Dolby to Turn Volume Down on Loud Commercials

Dolby DigitalWe can all relate to having been bombarded with an exceptionally loud commercial (or three) while calmly watching television at an otherwise normal volume. Dolby hopes to remedy that with a new technology that keeps volume levels more or less the same accross TV channels, programs, and commercials.

Dolby says that the goal of Dolby Volume's aim is to deliver consistent volume levels by modeling how "humans perceive audio" to eliminate variable loudness in the audio stream. Dolby claims that the system does this automatically without any type of user intervention (aside from the initial setup).

There's no word out yet about how much this new technology will cost, but according to Dolby, it shouldn't raise television set prices by "more than just a few percent." A few percent on a cheap TV set could be quite affordable, but on a high-end one, we could be talking about a few hundred dollars.


  • Wasn't this already done back in the '90's ??

    I remember selling tv's by Mitsubishi and RCA that provided Commercial sound equalization... essentially the audio decoder inside the tv would ensure that sound was kept at a consistant dB level...

    I didn't know this was 'new'?

  • Yeah, I seem to recall something like this. Dolby probably thought that by re-inventing the wheel, they could make a few extra bucks out of an existing technology.
