Abstract

Properties of the air such as temperature, pressure, humidity and air flow can modify the propagation pathway of an acoustic signal. By making acoustic measurements of a known acoustic path it is possible to estimate at least one of the temperature, the pressure, the humidity and the air flow using perturbations present in the measured signal. Moreover, by combining data from several acoustic pathways topographical reconstruction of profiles of at least one of the temperature, the pressure, the humidity and air flow can be obtained. Profiling these data over an extended volume such as an office or green house is particularly important for local control.
