Abstract: Lateral wire anemometry (LWA) has been developed for recording of air vibration. Standard anemometry is founded upon the hot wire method, and wire temperature changes in the oscillating air velocity in the range 800-1000 °C, which is less suitable because of the proper heat emission from the wire. LWA deals only with the initial slope of the changing wire resistance, and subsequent Fourier analysis enables measurements of periodic air velocity. The probe has been developed for precise mapping of the air velocity field in the front of the membrane, and local power emission of the membrane may be evaluated in the region fitted to 0.15 cm2.

AB - Lateral wire anemometry (LWA) has been developed for recording of air vibration. Standard anemometry is founded upon the hot wire method, and wire temperature changes in the oscillating air velocity in the range 800-1000 °C, which is less suitable because of the proper heat emission from the wire. LWA deals only with the initial slope of the changing wire resistance, and subsequent Fourier analysis enables measurements of periodic air velocity. The probe has been developed for precise mapping of the air velocity field in the front of the membrane, and local power emission of the membrane may be evaluated in the region fitted to 0.15 cm2.
