Abstract: 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.

Abstract: A system, a method and an autonomous network for vibration monitoring, the system comprising a master station preset for recording vibrations at a master trigger threshold; a secondary station, the secondary station and the master station being time synchronized, a server in communication with the master and secondary stations; wherein, the master station is configured to transmit a master trig time to the server and to start recording vibrations when the master trigger threshold is exceeded; the server is configured to store the master trig time; the secondary station is configured to detect the master trig time stored by the server, and upon detecting the master trig time, to record vibrations; and wherein the master and secondary stations are configured to transmit respective recorded vibrations to the server and the server is configured to classify the recorded vibrations in relation to a preset seismic threshold.
