要約(英語): Recently, some professional whistlers have set up music schools to teach musical whistling. However, so far, there is no licensed examination for musical whistling. In this paper, we propose an examination system for evaluating musical whistling. The system conducts an examination in musical whistling on a personal computer (PC). It can be used to award four grades, from the second to the fifth. These grades are designed according to the standards adopted by the school for musical whistling established by the Japanese professional whistler Moku-San. It is expected that the group examination of this examination is held in the examination center where other general certification examinations are held. Thus, the influence of the whistle sound on the PC microphone normally used should be considered. For this purpose, we examined the feasibility of using a bone-conductive microphone for a musical whistling certificate examination system. This paper shows that the proposed system in which bone-transmitted sounds are considered gives good performance under a noisy environment, as demonstrated in a group examination of musical whistling using bone-transmitted sounds. The timing of a candidates whistling tends to not match because the applause sound output from the PC was inaudible for a person older than 60 years.
