Stimulating the auditory nerves with an infrared laser may produce hearing without the surgery. The purpose of this study was to establish the speech encoding scheme for an auditory prosthesis with an infrared laser, and evaluate its efficacy for age-related hearing loss (AHL). We synthesized Click-modulated sound (CMS) as simulation sounds for the laser auditory prosthesis, and age-related hearing loss simulation sounds (AHLsim). Six native Japanese speakers with normal hearing participated in the experiment, and AHLsim, CMS, or AHLsim and CMS simultaneously (AHLsim+CMS) were presented. They reported their perceptions of each stimulus. As a result, the correct answer rate of AHLsim+CMS was significantly higher than that of AHLsim, especially for consonants in the high frequency area (i.e. K, S, H). Our data suggest that irradiating the high-frequency region with an infrared laser may support speech recognition of elderly people., application/pdf},
