Paper Abstract

Measurements of acoustic pressure oscillations on curvilinear surface streamlined by a flow, for example, on the wall of wind-tunnel or airfoil is necessary to supply for aeroacoustic appendices. Microphone should have the minimal sizes and feeler set flush-mounted. Such microphones are demanded for creation distributed audio-systems and noise reduction devices in the source. Developed the MEMS-microphone with corrugated diaphragm should have a sharp response, stability to effects of ram airflow and high level pressure. Preliminary simulation of design and technological parameters is necessary for creation of this microphone.
