AB  - NHK is planning 8K Super Hi-Vision (SHV) broadcasting with 22.2 multichannel sound as a new broadcasting service. The current loudness measurement algorithm, however, are only standardized up to 5.1 channels in Recommendation ITU-R BS.1770. To extend the algorithm beyond 5.1 ch, we conducted a subjective loudness evaluation of various program materials and formats. The results showed that different formats differed only slightly. Furthermore, we measured objective loudness values on the basis of an algorithm compatible with the current algorithm and found that the objective loudness values had a good correlation with the subjective loudness values.
