Full-digital hearing aid and non-traditional hearing aid fitting method

Abstract

The invention discloses a full-digital hearing aid which comprises a digital signal processor. In the digital signal processor, at least two hearing compensation prescription modes undergoing corresponding hearing aid parameter programming or non-linear signal processing are preset according to typical non-linear hearing loss graph types of a target patient suffering from hearing impairment. The patient suffering from hearing impairment does not need special fitting services of a traditional digital hearing aid, can directly wear the hearing aid, chooses one hearing compensation prescription mode suitable for the hearing loss type and the hearing loss degree of the patient suffering from hearing impairment, adjusts volume in the hearing compensation prescription mode, experiences the hearing compensation effect according to self feeling, and can choose the hearing compensation mode and the volume, wherein the special fitting services of the traditional digital hearing aid include but are not limited to hearing tests and hearing aid programming and debugging. The full-digital hearing aid can meet the requirement for fitting of the patient suffering from hearing impairment and is wide in application range. The invention further discloses a hearing aid fitting method.

Description

technical field [0001] The invention relates to a digital hearing aid, in particular to a brand new digital hearing aid which changes the traditional hearing aid fitting mode, and a brand new digital hearing aid fitting method. Background technique [0002] Traditional digital hearing aids (digital hearing aids) personalized fitting (fitting) involves nonlinear signal processing for nonlinear patient hearing curves. The operation process is as follows: [0003] · Hearing-impaired patients must first undergo a hearing test (hearing test) with a professional audiometer (audiometer) and other testing instruments in a silent environment in the hearing test room of the hospital or in the quiet room of a professional fitting shop outside the hospital, and then get the test Results - printed audiogram (audiogram); [0004] · A professional audiologist (audiologist) or dispenser (dispenser) selects the type of hearing aid according to the patient's condition; [0005] · Connect th...

AI Technical Summary

Problems solved by technology

[0009] The above steps are completed by more than two sets of independent instruments and equipment, and are operated by more than one professional; the technical level and quality of audiometry and fitting completely depend on independent operating professionals, and cannot be monitored and guided;

[0010] It is completely a traditional manual independent work mode, which takes a long time, costs a lot of money, has many human uncertainties, is inaccurate, deviates from reality, and the equipment is expensive and bulky; the service can only be obtained in hospitals or fitting shops with better equipment. , it is not easy to walk into communities and families; it cannot be sold in chain drugstores with very limited equipment and technical services in the community; it is difficult to use the Internet for online sales; therefore, most patients cannot enjoy it because professional services cannot keep up and the price is expensive.
