Televisions and radios should all be made so radio and TV stations can’t boost the volume when commercials come on.
Back in 2010, President Obama signed a law to stop it in the U.S.;
President Obama has signed a new law requiring TV broadcasters to back down on the volume of those pesky commercials that suddenly blast your eardrums.
But the laws don't take effect until December of this year. I know the law in Canada is supposed to take effect in September 2012. They won't be allowed to boost the volume but we still get it now. The changes can't come soon enough. It's enough that as it is we are paying to watch commercials instead of TV programs (as it is we get about 20 to 21 minutes of a half hour program) so we don’t need those commercials blasting out.
