AE signal arrivals to receivers are governed by the subsurface variability, Snell's law, and AE wave propagation direction. These factors should be considered...

... and Snell's law. AE measurements show 1) similar signal travel time to sensors located across the void when the void in the concrete blocks was empty and when filled with various backfill types; 2) increasing backfill age had no influence on the signal travel time to the sensors. It was also found...
