Abstract
A hearing aid includes a microphone, an electro-acoustic transducer, and a housing that supports the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume. The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the front acoustic volume and such that a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. The hearing aid is configured such that the first and second acoustic volumes are acoustically coupled to the microphone when the hearing aid is worn. The housing supports an acoustic element that is acoustically coupled to the microphone and the second acoustic volume and is arranged such that acoustic energy radiated from the acoustic element sums with acoustic energy leaked from the first acoustic volume at the microphone so as to cancel each other.
