Why do you use a whistle with a pea for deaf games.. or is that some inside joke I am missing (:

Fox 40s are pealess but are very loud -- however because of its design there is no detectable vibration. Although it's faint, a vibration emits from a pea whistle, which deaf kids are much more likely to pick up.
I am just speculating though, correct me if I'm wrong. |
I would agree, makes sense.

I worked a deaf school back in the early '90s and used a Fox. I haven't owned a pea whistle since my first year and haven't used one since my second assignment. We didn't have any problems in our game with our Fox's.

On the other hand, I've often wondered if the Fox's three-chamber design was an attempt to imitate the sound of the pea whistle by using three dissonant frequencies. |
Drizzle, you are spot on, cheers

Fletcher and Munson found that - differently for different frequencies - lower pitched sounds had to be a lot more energetic to create the same perceived loudness as higher pitched ones. This would seem to argue against the pea-whistle getting through better to deaf players. What is the actual experience of near deaf players??? |
The pea whistles have a lower tone register and not as many high pitched over tones as the fox, that's why I use the pea, I've got an ear injury that "allows" me to hear over tones that most people can't pick up, and you should be glad, it sounds like h*ll :(

The fox 40 has a very high pitch. The pea would created vibrations closer to the most sensitive human hearing range. For partially deaf people, the loss is often at the frequency extremes (it's probably different in each individual)...so bringing the whistle frequency more to the middle could help. I have a coworker who is essentially completely deaf. However, there are a few very low frequency sounds that she can hear...if they're loud. [Edited by Camron Rust on Jan 28th, 2006 at 04:08 AM] |
