The identification and separation of sound sources has ssp218dda-sf always been a difficult problem for acoustic technicians to tackle.This is due to the considerable complexity of a sound that is made up of many contributions at different frequencies.Each sound has a specific frequency spectrum, but when many sounds overlap it becomes difficult to discriminate between the different contributions.
In this case, it can be extremely useful to have a tool that is capable of identifying the operating conditions of an acoustic source.In this study, measurements were made of the noise emitted by a wind turbine in the vicinity of a sensitive receptor.To identify the operating conditions of the wind turbine, average spectral levels in one-third alterna my hair my canvas soaring high volumizing blowout mist octave bands were used.
A model based on a support vector machine (SVM) was developed for the detection of the operating conditions of the wind turbine; then a model based on an artificial neural network was used to compare the performance of both models.The high precision returned by the simulation models supports the adoption of these tools as a support for the acoustic characterization of noise in environments close to wind turbines.
