The Effect of the Embouchure on the Volume of the Whistle

Abstract

The embouchure is one of the most important components to playing human whistle. The purpose of this study is to clarify the influence of the embouchure in the whistle on the volume in order to ascertain the validity of the description of the whistle instruction book. When the cross-sectional area and the thickness of the opening of the lip plate of the human whistling are varied each, the air inflow amount per unit time and the pitch and volume of the generated sound were measured. Based on the relationship between the amount of air inflow per unit time and the volume of sound generated, part of whistle teaching method and the whistle instruction book described based on experience was supported by physical experiments.
