Sounds just like a normal whistle! Squeeze it rather than blow into it for an easy to use whistle. The squistle has been developed by PE teachers to reduce the risk of transferring germs from one user to the next. This hand operated whistle’s size will reduce the risk of it getting lost. As well as operating as a whistle, this tool is a great product for occupational therapy. It demonstrates cause and effect and needs to be squeezed to produce a sound. It can therefore be used as a hand exerciser to promote muscle use.
Whistle sound is 80-85dB
