What's the reason for the ear murmur?

summary

Tinnitus is the sound that people's ears feel subjectively without the stimulation of external sound waves. In other words, tinnitus is an illusion of the auditory system, a symptom rather than a disease. Some people often feel that there are bees, mosquitoes and other insects flying around in their ears, which is called tinnitus. What's the reason for the ear murmur? Let's talk about it

What's the reason for the ear murmur?

First, physiological tinnitus. In the body, blood vessel pulsation, blood flow, muscle contraction, joint activity, breathing movement, etc. will produce weak sound, which will be felt by those close to the ear. Usually, because there is a strong sound from the outside world, this weak sound is covered up, but not felt. But if you walk into the sound insulation room or in a quiet night, sometimes you will feel a weak sound in your ears, which is physiological tinnitus.

Second, conductive tinnitus. The cause of this tinnitus is that the conduction part of the auditory system is obstructed, such as swelling, blockage, perforation of tympanic membrane, invagination, middle ear inflammation, adhesion, sclerosis, etc. The transmission obstacle reduces the ability to listen to the outside sound, weakens its function of covering up the sound in the body, so that it can feel it, and becomes tinnitus. In addition, the sound transmitted into the ear through bone conduction is blocked in the outward escape channel due to the conduction barrier, which improves the feeling of the sound in the ear and becomes a kind of whistling sound with low frequency as the main frequency and like wind. We can try it ourselves. When we cover our ears with one hand, we can feel the roaring sound in our ears. This is the typical conductive tinnitus.

Third, nervous tinnitus. The reason is that the sensorineural part of the auditory system is impaired. When the inner ear auditory receptor is sick, such as drug poisoning, noise trauma, Meniere's disease, etc; The auditory nerve and auditory center suffer from trauma or inflammation, poisoning, ischemia, tumor, etc; Tinnitus occurs when various intracranial lesions affect the auditory nerve or auditory center. This kind of tinnitus is mostly high frequency cicada or harsh sharp sound.
