Abstract
A whistle is a type of tool that produces sound by blowing among various signaling tools. The whistle has evolved structurally to produce sharp and strong sounds, and due to its characteristics, it is effectively used in fields where clear intentions are expressed. The main fields where whistles are used are as referees in sports games, when the police control the surroundings, and when individuals are notified of danger. In addition, whistles used in each field are classified into unique whistles with individual characteristics according to their purpose. This paper is a study to verify whether representative whistles used according to their purpose in the three fields presented above are effectively utilizing the sound characteristics appropriate for the situation. For the study, the sounds of the three representative whistles were compared and analyzed. As a research method, the sound characteristics of the three whistles were scientifically analyzed, and the listeners' responses were investigated and compared. As a result, a referee whistle in sports games, a police whistle, and a self-defense whistle showed strong sound signals and unique tones in that order. In addition, the sounds of the three whistles have been learned through experience by the general public, so they can be easily distinguished by field and verified to be used appropriately for the situation.
