Environmental Noise

Noise is a consequence of human activity therefor it can't be removed from our daily routine but it should be assessed to the cause, controlled and sometimes suppressed or lowered to allow a sufficient quality of live in the surroundings.

Several noise sources and applications are typically included in the so called environmental noise control:


AVS Aircraft Monitoring	Far Field Scan & Paint	Motorbike on the road pass-by test

AVS community noise surveillance	Portable AVS Noise Mapping	Time domain noise source localization

Microflown’ s AVS monitoring system is based on the USP probe, formed by 3 particle velocity sensors and one pressure microphone. The setup allows to calculate the direction of arrival of the noise in a very wide frequency range, 0 to 20.000 Hz. Combined with other tools such as Transfer path analysis calculation or simulation, event detection, camera surveillance, noise source classification… permits to fulfill the requirements and needs of the Environmental Noise Control.
