Abstract

The disclosure relates to a hearing device configured to be at least partially inserted into an ear canal, the hearing device comprising an acoustic transducer (151, 351) having a membrane (153) configured to generate sound waves; a housing (111, 311, 411, 511) enclosing a first chamber (105) and a second chamber (106) acoustically coupled by the membrane (153); a sound outlet (131) configured to release sound waves from the first chamber (105) into the ear canal; and an acoustic port (135, 335, 615) acoustically coupling the second chamber (106) to an ambient environment outside the ear canal.A customization of the frequency response can be achieved by a resonant member (140, 240, 340, 440, 540) configured to resonate with sound waves at a resonance frequency, wherein the second chamber (106) is acoustically coupled to the resonant member (140, 240, 340, 440, 540, 640).
