Las Vegas, NV (January 11, 2007)--Dolby Laboratories, Inc. has rolled out a new technology, Dolby Volume, which addresses loudness issues on television audio. The breakthrough technology, introduced at the International Consumer Electronics Show (ICES) in Las Vegas, solves a leading broadcast television consumer issue--the annoyance of inconsistent volume across channels and programs.

At the CES, Dolby demonstrated the breakthrough audio-processing technology, which is designed to help television makers address the annoyances of inconsistent loudness in broadcast TV. Dolby Volume brings a fundamentally new approach to TV entertainment by delivering consistent volume levels. It models how humans perceive audio to finally eliminate variable loudness when changing channels or programs, without disruptive audio artifacts. It also delivers a robust and vibrant audio experience at low volume by dynamically compensating for the human ear's lower sensitivity to bass and treble sounds as the volume level decreases. These adjustments are automatic and do not require user intervention as the volume changes.

Dolby Volume builds on more than 40 years of pioneering research into human hearing and can capitalize on other loudness control features in the Dolby Digital broadcast system. Dolby expects to commence delivery of Dolby Volume code to integrated circuit manufacturers in Q1 of 2007.
