It is subjective to believe that a person decides, not by the blowing but
by the feeling! The tester certainly does not know if the person can
distinguish between them! A lot of talk about scientific process
.....when the bottom line is, using the hands on a horn does in fact
affect resistance of the air pressure. I certiainly would want to use my
own fingers over the horn than rely on someone else's ....or a machine for
that matter!
