Couldn't hear the high pitch
0 of 1 found this helpful Because of high register hearing loss I can't hear the beeps very well. If only it were a lower frequency beep (like around 500 hz). I can hear the beeps when it is in my swim cap, but as soon as I am splashing in the water, I can't hear the beeps any more. I couldn't hear the beeps running outdoors either. I suspect for someone with better ears, it is fine. I don't know, but I would guess it is about 3000 hz.
