Apart from the fact that advertising is too frequent. It is always so loud when compared with the sound in the programmes. I almost always have to reach for the remote control to turn down the sound or mute it completely.
The Advertising Standards Agency (ASA) receives hundreds of complaints each year and yet they are found to be within the rules. Currently, the BCAP TV Advertising Standards Code states that: “ads must not be excessively noisy or strident.
The problem arises in the way that the sound is measured. When testing the level of sound it is the peak volume that is measured. However, advertisers in an attempt to make the advert as attention grabbing as possible compress the sound making the quite sounds louder but keeping the peak sound levels within the rules. The result is a sound that is subjectively louder than it would be if it had been recorded naturally.
