Only a handful of people have the ability to cause tinnitus on their own will

Hearing, one of the five senses of humans, is composed of a very delicate and complex system, and abnormalities in this system can cause symptoms such as tinnitus and hearing loss. However, on rare occasions, there are people who can cause this tinnitus on their own will, Science Alert of science news media explains the mechanism.

Some People Can Make a Roaring Sound in Their Ears Just by Tensing a Muscle

You can move the skeletal muscles to move the human skeleton at your own will, but there are a few that are difficult to move at your own will. One of them is the tympanic tensor in the middle ear.

When we hear something, the sound becomes vibrations of the air and travels to the eardrum deep inside the ear canal (the ear canal). Vibration is transmitted from the eardrum to the inner ear through three types of ossicles: stapes, kinuta and hammer bones, where the vibrations are converted into electrical signals and transmitted to the brain.

The tympanic tensor is one of the ossicles and closest to the eardrum Hammer ( soil ) It is a skeletal muscle attached to the bone and the cartilage of the

Eustachian tube. Relaxation ( Tangerine ) By doing so, it plays a role in adjusting the tension of the eardrum according to the loudness of the sound. When the tympanic muscles contract, the tibial bones increase the tension of the eardrum, making it difficult for the eardrum to vibrate, reducing the vibration transmitted to the inner ear, and making it difficult to hear sound.

Therefore, the tympanic tensor muscle plays the role of 'protecting the inner ear from being damaged by loud sounds by contracting reflexively in response to loud sounds'. For example, if you listen to the explosion in a live house and then go outside, you may hear the surrounding sounds quieter. This is because it is difficult for the eardrum to pick up sound due to contraction of the tympanic muscle.

For most people, the tympanic tensor muscle cannot be moved on its own. However, there are very few people who can move this tympanic tensor muscle on their own, and when you contract the tympanic tensor muscle, it feels like a low sound like `` gogogogogo '' thunder roars in your head And that. This 'tinnitus that can be caused by one's own will' is said to be mentioned in a 19th century medical book.

In other words, tinnitus heard by a person who can contract the tympanic muscle is literally the sound of their muscles pulling the eardrum. According to a 2013 case report , a 27-year-old man who complained to a doctor that tinnitus might occur in his left and right eyes if he found that he could actually contract both tympanic tensor muscles spontaneously.

In addition, something Bite ( Or ) The `` sounds generated from your body '' can be heard well by vibrating your body by actions such as mumming, coughing, yawning, so that your body will not lose your hearing due to hearing loss The tensor is slightly contracted. Thus, Tinnitus caused by contracting the tympanic tensor muscles can be experienced when yawning, according to Science Alert.
