3D acoustic map measured in situ at an industrial plant
Real three-dimensional cartography of over 6,000 m² to prioritise Occupational Risk Prevention measures.
The challenge
In a highly complex industrial plant, with over 6,000 m² of production area and multiple simultaneous processes, precisely identifying where the acoustic problem originates and how it propagates within the enclosure is key to effective action.
Unlike approaches based on modelling or estimates, the need was for real measured data that would allow reconstruction of noise behaviour across the volume of the space, identifying accumulation zones, preferential propagation directions and high-exposure areas with far greater precision than conventional point-based campaigns.
The solution
SNA applied state-of-the-art technology to perform a real three-dimensional measurement of the interior acoustic field, obtaining a 3D cartography of noise propagation.
The system's differential value is that it provides not only overall levels but also spatial and spectral information, enabling exact location and quantification of dominant sources and the frequencies that most impact the immediate environment. This is especially relevant for Occupational Risk Prevention, as exposure depends not only on the total level but on the frequency content, persistence and actual distribution of noise at workstations.
The result
The result was an objective, highly visual diagnostic tool: a "measured 3D acoustic map" that enables prioritising corrective measures with technical criteria, optimising investments and designing more effective ORP actions (zoning, source control, screening, encapsulation, exposure protocols and PPE selection), based on real data rather than hypotheses. An evolution towards industrial acoustics based on advanced measurement, where technology provides precision, decision speed and maximum preventive value.
