Abstract: Page 9 A coupler for an acoustic device includes a main opening for inserting the acoustic device or an adapter for the acoustic device. The coupler also includes a main channel connected at one end to the main opening. The coupler further includes one or more leakage paths for allowing sound to escape the main channel when in use. The coupler additionally includes one or more acoustic resonators connected to the main channel. The one or more acoustic resonators includes a first acoustic resonator configured to have a fundamental resonance frequency in the range of 500 Hz to 1 kHz and a second acoustic resonator configured to have a fundamental resonance frequency in the range of 3.85 kHz to 5 kHz.
