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, very rarely, there are people who can cause this tinnitus on their own will, Science News media Science Alert explains the mechanism.
Some People Can Make a Roaring Sound in Their Ears Just by Tensing a Muscle
When we hear something, the sound becomes the vibration of the air and is deep inside the ear canal (the ear canal)eardrumIt is transmitted to. And the vibration is from the eardrum to the three types of stapes,OssiclesIs transmitted to the inner ear through which the vibrations are converted into electrical signals and transmitted to the brain.

Tympanic tensorHammerBoneWhenEar canalSkeletal muscle attached to the cartilage.RelaxationBy doing so, it plays a role in adjusting the tension of the eardrum according to the loudness of the sound. When the tympanic muscle contracts, 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 a 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 at 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.
A part of the human population can voluntarily control the tensor tympani, a muscle within the ear.Contracting this muscle produces vibration and sound.The sound is usually described as a rumbling sound https://t.co/FjD36qFACU pic.twitter.com/ianKb60EK8

In other words, tinnitus heard by a person who can contract the tympanic muscle is literally the sound of their muscles pulling the eardrum. 2013Case reportsThen, a 27-year-old man who complained to a doctor that tinnitus sounds in his left and right eyes when he thought about it was found that he was actually able to contract both tympanic tensor muscles spontaneously.
In addition, somethingBiteThe “ 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.
