- Title
Calculation of Infrasonic Noise Characteristics by Measuring the Current Values of a Two-Dimensional Wind Wave Field.

- Abstract
The paper presents a scheme for calculating the current sound pressure values excited by wind waves in the infrasonic frequency range (0.1–5 Hz). The calculation is based on measuring the time dependence (variability) of the two-dimensional profile of the excited surface on the plane XY with characteristic dimensions exceeding several surface wave lengths. The paper provides a scheme for processing a dataset which measures the level of standing wind waves and then directly calculates the time dependence and the wave-generated acoustic noise spectrum. The authors present the results of calculating the averaged infrasonic noise spectrum and the spatiotemporal wave spectrum for the specific water area where the wave characteristics were measured.
