If sound is perceived as annoying or even painful, it becomes noise. We are often exposed to noise on a daily basis as environmental noise. This type of noise source can have different origins. A distinction is made between industrial, construction, transport, leisure and neighborhood noise. This noise can reach our ears either directly or on more complex paths (reflections, diffraction, conversion of structure-borne sound to air-borne sound).
In the event of a complaint, the operator of an industrial plant can use the Acoustic Camera to find out where measures can be applied. Otherwise, an operator can use the sound localization system to prove that noise is not coming from his facility, but someone else is causing the problem.
