its limitations for this application.
Define inertance in an acoustic system and describe the relationship between
inertance and mass. Discuss briefly why inertance is often used instead of mass
to describe an acoustic system.
Calculate the total volume of a Helmholtz resonator that has a neck length of
2.8 cm, a neck radius of 1.2 cm and a Quality factor for the system, Q = 148.
Assume the open end of the neck is unflanged.
Calculate the maximum power output of the Helmholtz resonator described in
(c) when the mass of air in the neck is stimulated by a sound wave with a
pressure amplitude of 2 Pa.
