Context is important, what are you going to use your whistle for? Outdoor safety, marine sports, refereeing football – all require a different whistle to sound loud and clear in highly specific circumstances.
Most important of all is choosing the right whistle for you. A young child, an asthmatic person and a hockey referee will all need to make different personal choices – as will many others.
In a survival situation your choice could be the vital difference between being found and being lost!
Trying to educate people about whistles is not an easy job. Often dog handlers who see the way dogs respond differently to different whistles understand the performance factors best of all.
The whistle design is critical to good performance. Good design controls the three major factors which you must consider when choosing the right whistle for you.
- How hard or easy is it to blow? (Blowrate)
- How loud is it? (Blowsound)
- What sound or frequency does it have? (Blowtone)
