Convention Paper

A Survey of Broadcast Television Perceived Relative Audio Levels

Authors: Hanna, Chris; Easley, Matthew

AES Convention 127 · Paper 7896 · October 2009

Abstract

Perceived television volume levels can vary dramatically as audio changes both within a given broadcast channel and between broadcast channels. This paper surveys the broadcast audio levels in two large metropolitan areas (Atlanta and Boston). Both analog and digital broadcasts are monitored from cable and satellite providers. Two-channel perceived loudness is measured utilizing the ITU BS.1770 loudness meter standard. Statistical data is presented showing the severity and nature of the perceived loudness changes. Finally, dynamic volume control technology is applied to the most severe recordings for perceived loudness comparisons.
