[AT] Noise Concerns

[Ken Knierim]

My concern is with hydrostatic drives (like Bobcats use) making noises
above normal hearing range... it sounds quiet(er) but you're still half
deafened. Perhaps it's not as bad as I think but I'd like to know more. I
usually have my shooting protectors on (habit) but I don't know the ins and
outs of the noises it generates... and possible ultrasonic damage to my
ears.
