Dolby Volume is a new technology that will target the issue of inconsistent volume across television channels and programs. It will require no human intervention to work, and “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.

Dolby says, “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…” Dolby Press Release
