From a technical standpoint I think this is something pretty difficult to legislate/regulate/enforce.
For example, lets say a company produces a commercial and compresses and normalizes the audio (in simple terms, squash the dynamic range, and set volume to max before clip).
You’re watching a movie which has a wide dynamic range so that soft sounds (like whispers, distant speech, distant gun fire, distant fighter jet, distant explosion, etc.) are soft and loud sounds (like close gun fire, fighter jet fly-by, in your face explosion, etc. are loud. So you have the volume set to a decent level to allow you to hear the soft sounds, and on comes this commercial with compressed and normalized audio, and it blows you out of your chair/bed and everyone runs for the doors.
On the other hand some else is watching a program with compressed and normalized audio when the commercial comes on, so the volume seems to match that of the program they are watching. But then when a commercial comes on that is not compressed and normalized it seems abnormally quite in comparison to the program being watched.
So how is the commercial makers, legislators and regulators to know what volume level should be used and how to specify it in a way that not only solves the issue but is enforceable?
From a commercial producers point of view perhaps it is the program material audio that is too soft? How would you feel about legislating movie audio levels so that the better matched the commercials?
As much as I hate the excessively loud commercials, I prefer carriers to leave the feed unaltered. That goes for both audio and video.
I’ll just keep using my A.L.C (auto level control), mute button, channel button, and DVR skip button, except for the commercials that are not irritating, and worthy of my time, eyes and ears.
