Abstract (en)
[origin: EP2757810A2] The arrangement (1) has an electronic control device provided with an evaluation unit connected to two micro-electro-mechanical-system (MEMS) microphone capsules (4, 5). Directional characteristic of the arrangement is more adjustable by a control unit. A sound chamber is arranged between the wind protection devices, so that characteristic of wind direction and intensity of wind signal is calculated by using the MEMS microphone capsules, and directional characteristic of the arrangement is adjustable by using the control unit based on wind signal characteristic.
