A method of detecting abnormal sounds affecting the road traffic noise has been proposed. This method uses noise levels L(i)(i=1, 2, …) sampled in time series and their differenceΔL(i)(=L(i+1)-L(i)) that must satisfy the necessary conditions to be the road traffic noise. However, the method has been...
