How to debug the digital hearing aid to reach the best state

Digital hearing aid is different from analog hearing aid. It uses non-linear amplification circuit to convert voice signal into digital signal. According to the hearing needs of patients, it processes digital voice signal through various digital signal processing methods.

Digital hearing aids can automatically match the amplification strength of different frequencies of sound according to the external environment and the hearing loss situation of users. However, each hearing loss patient must have different feelings about the sound, so the hearing aids need to be debugged many times. No one can make users very satisfied after debugging once.

So how to debug the hearing aid to the best state?

To achieve the best state, it is not only determined by the performance of the hearing aid and your needs for the hearing aid. For the same patient, in different environments, the recognition of voice is also different, for example, the same 60 decibel speech sound. In a quiet office, and a noisy food market, what he hears is certainly different for the patient, even in a quiet office You may not be able to hear clearly in a noisy environment.

Therefore, for users, during the wearing process, they need to go to the fitting center for debugging many times. At the same time, they need to write down the problems found during each wearing or their own listening situation, and then they can tell the fitting examiner when debugging, so that the fitting examiner can have more ideas during debugging, which can be achieved after multiple debugging A perfect fit.
