Environmental Noise
Measurement and evaluation of noise
Environmental noise refers to sound generated by mobile sources, such as traffic, and fixed sources, such as industrial activities or installations, which affects both the population and the environment in different contexts.
Why environmental noise measurements matter
Environmental noise measurements are used to assess noise exposure, conduct acoustic studies, and verify compliance with regulatory limits.
What is evaluated in environmental noise?
Environmental noise measurements address how noise:
-
Propagates from sound sources
-
Varies over time depending on activity and environmental conditions
-
Affects the population in terms of noise exposure
The objective is to quantify noise levels and evaluate their compliance with limits and criteria established by regulations, both through spot measurements and continuous monitoring.
Measurement accuracy and standard compliance
Reliable environmental noise measurements require Class 1 instrumentation compliant with IEC 61672. Frequency analysis must comply with IEC 61260.
Environmental noise assessment is carried out in accordance with international and local regulations and directives, such as the Environmental Noise Directive (END), the ISO 1996 series for the description and assessment of environmental noise, and applicable national standards.

Noise source evaluation
Determination of sound levels generated by specific sources, such as traffic, activities, or installations, to characterize their acoustic behavior at the source. This allows analysis of the acoustic performance of the source and its potential impact on the environment. Read more...

Noise levels at specific locations
Determination of sound levels at reception points using indicators such as equivalent levels, maximum levels, or percentiles such as L90, to characterize the acoustic conditions. These values represent the actual noise conditions at a specific area or location. Read more...
Noise exposure assessment
Determination of noise exposure using indicators such as Lden or Lnight, which represent accumulated noise over time and allow evaluation of the impact of noise under prolonged exposure conditions. Read more...
