要約(英語): Whistling competitions have been held regularly in Japan in recent years, and some prize-winning whistlers have established music classrooms to teach musical whistling. The principle of sound production in human whistling is not well-known. A good understanding of the principle would be very beneficial to both the trainer and the trainee. The purpose of this study is to clarify the influence of the non-circularity of lip opening in the whistle on the volume in order to ascertain the validity of the description of the whistle instruction book. When the ellipticity of the opening of the lip plate of the human whistling model is varied, the pitch frequency and volume of the generated sound are measured. Based on the relationship between the ellipticity and the volume of sound generated, the whistle instruction book described based on experience was supported by physical experiments.
