A qualified hearing aid fitting is only possible if the ENT doctor not only prescribes the device, but also conscientiously checks the comparative adjustments made by the hearing aid acoustician. In deciding, which of the tested hearing aids achieves the best and most appropriate improvement of hearing, the physician should first thoroughly study the acoustician's fitting protocol, which contains comparative results of all devices tested. The subjective satisfaction of the patient with his hearing aid can be determined in a detailed conversation or with a special questionnaire. The examination of the otoplastic is as necessary as the improvement of speech discrimination under free field conditions, especially with additional noise. With in situ measurement, the individual transmission characteristics of the hearing aid and the otoplastic are tested in a few minutes. Conscientious control of the fitted hearing aid is only possible with loudness scaling. The scaling function shows clearly whether the fitted aid has adequate amplification, is not too loudly adjusted, and whether the field of pleasant hearing has been considered.
只有当耳鼻喉科医生不仅开具助听器处方，还认真检查助听器声学专家所做的对比调试时，才能进行合格的助听器验配。在决定哪种测试过的助听器能实现最佳且最合适的听力改善时，医生应首先全面研究声学专家的验配方案，该方案包含所有测试设备的对比结果。患者对其助听器的主观满意度可通过详细交谈或特殊问卷来确定。耳模检查与在自由声场条件下，尤其是有额外噪音时语音辨别能力的提高一样必要。通过原位测量，只需几分钟就能测试助听器和耳模的个体传输特性。只有通过响度缩放，才能认真控制已验配的助听器。缩放功能能清楚显示已验配的助听器是否有足够的放大功能、调节音量是否过大，以及是否考虑了舒适聆听范围。
