I am just speculating though, correct me if I'm wrong.
I would think that pea-whistles make more 'noise' in the process of creating sound - the pea whacking up against its confining chamber; and such noise probably has low frequency components that the Fox 40 lacks. Are deafnesses equal across frequencies?

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???
