Hi Don, With 55 dB of boost at 3500 Hz, a throat mic does pick up the "s" sound. You can even distinguish S from SH. In fact, don't whistle, because the other people will complain.
There is a definite GNYENG-GNYENG quality to the speech, but it is quite intelligible. It can sound really funny when a deep-water diver is breathing a helium mix. HA!!! With so much gain and EQ, it gets noisy, especially with six live throat mics on a system. I deliberately screwed up the low end tracking of a 2:1 analog compansion system to make it act like a gentle noise gate, and it really helped this. Each mic had a 2:1 on its radio link, and the return bus also had 2:1. A little skew, and the noise became tolerable, not an issue. That was one of my last mods before I left that company. Oh man, you also have to be careful to have the throat mic muted while you put the thing on. Otherwise, the scratching noises will blow out everybody's ears. 55 dB of boost... Yeowch! A good system should have peak limiting with some top end boost in the level detector. There are also ear mics on the market. They don't sound so good, and they pick up lots of extraneous noise. That's not good, because usually you want a non-air mic to block out noise, although sometimes it's to allow underwater speech while using SCUBA gear. I think for most purposes, a throat mic is the way to go if you can't use an air mic.
