AB  - The bit rate of a 22.2 multichannel sound (22.2 ch) signal meeting broadcast quality was investigated by preforming several subjective evaluations. 22.2 ch is currently planned to be transmitted by MPEG-4 AAC (advanced audio coding) in 8K Super Hi-Vision broadcast. A subjective evaluation of the basic audio quality of a coded 22.2 ch signal was carried out using 49 stimuli made from a combination of seven bit rates and seven contents. Moreover, a subjective evaluation at two different listening positions and that of a downmixed 5.1 ch signal were also carried out for comparison with that of a 22.2 ch signal at the sweet spot. A bit rate meeting broadcast quality was found from the obtained results.
