The perceptual consequence of venting an earmould while maintaining the insertion gain at a preferred listening level was examined on nine hearing-impaired individuals with bilaterally symmetrical sloping sensorineural hearing loss. Subjects wore binaural programmable hearing aids and selected their preferred insertion gain while the hearing aids were coupled to vented (2.2 mm parallel vent) and unvented earmoulds. A modified Simplex procedure with discourse passages presented in quiet was used to determine preferred insertion gain. The results showed that venting enhanced subjects' quality rating of the hearing aids during listening and vocalization tasks, but did not change subjects' word recognition scores. These results suggest that vented earmoulds should be used to achieve target insertion gain in order to maximize patients' acceptance of hearing aids.
在9名患有双侧对称斜坡型感音神经性听力损失的听力受损个体中，研究了在将插入增益维持在偏好聆听水平的同时对耳模进行通气的感知结果。受试者佩戴双耳可编程助听器，并在助听器与通气（2.2毫米平行通气孔）和不通气耳模耦合时选择他们偏好的插入增益。采用在安静环境中呈现话语段落的改良单纯形程序来确定偏好的插入增益。结果表明，通气提高了受试者在聆听和发声任务期间对助听器的质量评级，但没有改变受试者的单词识别分数。这些结果表明，应使用通气耳模来实现目标插入增益，以最大限度地提高患者对助听器的接受度。
