  • Preparations for fine-tuning

The hearing aid professional shall enter the following data in the fitting system from the manufacturer:

⎯ data from the audiological assessment;

⎯ data from the hearing profile;

⎯ properties of acoustic coupling (e.g. ear-mould).

Based on this data, a pre-setting shall be programmed into the hearing aid to be the starting point for the fine-tuning of the fitting.

hearing aid provision process20

  • Fine-tuning of hearing aids
    • ..verify the proper physical fit. If the fit is not accepted the custom ear-mould/shell shall be modified until proper fit is achieved.
    • The hearing aid is fine-tuned in close interaction with the client until a setting, accepted by the client, has been reached.
    • In cases where an acceptable fitting is not easily obtained, additional surveys shall be carried out to identify the ways to improve the fitting. If real-ear measurements are performed they shall follow ISO 12124.
    • … the fine-tuning procedure shall be repeated for all programs, considering the specific listening situations for which they are intended to be used.
hearing aid provision process21

  • Verification of fitting

To verify that a proper fitting has been achieved, to test for improvement in hearing ability.

It shall be assured that no discomfort is created in particularly loud situations. The client shall be exposed to situations that likely will be part of the client’s everyday life in accordance with the hearing profile.

Verification of improvement in hearing ability should be assessed in multiple ways. At least one of these shall be used and the results reviewed with the client:

hearing aid provision process22
Hearing aid provision process

- speech audiometry in sound field with and without noise, aided compared to unaided, following the procedure specified in EN ISO 8253-3;

⎯ surveys with real-ear measurements to verify that the response achieved matches the proposed fitting target, following the procedure specified in ISO 12124. Client preferences may result in deviations from the proposed target;

⎯ questionnaire concerning the perceived benefit of the hearing system. The questions may refer to before and after fitting or focus directly on perceived benefit. A scientifically validated questionnaire should be used, and the client should have at least several weeks of everyday experience with the hearing system;
