| Outline of Final Research Achievements |
In this study, We constructed a detection system of direct bone conducted sound using a titanium implant of bone anchored hearing aid with skin penetration and clarified the following things; 1) In non-noisy condition, the high frequencies sound power in the direct bone conducted sound did not decrease. Therefore, those vowels distortion also decreased. However, in auditory psychological examination, there were no significant differences for the clarity and the easy listening of monosyllables between the direct and the non-direct bone conducted sound. 2) In comparison with air conducted sound, the clarity of the direct bone conducted sound for monosyllables and words task showed significant differences in noisy condition, especially strong noisy condition (95dB).
