Abstract
Recently, some professional whistlers have set up music schools that teach musical whistling. Similar to singing, in musical whistling, the whistling sound should not be break, even when the whistling goes on for more than 3 min. For this, it is advisable to practice whistling the “Pii” sound, which involves whistling the “Pii” sound continuously 100 times with the same pitch. However, when practicing alone, a whistler finds it difficult to count his/her own whistling sounds.<br>In this paper, we propose a whistling sound counter based on piezoelectric bone conduction. This system consists of five parts. The gain of the amplifier section of this counter is variable, and the center frequency (f0) of the BPF part is also variable. In this study, we developed a prototype of the system and tested it. For this, we simultaneously counted the whistling sounds of nine people using the proposed system. The proposed system showed a good performance in a noisy environment.<br>We also propose an examination system for awarding grades in musical whistling, which enforces the license examination in musical whistling on the personal computer. The proposed system can be used to administer the 5th grade exam for musical whistling.
