Influence of stratification of wind velocity and atmosphere bottom layer temperature on propagation of low-frequency sound waves

Subject of investigation: field of the wave of a low-frequency sound and an acoustic pulse. Purpose of the work: influence of the stratification of the atmosphere bottom layer and underlying ground surface on the field of the wave of the low-frequency sound and acoustic pulse. The work provides an experimental confirmation of the wave theory. New results are obtained on the attenuation of the low-frequency waves for various types of the stratification of the atmosphere bottom layer. Studied are the laws of distortion of the shape and duration of the pulse depending on the direction of propagation, distance to the source and stratification of the atmosphere boundary layer. The results were used in the scheduled work of the Institute of the Atmosphere Physics. Field of application: prediction of propagation of a low-frequency sound under different meteorological conditions and power estimation and location of the sourceAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
