets have good soundproofing conditions, but the sound is high and it affects the organs of the inner ear. Therefore, those who work in noisy environment for a long time, the negative trauma in patients with unknown symptoms.

According to Dr. An, usually they only see symptoms of fatigue, loss of appetite, a sense of bees’ mind, some people may hangover … Most of them are unaware that their hearing is declining, things happen slowly and they don’t realize, the feeling of hearing is getting worse, the communication is also limited. Only when people say it louder, turn on the TV to be louder to hear it.

Dr. An said that hearing loss due to sound effects will often be symmetrical on both sides of the ear, due to inflammation of only 1 ear; wearing a bluetooth headset and making loud sounds will cause binaural deafness, and this deafness is irreversible deafness.

The mechanism that leads to the use of bluetooth headphones or regular headphones if listening everyday with high intensity and loud sound intensity will be increasingly harmful. Harm will increase in decibels. For example, at 85dB or 90dB, the hearing loss is getting more and more. Listening continuously for 2 hours will cause more severe injuries. The biggest consequence of wearing headphones is a negative injury.

Dr. An thinks that the headset should be worn for about 30 minutes to 1 hour of rest, if listening too much about 5-6 hours with high sound intensity, the ear organs will surely be damaged and lasted for a long time. May monthly, yearly. The coocti organ of the ear (containing the hearing analytical cells) was deeply damaged.

The treatment is not possible, even the use of drugs does not work. Therefore, Dr. An said that if people who have the habit of abusing headphones need to change immediately: Should wear in a short time with rest, listen with just enough sound; It is also not advisable for children to listen loudly because it can become a habit of listening to loud sounds that will damage their ears.
