Abstract (in Japanese) (See Japanese page) 
(in English) The bit rate of a 22.2 multichannel sound (22.2 ch) signal meeting broadcast quality was investigated by performing a subjective evaluation. 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. A bit rate meeting broadcast quality was found to be about 1.2 Mbps from the obtained results.
