ACOUSTIC MEASUREMENTS OF WIND THROUGH A LAYER,

Abstract

A simple acoustic device for improved measurements of the mean horizontal air flow through an atmospheric layer between the surface and an elevation of 200 feet is described. It consists of a sound generator and four microphones arranged in the shape of a symmetrical tetrahedron. The wind in this layer is acoustically weighted and integrated along the path length from the surface, where the microphones are located, to the top of the layer, where the sound generator is placed. Results obtained with this acoustic device compare favorably with the data collected from conventional wind sensors. (Author)
