Unlike Radio, Televison ads usually sound louder than the program they are in. Radio stations generally compress their whole signal with the aim of creating a consistent listening environment for the listener. But TV ads usually appear louder than the program because of the wide dynamic range in many TV programs for mood and effect, contrasted with the desire for advertising cut-through during the ad break.
The ABA recently investigated the phenomenon of louder TV ads in response to audience complaints, and has decided that something needs to be done about the problem. The ABA has proposed “a new code of practice to cover the loudness of advertisements relative to adjacent programming.” The code will be developed in consultation with TV industry body FACTS.
