Sound is produced by generating pressure waves that travel through the air
and are perceved  by the ear. The faster the waves the higher the pitch, The
more the air is compressed the louder the sound. A spark heats the air and
causes a presure wave. The TC spark is powered by a capacitor discharge with
a lot of current/heat to generate high pressure waves. The more waves you
make the more it hits your ear.
