Auditory acclimatization, a short exposure time to strong noise, raises the hearing threshold by more than 10 dB, which can be recovered within a few minutes of leaving the noise environment. Auditory acclimatization is a phenomenon in which a persistent sound stimulus causes a decrease in auditory perception. The auditory system generally to a stable sound source perceptibility in the first 1-2 minutes decreased, and then quickly stabilized at a level, auditory adaptation is characterized by it is a balanced process. The research method of auditory adaptation is the loudness balance method. That is, with a certain sound intensity (such as 80 dB) of pure sound effect on the left ear, with another frequency of the same but variable sound level of the sound at the same time on the right ear, so that the two equal loudness. Then, stop the sound in the right ear and let the left ear continue to listen for 3 minutes. After this acclimatization period, the right and left ears are made equal again, when the equal sound level in the right ear often decreases, e.g., to 60 dB, with an acclimatization volume of 20 dB. Pathological auditory adaptation requires the following examinations: 1. Audiological examination Audiological examination is an examination to understand the state of auditory function and diagnose auditory system diseases by observing the response caused by acoustic stimulation. The purpose is to understand the degree and nature of hearing loss and the location of the lesion. Patients with hearing loss of around 40-50 dB between 1000 and 4000 Hz are not candidates for cochleography. Both sides of the same nature of the ear. 2, CT examination of the ear, nose and throat CT examination of the ear, nose and throat is a method of examination of the ear, nose and throat by CT. Patients are required to remove any contraindicated items from their bodies, lie down on the instrument at the doctor’s request, undergo the examination, and look for pathological features after obtaining the images. 3.Newborn hearing screening Newborn hearing screening is one of the newborn screening programs stipulated by the Ministry of Health. Early screening can enable infants with hearing impairment to be detected at an early stage, diagnosed in a timely manner, treated at an early stage, and promote the development of the infant’s language in the critical period of language learning. The Early Hearing Screening and Intervention Program for Newborns, Infants and Toddlers, which includes hearing screening, diagnosis, intervention, follow-up, rehabilitation training and evaluation of results, is a systematic and socialized eugenic project that requires strict quality control.
