Loudness management for home television viewing

This paper presents dual sensor based loudness management system for television viewing at home environment in compliance with BS1770 loudness measurement standard. The aim of the research was mainly to address the issue of sudden increase in loudness during commercials in between TV programmes. Same approach works for any TV programme as well. The scope of this research reported here was limited to investigate, develop an adaptive loudness control system to create a pleasurable TV viewing environment and to prove efficacy of algorithm functionality by simulations. The novel contributions made in paper are the design and the proof of functional efficacy of the loudness management algorithms using the loudness measurements made through the simple instrumentation set-up in compliance with BS1770 loudness measurement standard.
