In cases of deafness and tinnitus in humans, hospitals will do electrical audiometry and acoustic impedance tests. Bilateral tympanic chamber type A is usually the result of the tympanic chamber curve. The human body is divided into type A, AS, AD, B and C tympanic chamber curve shaping examinations. Bilateral tympanic chamber type A means good tympanic membrane motion, no fluid and edema in the tympanic cavity, usually hearing loss means deafness caused by cochlear hearing nerve lesion, tympanic chamber type B usually means fluid in the tympanic cavity, and bilateral tympanic chamber type C means the eustachian tube is not functioning. Therefore, clinically, the tympanic chamber profile can be used to initially determine which condition of deafness a patient has and to clarify the cause of the deafness in order to target treatment.
