Don't know much about it, there're some gadgets for automatic volume control the loud TV commercials
I think that's a very good idea. Of course, they would never have been thought necessary if adverts really were no louder than the programmes.
Personally, I get round it by pre-recording and then skipping through the adverts. It's inevitable, though, that I unintentionally hear some bits of adverts.
I wouldn't mind adverts so much if they were even in the slightest entertaining. Those meerkats just before Coronation Street can be quite funny, though. If we ever have children, I'm going to call the boy Bogdan!
