Abstract
An acoustical module including a receiver unit for generating audio sound, microphone units for receiving acoustical pressure signals, and acoustical pressure pick-up points. Each of the acoustical pressure pick-up points is acoustically connected to a microphone unit. The module further includes an acoustical filter for attenuating acoustical pressure signals from a first acoustical pressure pick-up point relative to a second acoustical pressure pick-up point. The invention further relates to a hearing device comprising an acoustical module.
