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.

The Search for the Cause

recycling company has already implemented noise-reducing measures. A very long and 15 m high noise barrier. Nevertheless, some residents are affected by the noise during the day. By measuring with the Acoustic Camera, a rock wall can 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 routes of forklifts, etc. Where should an improvement take place? What and where are the acoustic hot spots? A few measurements with the Acoustic Camera lead to clear statements as to where suitable measures can be taken most effectively.

  • Acoustic eraser
  • Up to long measurement distances
