Technical Field

[0001] This utility model relates to the field of otological hearing testing technology, and in particular to a hearing testing aid. Background Technology

[0002] Hearing tests primarily examine the degree of your hearing loss. It is a subjective value, which is the minimum decibel level at which you can hear different frequencies of sound. Air conduction and bone conduction values ​​can determine the nature of your hearing loss, such as sensorineural, conductive, or mixed hearing loss. It is a diagnostic method that understands the state of hearing function and auditory system diseases by observing the examinee's response to sound stimuli.

[0003] In existing technologies, some devices cannot effectively adjust according to the user's head circumference, resulting in a poor user experience during testing. This can easily lead to users moving around during testing, affecting the test results.
