If sound is perceived as annoying or even painful, it becomes noise. We are often exposed to noise daily, to environmental noise. This type of noise 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 in more complex ways like through reflections, diffraction, conversion of structure-borne sound to air-borne sound.
In case of a complaint, on one hand, the operator of an industrial plant can use the Acoustic Camera to find out where measures could be taken. On the other hand, an operator can use the sound localization system to prove that this noise is not coming from his facility, but someone else is causing the problem.
A recycling company has already implemented noise-reducing measures by building a very long and 15 m high noise barrier. Nevertheless, some residents are affected by the noise during the day. By measurements with the Acoustic Camera, a rock wall could be detected which reflects the loud emissions over the noise barrier.
In another case, there is a complaint that an industrial plant is too noisy and the authorities confirm this condition. The entire system consists of dozens of fans, coolers, compressors, other openings, truck delivery traffic and internal forklift truck traffic, etc. Where should an improvement take place? What and where are the acoustic hotspots? A few measurements with the Acoustic Camera lead to clear statements as to where suitable measures can be taken most effectively.
