Following Sunday's Australian Grand Prix, Ron Walker, chairman of the organising company that stages the race, complained to close friend Ecclestone about the lack of sound.

Speaking to The Daily Telegraph, Ecclestone added: "I think let's get the first few races out of the way and then maybe look to do something. We can't wait all season. It could be too late by then."
