Hearing disability and hearing aid benefit related to type of hearing impairment.
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.
