Abstract (in Japanese) (See Japanese page) 
(in English) We conducted the subjective evaluation test of the TV program audio balance between narration and BGM(Back Ground Music). The test was participated by audio engineers. We measured and analyzed the loudness level of the narration and BGM. We determined the appropriate loudness level difference between narration and BGM on information TV programs. We developed the objective evaluation result display equipment that showed the good loudness difference of the TV program narration and BGM.
