Abstract
A whistle is structured for promoting hygienic use of the whistle and for maximizing inlet air pressure to generate sound from the whistle. The whistle includes an air inlet having a channelizer for dividing and channeling air flow received from the air inlet through at least two different channels. A sound-generating chamber is in corresponding fluid communication with each of the channels, and an air exhaust is in fluid communication with the sound-generating chamber. The air exhaust is structured and located on the whistle body for generating a sound, and is positioned and structured at a location suitable for directing air flow away from the air exhaust in a generally downwardly and/or opposing direction with respect to a generally horizontal air flow direction at the air inlet.
