Factories with acoustic non-compliance: precise identification of critical sources
Selective diagnosis that identified the truly responsible sources and drastically reduced corrective investment.
The challenge
In the industrial sphere, one of the main acoustic challenges is the coexistence of multiple noise sources operating simultaneously, located at different heights, in different enclosures and with very varied typologies. This complexity greatly hinders the precise identification of the sources responsible for regulatory non-compliance externally.
SNA intervened at an industrial plant that showed significant impacts on sound levels measured in the surrounding environment, exceeding the limits established by applicable regulations. The difficulty lay not only in the overall emitted level but in the combined interaction of equipment, structures, indirect transmissions and complex propagation phenomena.
The solution
Within the Advanced Industrial Acoustics line, a specific methodology was developed that precisely identified the position and individual contribution of each problematic point towards the exterior. Through spatial analysis techniques, high-resolution directional measurements and detailed acoustic modelling, it was possible to discriminate which sources were truly decisive in regulatory non-compliance.
The result
This approach substantially optimised the corrective measures. Instead of applying generalised and economically oversized solutions, action was taken exclusively on critical sources, reducing the necessary investment and maximising the technical effectiveness of the interventions. Engineering shifted from reactive to strategic: precise diagnosis, quantified analysis and selective solution design where methodological innovation, technical control and economic optimisation converge to transform a complex problem into an efficient, sustainable intervention.
