Always wear Bluetooth headphones, beware of otitis media

“My ears are buzzing and my head hurts a little.” At about ten o’clock this morning, a middle-aged man hurried into the outpatient department of the otolaryngology department of Hangzhou hospital of traditional Chinese medicine with his face on his side and one ear covered.

The middle-aged man told the doctor that his surname was Xu. He was 40 years old and a taxi driver. He was driving this morning. After receiving a call with his Bluetooth headset, he suddenly found that his right ear was buzzing. “The sound keeps making me dizzy.” Master Xu thought it was dangerous to do business like this, so he went directly to the otolaryngology outpatient department of the hospital to have a look.

The otolaryngologist carried out relevant tests on Mr. Xu’s ear canal and hearing, and found that Mr. Xu’s hearing was worse than that of normal people.

“I had otitis media before, and my hearing is not very good.” Master Xu on the other side said with a red face that he was using the new Bluetooth headset this time. “The new traffic regulations explicitly prohibit drivers from receiving and making calls while driving. I think that I always have to make and receive calls when I am on the road. So I bought a Bluetooth headset online. It is very cheap. I guess the quality is not very good.”

Master Xu also told the doctor that he had just answered a phone. When he got through, the earphone made a loud and harsh noise. Then his ears began to feel uncomfortable.

Therefore, the doctor suggested that Mr. Xu had better not wear Bluetooth earphones on the premise that he had heard the decline.

“This is actually the same as hearing loss caused by listening to earphones for a long time.” Chen Zhiling, deputy director of the otolaryngology department of the Municipal Hospital of traditional Chinese medicine, said that although Bluetooth earphones are light and convenient, wearing them for a long time is also harmful to health. When many people choose earphones, they will choose products with loud and clear sound. The audio frequency of ordinary people’s speech is about 500-2000 Hz. If it is too high or too low, it will have certain adverse effects on the ears. If the people buy inferior earphones, sometimes in the process of unsuccessful docking, the earphones may suddenly produce harsh and sharp sounds, which is easy to damage the cochlear sensory nerve, and in serious cases, tinnitus and other symptoms may occur. If not handled properly, it may induce external ear diseases and even sensorineural deafness. Secondly, no matter how light the earphone is, if it is hung on the auricle for a long time, it will compress the auricle and easily cause local crush injury of the auricle. If you are stimulated by the cold when you go out, it is easy to induce ear inflammation. Another point is that if you wear Bluetooth earphones while driving, one ear will be blocked by the earphones, and the hearing function of the other ear will certainly be affected. If you make a phone call while driving, you may lose your attention due to talking with others, which is a potential safety hazard.

Dr. Chen suggested that when you wear a Bluetooth headset to receive and make calls, the volume should be controlled to hear others. Wear Bluetooth headset for a long time. You can wear it on the car and take it off when you get off. Since the hearing organs of teenagers are not yet mature, it is recommended not to use Bluetooth earphones or wired earphones. If you have to use it, you’d better choose one produced by a regular manufacturer.
