The objective of this study is to create an acoustic map of the campus main campus of the Federal University of Santa Maria, for the purpose of updating the mapping carried out in 2013, based on measurements and simulations using the method of measuring values for environmental monitoring of sound levels. The measurements follow the recommendations of the NBR 10151:2019 standard. The distances between the measurement points were also considered in computational simulation, generating noise maps with isolated points, representing the in-situ monitoring. In the study, data from the same measurement points obtained in simulations from 2013 and 2024 were compared, allowing the evaluation of temporal and methodological variations. The results show that the applied method has a variation of ±0.2 dB between measured and simulated values, and that the recorded levels exceeded the limits established by the Brazilian standard by up to 22 dB.The objective of this study is to create an acoustic map of the campus main campus of the Federal University of Santa Maria, for the purpose of updating the mapping carried out in 2013, based on measurements and simulations using the method of measuring sound level in environmental monitoring.
