Abstract

Although Microflown particle velocity sensors have been around for several years they have never been tested thoroughly for space related vibro-acoustic applications. Within the framework of the ESA funded MEVAT project, Microflown Technologies has been investigating the feasibility of using PU sensors in high sound level environments in cooperation with ESA and IABG. The full sound vector can be measured with PU probes, which consist of acoustic particle velocity sensors and a conventional microphone. Applications of such probes range from the vibration, total acoustic energy, sound source radiation, acoustic impedance and/or diffusion measurements. For this project special one-dimensional and three-dimensional PU probes have been developed, as well as the required mountings and calibration methods. A large array has been constructed and their functionality has been tested. Test results from this project will be presented.
