The end of blaring TV commercials

[Ivan Seeking]

The FCC passed the Commercial Advertisement Loudness Mitigation Act Tuesday to control TV commercial volume

Get ready to not jump out of your seat and fumble for the remote every time a commercial comes on TV -- the Federal Communications Commission (FCC) is finally going to make commercials the same volume as entertainment/news programming...

YAY! I guess this means I won't have to build that smart-sound device I've been planning to make for the last twenty years. This is just another example of the fact that procrastination pays. After only twenty years, the problem took care of itself.

I'll be glad to see this take effect. My wife is very quick to turn the volumn down during commercials but always 'forgets' to turn it back up. Of course, this doesn't happen when her shows are on.

Ivan, maybe you could create a phone tool to nuke telemarketers instead? I'm sure that nobody would mind if you take that request too literally. :tongue:

I never realized that we're married to the same woman.

I'll get right on that one! Check back in about twenty years and I should have something.

Just about every TV I have owned for the last 10 years has done this automatically. Still, it's about time.

 

[turbo]

I hope this comes true. (I have doubts, given the crappy levels of regulation that we see in other areas.) I don't watch too much TV aside from the local and national news, but commercials give me a headache. Most of them are about drugs that can kill you, cause liver failure, or make body-parts fall off, but they are all 'way too loud.

I've never seen a smart sound system that actually worked. And it wasn't an option on the new TVs we considered or the one we bought [I assume because they don't work?].

Anyway, mine would have worked.

I always wondered, at least in the last 5-10 years, if the majority of the difference in volume came from the fact that most programs/movies/etc in digital cable are broadcast in 5.1, and the change in power level comes from the fact that when it goes to a commercial those are usually broadcast in stereo.
With my sony receiver I notice a difference in the output from a single speaker when i change from 5.1 to 2.0 at the same volume level so I just figured that is what it was for everything else. Maybe I'm wrong.

I had been reading about this and was really getting tired of having to turn the sound down or off during commercials.

Aaargh, not until 12-2012?

Don't worry Evo, you have this to look forward to, lol:

The 2012 phenomenon comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on December 21, 2012.[1][2][3][4] This date is regarded as the end-date of a 5,125-year-long cycle in the Mesoamerican Long Count calendar.

and...

A New Age interpretation of this transition is that this date marks the start of time in which Earth and its inhabitants may undergo a positive physical or spiritual transformation, and that 2012 may mark the beginning of a new era. Others suggest that the 2012 date marks the end of the world or a similar catastrophe.

Rhody...

 

[Ivan Seeking]

Holy cow! I didn't think about that. Talk about a sneaky trick.

 

[Jimmy Snyder]

Once that volume goes down, people won't be able to hear the commercials from the toilet anymore and will stop buying fake alligator purses with 3 easy payments. It will cause immediate economic collapse. The Mayans knew this.

 

[LURCH]

I've been hearing about this legislation for some time, and I really have my doubts that it can make any real difference. The people recording the commercials don't know what levels the studios are using to record their programs, and certainly can't afford to record at different levels for each TV show during which their commercial might air. So, they will just record at the loudest level they can, to make sure their commercial is not quieter than the hsow.

I just don't think there is any way this could be done, and I also don't see any way this law could be enforced.

 

[turbo]

The mute button on my TV remote is probably the most worn-out button. Did the Mayans predict this? Huh?!

Just taking a SWAG here, but I don't think the control would be done at the recording level. It will occur at the broadcast level.

I had read an article about this last year, the loud commercials are deliberate to get your attention. I don't know if I can find the report, too much junk on the internet.

I'll go with Lurch's argument. There is already a limit to the audio level, namely 100% modulation of the audio part of the transmitted data.

Human hearing is not a system with a linear response. The people that produce commercials just use the same skill set as the people who produce pop records - they have figured out how to make a given amount of audio power, measured objectively in an electronics lab, sound as loud as possible. The trick is to distort the audio to make it sound "louder", but without making it sound obviously "distorted".

Most people who want to record their own music discover this phenomenon when they find their CDs don't "sound as loud" as commercial ones, even though the peak levels of the recorded signal look the same on a graph.

 

[Astronuc]

I just hit the mute button and leave the room.

I thought TiVo developed a way to block commercials, or skip them, which got them in trouble with the commercial TV. A friend used to record shows for later viewing, and he was able to skip or eliminate commercials for a while. Otherwise, we fast forwards through the commercials.

The best solution is to stop buying anything that is advertised.

How do you know they are always operating at the limit? Perhaps the amplitude is source dependent.

Are you saying there's an "AlephZero covers Led Zeppelin" CD out there?

Dynamic range compression is used. It essentially increases the volume of the quieter parts. While the peak levels remain the same, the average level is increased dramatically. In the most extreme cases, there is little to no difference in the peak and average levels. This has been a real problem in commercial music for years, resulting in an almost complete lack of dynamic range.

