Abstract (en)
[origin: EP2169984A2] The device (1) has directional microphones (M1-M3) picking up an acoustic input signal and creating electrical microphone signals (S1-S3). A signal processing unit (2) processes and amplifies the electrical microphone signal, and creates an electrical output signal. An earpiece (3) converts the electrical output signal into an acoustic output signal. The directional microphones provide directional effect based on the amplification of the electrical microphone signal, where the directional effect comprises a first-order directional effect set below a threshold value of the amplification. An independent claim is also included for a method for operating a hearing aid device.
