One of the important properties required in sport whistles is production of a more accessible sound in noisy surroundings. Many whistles with various structures have been developed, and the evaluation method of their performances has been based on the conventional sound parameters, sound pressure and tone obtained from frequency analyses. However the relationships between sound parameters and subjective assessment results have not been clarified. Four kinds of whistles were used in this study. Sensual testing results and their sound properties are compared. The limitation of the conventional frequency analyses is discussed by comparison. A new parameter, WSP (Whistle Sound parameter) in which both pressure fluctuation and pressure modulated Frequency was incorporated, was proposed. Then, the validity of WSP is discussed. It was confirmed that WSP was an effective parameter for the evaluation of whistle sound.
