Abstract (en)
The disclosure relates to a hearing device comprising a housing (111) configured to be at least partially inserted into an ear canal and enclosing an inner volume (116) separated into a first volume portion (117, 118) and a second volume portion (117, 118) by a partition including an acoustic transducer (151, 251), wherein a sound outlet (122) and an acoustic port (135, 435, 615, 635, 735, 835, 911, 927, 949, 959, 970) is provided at the housing (111).To allow modification of acoustic properties inside the inner volume (116), the disclosure proposes a first resistive member (131, 171, 221, 371, 471, 571, 671, 771, 871, 901, 905, 926, 948, 955, 975) and a second resistive member (131, 171, 221, 371, 471, 571, 671, 771, 871, 901, 905, 926, 948, 955, 975), each configured to attenuate sound waves between a first terminal and a second terminal, wherein the first terminal of the first resistive member is acoustically connected to the acoustic transducer (151, 251) via the first volume portion (117, 118), and the first terminal of the second resistive member is acoustically connected to the acoustic transducer (151, 251) via the second volume portion (117, 118), and wherein the partition (115, 175, 215) includes the first resistive member placed in parallel to the acoustic transducer (151, 251).
