- Many sounds are produced by coupling the mechanical vibrations of a
source to the resonance of an acoustic tube:
- In vocal systems, air pressure from the lungs controls the
oscillation of a membrane (or vocal fold), creating a variable
constriction through which air flows.
- Similarly, blowing into the mouthpiece of a clarinet will cause the
reed to vibrate, narrowing and widening the airflow aperture to the
bore.
- Sound sources of this kind are referred to as
pressure-controlled valves and they have been simulated in various
ways to create musical synthesis models of woodwind and brass
instruments as well as animal vocal systems.
