Automatic estimation of the wind turbine noise with recurrent neural networks
Abstract
There is growing interest in the development of renewable energies, particularly wind power. However, wind turbines generate noise that can affect the sound environment of nearby residents. This study focuses on the isolation of wind turbine noise (WTN) level from the surrounding total noise. Our method is based on a Recurrent Neural Network (RNN) Architecture that captures temporal dependencies in the acoustic signal. This proposal is compared to Non-Negative Matrix Factorization (NMF) that has shown first promising results on a previous study on simulated sound scenes. Our approach relies on simple RNN Vanilla conducted using an end-to-end trained model, Gated Recurrent Network (GRU), and a Long Short Term Memory (LSTM). The training and testing dataset is constructed by superimposing measured background noise with synthesized specific noise; wind turbine noise (WTN), effectively simulating realistic environmental conditions. This study aims to assess the acoustic impact of wind turbines on communities and attempt to control turbine operation using advanced machine learning techniques.