For digital TV systems, the amplitude range is built into the digital encoding used. To take the simpler example of an audio CD, the signal can't go "below -32768" or "above +32767" by definition.

All analog TV broadcasting systems currently in use, except one, use frequency modulation for the audio signal, which again has a "built in" amplitude limit (though explaining why would take a very long answer), and the one exception is only used in France.

Ok, here is the simple version of the answer.

Why are TV commercials louder than the show?

Ask any TV station this question and you’ll get the same answer, “the commercials are no louder than any of the other programming we broadcast — they just sound louder.”

It’s true, the station isn’t turning up the volume when the commercials run, but that’s not the complete answer. Otherwise, you wouldn’t need to reach for the remote to turn down the volume during the commercial break. So what’s really going on here? This gets a little complicated, so stick with me on this.

The Federal Communications Commission does not specifically regulate the volume of TV programs or TV commercials. However, broadcasters are required to have equipment that limits the peak power they can use to send out their audio and video signals. That means the loudest TV commercial will never be any louder than the loudest part of any TV program.

A TV program has a mix of audio levels. There are loud parts and soft parts. Nuance is used to build the dramatic effect.

Most advertisers don’t want nuance. They want to grab your attention. To do that, the audio track is electronically processed to make every part of it as loud as possible within legal limits. “Nothing is allowed to be subtle,” says Brian Dooley, Editor-At-Large for CNET.com. “Everything is loud – the voices, the music and the sound effects.”

“the commercials are no louder than any of the other programming we broadcast — they just sound louder.” What would one expect an advertiser (politician, used car salesman, crack dealer, . . . .) to say?!

piled high and deep!

 

[AlephZero]

“the commercials are no louder than any of the other programming we broadcast — they just sound louder.”

It's perfectly good science. That's why there are two units for sound intensity, decibels and phons. http://hyperphysics.phy-astr.gsu.edu/hbase/sound/eqloud.html#c1

This problem was supposedly solved years ago.

The Federal Communications Commission does not specifically regulate the volume of TV programs or TV commercials. However, broadcasters are required to have equipment that limits the peak power they can use to send out their audio and video signals. That means the loudest TV commercial will never be any louder than the loudest part of any TV program.

http://www.msnbc.msn.com/id/17229281/ns/business-consumer_news/t/why-are-tv-commercials-louder-show/

The TV Program producers apparently started putting in at least one louder word or sound just to get advertisers.

Edit from 2007

 

[edward]

AS I read down he link above I see,

Help is on the way! Last month Dolby Laboratories announced it has developed technology to level out the sound differences that take place during shows and between TV programs and commercials. You pick the volume you like and the Dolby software will make the adjustments in real time automatically.

Could it be that Dolby has a patent on the electronics?

 

[Astronuc]

But there is no change in frequency involved here. The range of frequencies in the commercials are the same as the TV programs. They are not shifted by kHz.

I think the signal input for advertisements is slightly greater than for programs. Some channels/broadcasters are worse than others.

Nevertheless - just use the mute button and ignore the commericals.

And I ignore ads in print.

So, they will just record at the loudest level they can, to make sure their commercial is not quieter than the hsow.

Extremely unlikely. Sound editing/mixing is a technical and well developed profession and I find it incredulous that the advertisers and networks don't know exactly what they -and everyone else- are doing.

As mentioned, there is a set dynamic range that everyone has to work with, limited by the signal transmission. So the difference between the commercials and the programs would simply be that the sound levels of certain types of sounds are indexed to different parts of the range. Say, for example, a sound mixer for a tv show had three different sounds to mix: background music, speaking voices and an explosion. He's not lucky enough that they are already at the right sound levels when he mixes them together: he has to pick the levels as he mixes them. On a scale of one to ten, he mixes them at level 2, level 4 and level 8, respectively (made up numbers). He does this so that they sound natural to our ears -- and by the way, I don't notice differences between shows or between channels, so *somehow*, there is standardization in this. Whether that standardization comes from the show editors (say, a sound editor's handbook?), the tv network or the cable company, I don't know. Regardless, the advertiser (generally) has only background music and speech, so he indexes them to level 4 and level 8, respectively and so we get the commercial actually being louder than similar parts of the TV show.

I've also noticed that movies usually have a wider dynamic range than tv shows and perhaps even action movies have wider ranges than rom-coms. This would be done on purpose, to optimize the sound for a louder playback device (my home theater, rather than the tv speakers). But if I'm not in my normal movie watching mode (say, if I'm in bed, watching on a little tv), I'll often manually compress the range, increasing the volume of soft talking and decreasing the volume of loud action. The physical range is the same, of course, but that just means they index the different types of sounds to different parts of the range in movies than for tv.

...and, of course, the explosion in the movie or action tv show is only momentary and most of the show is speaking, so you would want to compare averages, not peaks.
