What is hearing loss?

Patients with hearing loss often have these subjective feelings:

(1The sound that was originally heard can’t be heard now, such as the ticking of a watch;

(2I feel that the voices of people around me are small and cannot be heard clearly;

(3) one ear does not hear the other ear;

(4I can hear the voice of their speech, but I can’t understand the content of the speech and so on. These complaints can all reflect a situation: the patient’s hearing sensitivity may have decreased, but is there really hearing loss?


To determine if there is hearing loss, a most routine hearing test is required, which is “pure tone threshold measurement” to obtain the frequencies of the patient’s ears (250,500,1k,2k,4k,8kHzThe hearing threshold (the minimum sound intensity that can be heard) and the patient’s hearing loss is assessed by comparison with normal young people’s data. If the patient has a single ear and/Or both ears in the speech frequency segment (500,1k,2kAnd4kHzThe average pure tone hearing threshold is greater than the normal standard (adult normal hearing in adults)25dB HLChildren15dB HLWithin, the smaller the value, the better the hearing, the perceived loss of hearing.
