Abstract
A binaural hearing aid includes: at least one signal processor; a first microphone system for provision of a first input signal; and a second microphone system for provision of a second input signal, where the first microphone system is adapted to be placed in or at a first ear of a user, and the second microphone system is adapted to be placed in or at a second ear of the user. The signal processor is configured for: obtaining modulations of the first input signal and the second input signal with at least the first microphone system being in an omni directional microphone mode; evaluating the modulations of the first input signal and the second input signal; and setting one or both of the first microphone system and the second microphone system based on a result from the act of evaluating.
