The "hissing" tone holes are NOT because there is air flowing out of them. It is because the pressure waves are being compressed by the tone hole, or their impedance is being interrupted by a pad that does not allow enough clearance (we refer to "end effect", and everybody understands that where the bell in concerned- but this same principle applies to tone holes and here "end effect" is being hampered by lack of pad clearance).
Yes it IS true that there is SOME "air-flow" in a clarinet, but by the time you reach an open tone it is very diffuse. By the time you are halfway down the top joint the airflow is so diffuse it is almost immeasurable.
I know no one believes anything I ever say on this stupid format, but just go ask a physicist. Having actually being involved in attempts to scientifically measure airflow I can tell you unequivocally that I am right. Sorry mate.
