A new method for the evaluation of noise loudness including impulsive sounds is proposed and applied to actual noises. The combination of time-weighting (2TC, the Two-Time-Constants integrator) and frequency-weighting (five existing functions) is examined. Zwicker's procedure for loudness calculation seems to be the best frequency weighting method among the five as far as the 2TC integrator is concerned. The proposed method is used here to evaluate the loudness of various noises with single and repeated bursts of impulsive noise. The loudness of actual noises with impulsive components is evaluated by LAeq and the proposed method. While LAeq could not evaluate the loudness of noises with impulsive components, the proposed method evaluated the loudness of those noises appropriately.
