Sensitivity to sound is a sign of auditory hypersensitivity. Causes of auditory hypersensitivity include recent sudden onset of tinnitus, stress, exertion, acute acoustic injury, and long-term exposure to noise. Auditory allergy is associated with a number of diseases, such as tinnitus, Meniere’s disease, autism, migraine, depression, abnormal thyroid function, Lyme disease, etc. There is no complete treatment for auditory hypersensitivity. The main principles of treatment are to actively treat the primary cause, avoid excessive ear care and gradually reduce the ear’s sensitivity to sound. Many patients want to escape from all sounds in the environment and often use ear plugs and earmuffs to avoid sound disturbances in their daily lives and to keep them in a very quiet environment. This situation is very likely to lead to convulsions and aggravation of allergy symptoms, so it is recommended not to use ear plugs and other protection for sounds below 65 decibels. In addition, gradually reduce the ear’s sensitivity to sound, you can gradually help desensitize through a variety of sounds. Pink noise is generally 200-6000Hz, which is the most common noise in nature and can be a better choice.
