Patent ID: 8724836

Claim:
A hearing device with a housing, comprising: a first transducer, a second transducer, a first chamber, a first pipe with a first sound inlet penetrating said housing, a second chamber, a second pipe with a second sound inlet penetrating said housing, and a signal processor configured to process output signals from said transducers and to provide audible processed signals to a user of said hearing device, said first chamber and said first pipe being fluidly connected to form a first conduit leading from said first sound inlet to said first transducer, said second chamber and said second pipe being fluidly connected to form a second conduit leading from said second sound inlet to said second transducer, wherein said first conduit forms a first acoustic resonator with said first chamber acting primarily as an acoustic compliance and said first pipe acting primarily as an acoustic mass, wherein said second conduit forms a second acoustic resonator with said second chamber acting primarily as an acoustic compliance and said second pipe acting primarily as an acoustic mass, wherein lengths of said first and second conduits differ, wherein frequencies of resonance f 1 , f 2 of said first and second resonators are equal, wherein at least one of said conduits comprises a first pipe section and a second pipe section separated from each other, and wherein the first chamber fluidly connects the first pipe section and second pipe section of the first conduit if the at least one of said conduits comprises the first conduit, and the second chamber fluidly connects the first pipe section and second pipe section of the second conduit if the at least one of said conduits comprises the second conduit.
