http://www.dolby.com/consumer/technology/dolby-volume-works.htmlHow Dolby Volume Works
A Consistent Problem
The biggest annoyance for home viewers and listeners has been the significant differences in volume levels as you switch between channels or sources on your televisions and in your home entertainment systems. Variances in volume levels in DVD and Blu-ray Disc™, digital music files, compact discs, and broadcast entertainment programming each compound the problem, forcing you to reach for the remote controls to adjust volume.
Once the volume is turned down, a second problem arises. Human hearing is sensitive to human voices at all sound levels. At lower volumes, people can decipher mid-range sound, but high- and low-frequency sounds are lost. Adding to the complexity is the fact that most content that you listen to or watch is rich with sounds that have different levels—and these levels need to balanced with the
main content.
