Development of Combined Noise Annoyance Model Based on the Partial Loudness Model

Many studies have been conducted to evaluate the annoyance of combined noise. However, the previous models were noise source dependent and not considered about the frequency spectrum of the noise elements. For these reasons, this research proposes the new annoyance evaluation model that is source independent and taking account of the frequency characteristics. The experiment had been carried out to the subjects to ask about the annoyance of combined noise with various levels. Aircraft noise and road traffic noise are used as the test sources. Next, the levels of noise sources are converted to the loudness, with the help of Moore's partial loudness model. By evaluating the relationship between the loudness of the noises and the experimental annoyance results with logistic regression, the model that explains the annoyance of combined noise is deducted. To extend the application of this model, other noise sources, such as train noise and wind turbine noise, need to be tested for the validation.
