Ear-jarring volume discrepancies between television shows and commercials may be a thing of the past if Motley Fool Stock Advisor selection Dolby Labs
We're all familiar with the phenomenon: We're reclining in our Barcaloungers, calmly watching the late show when a commercial comes on and the volume has suddenly increased 10 decibels, causing us to spill our beer as we jump for the remote control. Dolby says its new Dolby Volume technology will make that rude awakening a thing of the past.
The technology is pretty important for Dolby, because systems incorporating its surround sound technology make the experience that much more jolting when it occurs. It might not be as jarring on your rabbit-ears set in the kitchen, but on that 60-inch plasma screen with five, six, or seven high-def speakers pointed at your cochlea, it can leave your ears ringing.
Dolby will unveil its volume control system at the Consumer Electronics Show Monday in Las Vegas, and the company hopes it will start appearing in television sets by year's end.
The difference in volume occurs because programmers try to compress the sound to boost volume without exceeding the limits the government has set. While most televisions today are equipped with circuits that are designed to stabilize the differences between TV shows and commercials, they are not necessarily effective and can still be problematic if the broadcaster fails to properly operate equipment on its end.

Dolby instead offers one chip that would be part of the set's components. (According to some reports, Cirrus Logic
Perhaps another area where it should be investigated is cell phones. Despite advances there, sound quality has never been all that good, but Q Sound Labs
Let's hope Dolby's technology proves popular, if only so that another drop of beer will never be spilled while jumping to turn down an annoying commercial.
