Effect of simulated hearing loss on speech sounds perception

This study examined the effect of simulated hearing loss on the Speech-Sounds Perception Test (SSPT) performance of a sample of 24 young volunteers with normal hearing sensitivity. Bilateral air conduction thresholds were obtained on all participants. The SSPT was recorded on tape by a professional radio announcer. The tape-recorded stimuli were filtered through a calibrated audiometer and spectrum shaper to simulate two high-frequency losses. Results show a significant effect of simulated high-frequency hearing loss on SSPT performance. Clinicians are advised to exercise caution in attributing poor SSPT performance of their patients with suspected hearing loss solely to a central auditory processing deficit.
