Recent research has shown that speech is most intelligible for hearing-impaired individuals when it is amplified to a comfortable level in specific frequency regions between 250 and 6,000 Hz, and is limited below the discomfort level. If commercial hearing aids and earmold coupling are adjusted appropriately, they will provide amplified sound within these parameters for most hearing-impaired individuals. A clinical procedure is described 1) to preselect an aid and earmold with the approximate electroacoustic characteristics that are needed, 2) to determine the gain actually provided by this hearing aid/earmold combination, and 3) to adjust the hearing aid and/or earmold if the gain and maximum output do not meet the prescribed criteria, or if the wearer finds the sound quality unacceptable.
最近的研究表明，对于听力受损者而言，当语音在250至6000赫兹的特定频率区域内被放大到舒适水平，并限制在不适水平以下时，其清晰度最高。如果商业助听器和耳模耦合得到适当调整，它们将为大多数听力受损者在这些参数范围内提供放大的声音。本文描述了一种临床程序：1）预先选择具有所需近似电声特性的助听器和耳模；2）确定该助听器/耳模组合实际提供的增益；3）如果增益和最大输出不符合规定标准，或者佩戴者发现音质不可接受，则调整助听器和/或耳模。
