This study was designed to investigate whether patients with a conductive hearing impairment derive more benefit from the provision of a hearing aid than comparable individuals with a sensorineural hearing impairment. A secondary aim was to assess the relative hearing disability of those with each type of impairment. Twenty-eight patients with a bilateral, symmetrical conductive impairment were selected. They were matched for age, sex and speech frequency average to individuals with a bilateral, symmetrical sensorineural hearing impairment. Each patient performed free-field audio and audio-visual tests in noise, both with and without a hearing aid, during which the non-test ear was acoustically occluded. When unaided, individuals with a conductive impairment were more disabled than those with a sensorineural impairment. On the other hand, those with a conductive impairment derived more benefit from an aid than those with a sensorineural impairment.
本研究旨在调查传导性听力障碍患者相较于具有感音神经性听力障碍的类似个体，佩戴助听器是否能获得更多益处。次要目的是评估每种类型听力障碍患者的相对听力残疾程度。选取了28例双侧对称性传导性听力障碍患者。将他们按照年龄、性别和言语频率平均值与双侧对称性感音神经性听力障碍患者进行匹配。每位患者在有和没有助听器的情况下，均在噪声环境中进行自由声场音频和视听测试，测试期间非测试耳进行声学封闭。在未佩戴助听器时，传导性听力障碍患者比感音神经性听力障碍患者的听力残疾程度更高。另一方面，传导性听力障碍患者佩戴助听器后比感音神经性听力障碍患者获益更多。
