What are the sounds of tinnitus?
Tinnitus is divided into low-frequency tinnitus and high-frequency tinnitus. For example, hissing, squeaking, chirping, or low-pitched roaring, long-term tinnitus can damage hearing.
Tinnitus is a subjective sound experienced by the human ear in the absence of external sound or electrical stimulation. It is worth noting that tinnitus is an illusion that occurs in the auditory system. It is a symptom rather than a disease. Some people often feel some special sounds in their ears, such as buzzing, hissing or sharp whistles, but cannot find the corresponding sound source around them. This situation is called tinnitus.
The first type is physiological tinnitus. Within the body, weak sounds will occur due to blood vessel pulsation, blood flow, muscle contraction, joint movement, breathing movements, etc. Among them, those who are closer to the ear will feel this sound. Usually, because there are strong sounds outside, this weak sound is covered up and not felt. But if you walk into a soundproof room or in a quiet night, you sometimes feel a faint ringing in your ears. This is physiological tinnitus.
The second type is conductive tinnitus. The cause of this kind of tinnitus is obstacles in the conductive part of the auditory system, such as swelling and blockage of the external auditory canal, perforation of the tympanic membrane, invagination, inflammation of the middle ear, adhesions, and sclerosis, etc. Sound transmission disorder reduces the ability to hear external sounds and weakens its function of masking sounds occurring in the body, allowing them to be felt and become tinnitus.
Furthermore, the sound transmitted into the ear through bone conduction, due to conduction barriers, the outward escape channel is blocked, which improves the feeling of sound in the ear and becomes a A whirring sound that is mainly low-frequency, like the wind. We can try it ourselves. Cover our ears with one hand and feel a roaring sound in our ears. This is typical conductive tinnitus.
Tinnitus makes people upset and restless. In severe cases, it can affect normal life and work. Tinnitus can occur in a variety of diseases, and almost any cause of ear disease can lead to symptoms of tinnitus, but the relationship with hearing is complex. Tinnitus may be caused by just a small piece of eardrum touching the eardrum, but it may also be caused by a tumor on the auditory nerve.
