Approaches for Obtaining and Processing Snow Avalanche Acoustics Emission Data

Sergejs Bratarčuks, Aleksejs Sazonovs

Work overviews methods of acoustic signal acquisition and digital signal processing, applying them to task of geography and danger management. Previous researches indicate that snow slopes produce acoustic emission signals before the avalanche slides down. Sensors, preamplifier and recording-interface combinations are being tested for ability to record low-frequency acoustic impulses.
