BINAURAL HEARING AID SYSTEM

摘要

A binaural hearing aid system (45), comprising a left ITE hearing aid (42) with an antenna facility (28), a right ITE hearing aid (13) with an antenna facility (28), means for transmitting audio signals between the antenna facility (28) of the left ITE hearing aid (42) and the antenna facility (28) of the right ITE hearing aid (43) and means (60) for a binaural beamforming based on the natural directivity of the pinna and/or based on a head shadowing effect, wherein the antenna facility (28) of each of the ITE hearing aids (42, 43) comprises an antenna arrangement (16, 36) with a coil core (22, 32) made of magnetically permeable material, and extending along a longitudinal axis (27), a further electric hearing aid component (14, 34), which emits electromagnetic interference radiation, and an at least partially planar shield (26, 37) made of magnetically permeable material, wherein the shield (26, 37) is arranged between the antenna arrangement (16, 36) and the further hearing aid component (14, 34), wherein the shield (26, 37) is arranged transverse to the longitudinal axis (27) of the coil core (22, 32) and wherein the shield (26, 37) is arranged at a distance of 50 to 150 micrometers from the coil core (22, 32), preferably 75 to 100 micrometers.
