Several different specially designed flowmeters, both in the sonic frequency region, f = 3.1 kHz, and the ultrasonic frequency region, f = 40 kHz, for measuring air velocities were investigated. Special emphasis was given to measurements of very low air velocities, i.e. lower than 1 m s-1. The flowm
In the recent years a considerable amount of mathematical work has been devoted to the study of reflected signals obtained by the propagation of pulses in randomly layered media. We refer to [M. Asch, W. Kohler, G. Papanicolaou, M. Postel and B. White, "Frequency content of randomly scattered signal
