By way of a phenomenon called diffraction. You can do this experiment
with water. Although not totally correct, it will give you a very
visual insight into the matter.

An experiment with water can give you also a concrete view that the
energy dissipated in the walls of the 'tube' is not sufficient to set
them in motion. (you will have to respect the proportions, e.g.
(inertia of the air column/inertia of clarinet tube)=(inertia of water
mass/inertia of walls holding the water).

Then how does the sound get out of the holes that are open?
