Descrição

This paper presents the specificities and results of a cost-effective continuous monitoring system
that was designed specifically for wind turbine noise analysis. The system utilizes Class 1 sound
level meters, which are synchronized with other data sources such as audio/video recordings
and meteorological data from local stations. The results are published on a web platform in near
real-time, allowing for the identification of specific noise events and the automatic control of
relevant parameters. The system can detect tonal characteristics using the ISO/TS 20065:2022
method and amplitude modulation, both of which are factors typically associated with wind turbine
noise discomfort.
