We have been studying a dual microphone system that achieves both noise resistance and high sound quality by combining a bone conduction microphone and an air conduction microphone so that it is easy to make a call even in a noisy environment using a communication terminal such as a mobile phone. In this report, we are investigating how changing the mixing ratio of bone conduction voice and air conduction voice affects the audibility of synthetic sounds. From the test results of single syllable articulation score, it became clear that the relationships between different under silent, 70 dBA and 90 dBA noisy environments. It was also found that even under noisy conditions, the single syllable articulation scores were not significantly affected within a certain mixing ratio range. |
