If you are more concerned with helping customers solve their problems, then you may be on the road to a fitter. It is necessary to know whether the selected hearing aid can solve the problem that the customer listens to. The hearing aid verification (assessment) is an indispensable task.
Referring to the evaluation of hearing aid effects, the fitter must know that there are four main methods, hearing aid threshold, true ear test, speech test, and questionnaire survey. The hearing aid threshold is subjective quantitative assessment. The true ear test belongs to the objective quantitative evaluation. The speech test belongs to the subjective function evaluation. The questionnaire evaluation has multiple effects or satisfaction evaluation. These evaluation methods can evaluate the effect of the customer’s hearing aid from one side, each has its own advantages and cannot be replaced by each other. The real ear test evaluation is subject to hardware limitations (the price of real ear analysis instruments is relatively high). At present, only a few fitting institutions in China have relevant instruments to evaluate, most of the fitting institutions have no application, and the application of the other three evaluation methods Relatively less constrained by hardware.
