Outline of Final Research Achievements

This research is examining three points: (1) technology to protect of auditory function, (2) technology to improve of auditory function, and (3) technology to improve speech intelligibility. Firstly, in technology (1), it was found that subjects can percept in the range of approximately 12 dB to 13 dB when gradually attenuating the volume. Next, in technology (2), it was found that the speech recognition ability was improved by training to repeatedly sound of various frequencies and levels. Finally, in technology (3), it was found that speech intelligibility is improved by processing to shift the formant frequency of a person with low intelligibility to the formant frequency of a person with high intelligibility.
