Hi,
for point 2 ... I don't really think that a dog could hear the pin hit the floor from 20 meters far in a concert... not that have importance here...
but I think in a concert there's enough ultrasound noise to swamp any tiny amount due to the pin.
Even if a person rubs his eyes or the crown jewels area... there will be alot of ultrasounds generated...
now... think at a boring , tedious concert with violins (this also generates plenty of ultrasound waves), basses and oboe stuff... I think many boys that are there just to partner their girl... who is possibly passionate of classical music... instead of being at home...on the sofa... playing with their playstation3...
drinking beer and screaming blasphemies ... will rub eyes/jewels... thinking "how much it takes that damn $@!& concert... wanna go home...drink the beer...etc"
Now... the problem is: is the dog able to discriminate ultrasound generated by the pin hitting the floor and all the rubs there ???
I don't think so.
Kind regards,
Max
