Abstract

See full text

A method and a system for noise discrimination, the method comprising measuring noise levels of a noise source, measuring noise levels at a target location positioned at a distance from the noise source, measuring wind speed and direction in an area comprising the noise source and the target location, filtering transient short-duration events from the noise levels measured at the noise source, yielding filtered noise levels of the noise source, filtering transient short-duration events from the noise levels measured at the target location, yielding filtered noise levels of the target location, measuring a sound transfer function between the noise source and the target location using the filtered noise levels, comparing the measured sound transfer function with a reference transfer function; and when the difference between the measured transfer function and the reference transfer function is above a predetermined threshold, determining a probability that noise at the location originates from the noise source.
