Abstract
An acoustic waveguide includes a body defining a resonance chamber. The body has a tubular section defining a cylindrical central portion of the chamber along a longitudinal axis. First and second end sections extend from opposite ends of the tubular section. Each end section includes an end wall tapering away from the tubular section and towards the longitudinal axis, thus defining a conoidal end portion of the chamber.
