Loudness determined by power summation.The predicted overall loudness of steady, broad-band noise is usually computed by summing weighted loudnesses of sub-bands of the noise intensity (mean-square pressure) spectrum. It is proposed, instead, that the overall loudness should be computed by summing weighted intensities of sub-bands ('critical bands') of noise and then obtaining the loudness of the sum. This method seems to yield better agreement with published loudness judgments than does the usual method. It appears that the proposed method should also yield better agreement with annoyance judgments than does the 'perceived noise' method of Kryter.
