'Calm Act' regulating TV commercial volume levels now in effect

A nuisance that has bothered television viewers for years is now a thing of the past. The Commercial Advertisement Loudness Mitigation Act, or CALM, goes into effect today. The federal law promises to regulate the volume of television commercials which,...

I'm saving the number to my phone now. That's right tv ads... after years and years of annoying me repeatedly, waking my *** up, and even scaring my dog I finally have a chance at revenge. I'll be watching quite a bit of tv during the week. We can take shifts on national channels too if anyone wants

They should really make a commercial for this phone number too (if one doesn't already exist). Not alot of people will even know about it, let alone remember it.

With DVR and a mute button, most ppl dont even pay attention to comercials anymore. Unless they are the SuperBowl comercials. Then everyone watches those. Personally I will either mute my TV or switch over to the Xbox during a comercial. I work in retail so Im pretty much unfazed by the comercials of today. They are too loud with too much fine print. Quick blurbs of information is about all they are anymore. It used to be fun to see what new comercial would come out, especially at christmas. Im sure a few still remember the old Norelco xmas comercial. Untill we see a change in HOW comercials are presented, most ppl will continue to ignore them.

Great,
Now can we get a law like that for video streaming ads on the internet?

I've read that it actually isn't that commercials are broadcast so much louder, but that TV shows keep their volumes well under the max limit in order to "volume spike" at significant moments(car chase, shoot out, etc..) to make them seem more intense. Commercials simply ran at the max limit with no deviation.

Seems a bit silly to make a law giving that the above is the case. Why not just force stations to do away with volume spiking for effect. It would make commercials seem much more normal and the entire programming could be adjusted once; as opposed to super low volume conversation, insanely high music moment in TV, then super lower volume moment leading to super high (seeming) commercial.

Seconded! Some of those streaming add volume fluctuations can be downright maddening!

Good points Guest.

My TV does have a bit of sound compression built-in to it, not a whole lot tho. It will try to flatten the peaks and valleys in audio for a more consistent sound. Transitioning from a talk-show to a commercial with music and an announcer will even still has me reaching for the remote to give the volume two or three clicks down. I'm no audio engineer, but I think the problem is that you cannot predict the audio levels; if the compression was too heavy a jet might fly by at normal voice levels, or a whisper would sound like regular conversation.

I had once called the cable company to see if there was anything that they could do on their end, and since only the tv programing was regulated there was nothing they could do. I suppose this gives them some control and power now.

http://en.wikipedia.org/wiki/Loudness_war very related.

Yes! Also why does the video compression look better in the ads than it does for the actual content you intend to watch??

Could always do away with adverts all together.

I don't like them, I don't want to look at them and they just waste my time. I've probably spent about 400+ hours watching adverts in the course of my entire life.

You're trolling right? Nobody is that... ummm... "unaware".

I can honestly say advertising has never sold anything to me.

It would be nice if the UK adopted something like this also. I've had my fair share of diving for the remote at the start of an ad break to avoid the intense volume.

I sold my tv because I was sick of the ads and the loudness of them... one commercial blew me out of my chair pratically... thats it I unplugged and and 2 yrs later sold it..

I netflix now..

When I had TV I just fast forwarded through commercials.

Now I only have to put with ads on Hulu Plus.

This is a bunch of busybodism by the government. When will everyone learn that the government can't solve all of their problems...

The trouble is, with the new digital sound technology at their disposal, TV stations can really crank up the volume without running afoul of the FCC, since DTV supports a much wider dynamic range than analog broadcast.

Even way back when, the commercials would always blast you out of, "your silent reverie". It wasn't accomplished by turning up the volume. It was illegal to modulate the signal past 100%. So...., they slapped a compressor on the sound when the commercials were on, which placed all the sound bandwidth at 100% modulation, but no more...

The compressor "limits" the signal on the high volume side, and brings up all the soft sounds to near the upper level.

I've also read that it's not the volume so much as the sound shaping that makes the commercials seem so intrusive and, therefore, loud. So it's not enough to regulate the volume alone, if the goal is to make commercials easier to live with.

Here you should be thinking, "big EQ push" in the midrange. Human hearing is most sensitive in the vocal ranges, say from maybe 500Hz to 2000Hz. So, if you put a "hump" centered @ about 1000Hz on the equalizer, the vocals will " cut through the mix".

"Sound shaping" is a term often associated with, (but not limited to), audio equalizers, as the sliders form rough "shapes" on the face of the device.



If you aren't already familiar with these terms, investigate "Fletcher-Munson loudness curves", "audio equalization", "dynamic range", and "audio compression".

Understanding how those 4 factors operate in concert, (pardon the pun), will give you the "big picture" as to what is going on with respect to perceived loudness.
