Description

TECHNICAL FIELD

[0001] The present application relates to the field of hearing aids, in particular to a method for adjusting the output limit of a hearing aid. BACKGROUND

[0002] A hearing aid is a tool, device, apparatus and instrument used by hearing-impaired people to compensate for the defects caused by hearing impairment and to improve their communication ability. When wearing a hearing aid, the appropriate product for the patient should be selected according to the electro-acoustic characteristics of the hearing aid, the relationship between the hearing characteristics and the hearing needs of the patient. After wearing the hearing aid, it is best to get used to various background sounds in a quiet environment and try to distinguish each sound.

[0003] Hearing-impaired people as a special group are faced with the problems of communication difficulties and reduced quality of life. The emergence of hearing aids has brought hope to this group. However, the traditional hearing aid adjustment method often cannot balance the amplification effect and user comfort. On the one hand, due to the inability to accurately control the output amplitude, the user may feel that the sound is too loud in a noisy environment, causing discomfort. On the other hand, long-term exposure to high volume may cause damage to the user's remaining hearing. The hearing aid can only adjust the output according to the low, medium and high settings set by itself. Such output adjustment method has limitations. Not every patient's hearing loss is in the same interval. Long-term inconsistent hearing frequency can damage hearing. It cannot be adjusted according to the external environment, and the flexibility is low. Therefore, it is necessary to propose a method for adjusting the output limit of a hearing aid. SUMMARY
