Abstract
A new test battery has been designed with the intention of assessing the effectiveness of hearing aids for the perception of music. Within each subtest discrimination thresholds for low-level acoustic dimensions are determined adaptively using a 2AFC method within the context of a musical judgment regarding melody, harmony, timbre or meter. The presented test stimuli are synthesized and either unprocessed or processed by different hearing aid signal processing algorithms before being played back via loudspeaker. The battery will be used to evaluate different hearing aid algorithms with regard to their benefit for functional hearing in music. A group of eight normal hearing (NH) control participants and eight hearing impaired participants each performed the timbre and meter subtests of the battery twice. Significant differences in the performance could be found.
