Is the background music too loud?
Danny Cohen, Controller of BBC One blogs about background music and the Vision Audibility project on the TV blog.
"One of the most common complaints to BBC television in recent years has been that some people find it hard to hear the dialogue in our shows.
They cite many reasons for this, the most common among them being background music being too loud.
As a result of these complaints in 2009, Jay Hunt (my predecessor as controller of BBC One) launched an extensive study into why people were experiencing these difficulties.
BBC Vision's Audibility project was a huge undertaking. It involved using our 20,000-strong panel of TV viewers across the age, geographical and social demographic and a good deal of technical experimentation."
