For awhile in Va Beach I worked at Target (I'm sure most of you remember. I was all about the full drama run downs every day). I was very often there in the backroom (warehouse) when they had a vendor delivery during the day. Chips, sodas, etc. are often stocked by vendors who buy the space, not by the actual store employees. So these guys would bring in their supplies in the morning through the warehouse, with their huge trucks idling in the dock while they off loaded. I discovered that the particular frequency of sound created make me nauseous.
I don't know how common that is though. I don't think I've ever seen anyone feel off or odd because of a noise (unless it was loud or high pitched).
And there's always this neat little way of determining how deaf you are. I stop hearing it after the 16000 Hz range. Guess that's not too bad. But it does mean I have some high end hearing loss. Which uh ... isn't really shocking given how many amp stacks I've leaned against. Apparently I was supposed to be wearing ear plugs.
