Is there any way of lowering the advert volume to the average say, of
the programmes?

I am using MythTV by the way although that shouldn't make any difference.

TIA

I thought it was a breach of broadcasting rules to increase the volume
for the adverts. I thought Channel 4 was fined for this. I also
thought the test was changed to a subjective one to prevent
broadcasters increasing compression while maintaining the same
measured volume.

No idea whether adverts are deliberately too loud but many TVs have an
Auto Gain Control which automatically regulates large sound level
differences when turned on.

Do you perhaps have the audio selected for one of the surround sound
options?
I noticed this on some of the Samsung streamed channels, but I could not
figure out how to make it stereo not 5.1 in those channels.
The other thought is that the sound of the programme has the correct
dynamic range, but the adverts are compressed making them sound louder,
since even the quiet bits are loud. This of course is often done
deliberately

Well its not worked has it?

I also notice that hd channels are quieter than SD and radio stations are
mostly louder tan TV channels on freeview.

Those often sound worse than not having it, due to the gain riding effects
you get, a bit like a cheap portable tape machine used to do.

+1
The audio on adverts on many channels are often way louder than the
audio during the programs. The advertisers also play other audio tricks
in order to get noticed such as common doorbell or phone ring tones
within the adverts. The is one advert that is completely silent and it
works so well I cannot remember what it was for :)

There is a maximum volume that the technology can reproduce. Classical
music has a high dynamic range, meaning that the loudness varies greatly
during the piece. If you set a level where the loudest section is not
clipped, the average will be relatively quiet.

So, for classical music, low average volume is necessary to correctly
reproduce the occasional high volume part.

The slight catch is that, with a low average volume, quantisation noise
is greater (or thermal noise, on analogue systems).

Typical pop music has a low dynamic range (everything louder than
everything else) so you can get away with setting the average volume
higher. Talking heads also have a low dynamic range. Setting the
average volume high doesn't lead to clipping, and may marginally reduce
noise.

Adverts are allowed to be 3dB louder (that's twice as loud) AIUI.

Yesterday I was idly flicking through the Freeview radio channels. As it
happens the audio was connected to an oscilloscope. The difference in
levels between channels was very noticeable.

Not sure about that. Twice the power, yes, but an increase (or decrease)
of 3dB is barely noticeable.

Way, way back, Hill Street Blues (Ch4?) always had unbelievably low
audio during the programme, requiring the TV volume control to be set to
maximum. However, the adverts must have been at least 20dB louder,
necessitating a leap up from the settee and a grab for the volume knob.

There's a few newsagents' shops called Hill Street News. There's one in
Bradford called Tong Street News.

You've reminded me to check this and I found it was set to "off" on my
Panny TV. I've just set it to "on" to see if it helps. I suppose if it's
the same thing as what the Panny PVR manual refers to as "Dynamic range
compression".

I find the sound quality is so poor on many programmes these days that I
resort to subtitles to hear what is being said.

+1, except that I have to put it through a HiFi instead, but even then
sometimes can't distinguish it.

I don't usually have trouble with Scottish accents, having listened to
them all my life, but yesterday I finally got around to watching a
televised Fern Brady gig that I downloaded some weeks ago, after finding
some of her contributions to 'The News Quiz' quite funny, but even
through a HiFi found difficulty in understanding some of the 'jokes' -
I quote that word because even those I did understand didn't seem to be
very funny, - partly her vocal range of loudness being predominantly
quiet with occasional shouts, partly her indistinct diction, partly the
use of modern slang. I watched about half of it, but then lost patience
and deleted it.

I'm finding the need for the HiFi more and more, as the sound of speech
often seems as though the mic is buried beneath multiple layers of clothing.
