I can attest to this as well.  After experiencing ringing ears once I 
now wear those big shooting ear protectors when doing a lot of work 
with my larger coil.  One interesting thing I've noticed is that dogs 
all over the area start barking when I run the coil.  It's a little 
strange since the barn is in the woods, a good quarter-plus mile away 
from the nearest dog, and they don't seem to mind other sounds such 
as circular saws, chain saws, etc.  No doubt there is a very strong 
ultrasonic component to a Tesla coil streamer, but I wouldn't expect 
that to travel very far at all.  Perhaps it's just because the coil 
sounds a little "different" than other devices.   It sure gets them 
all barking though!
