Noise deafness is relatively common in clinical practice and patients often have a long history of noise exposure prior to the disease. It is caused by extremely poor hearing in crowded and noisy markets, and is often preceded by a history of machine rumbling, chainsawing, and long-term exposure to headphones. The diagnostic criteria for the disease clinically are that the patient performs a hearing examination with binaural high-frequency hearing at 4000-8000 Hz, a significant decrease in the hearing curve, and a consistent decrease in the air-bone conduction hearing curve, but normal low-frequency hearing. During the acoustic impedance and stapedial muscle reflex examination, the acoustic impedance curve was A-shaped, and the stapedial muscle reflex was significantly attenuated. At the same time, the patient’s tympanic membrane was examined without obvious congestion and perforation. With the above indications, noise deafness can be diagnosed.
