AB  - There has been both experimental and anecdotal evidence that the low-frequency performance in the ITU-R Recommendation BS.1770 program loudness measurement algorithm could be improved. A listening test with an emphasis on low frequency content was therefore conducted. An attempt was made to analyse the results in octave bands by multiple regression, but larger than expected variability precluded any useful outcome from this method. A simpler regression analysis was therefore performed using several fixed weighting curves and asymmetric integration with a range of time constants. Although the results largely support the present low frequency weighting curve, they also indicate that asymmetric integration provides better program loudness assessment than symmetric integration or high level gating.
