Difference of the Sound Levels Among 15 Japanese Terrestrial and Digital Satellite TV Broadcasting Channels

Document Thumbnail

Towards better sound services for elderly listeners, we investigated, for the first time, the sound levels of 15 Japanese terrestrial analogue broadcasting channels and digital broadcasting channels including NHK and the Commercial broadcasting Bureaus. The results show that (1) the daily averaged sound level of the terrestrial channels was –6.1 dB with 4 dB higher than that of BS digital channels, (2) the maximum level difference of the averaged sound levels between main programs and advertisements inserted in the programs was 15 dB and (3) the average level difference was 2.9 dB. These results imply that there exist perceptually significant problems for elderly viewers.
