FIA president Jean Todt has promised to look into improving the sound of Formula One's new engines but dismissed a change in the rules demanded by some stables.
Todt, the head of the world sport's governing body, says those who're complaining about the lack of noise from the engines are more vocal than those in favour.
However he says he's ready to meet with reigning world champion Sebastian Vettel, who bluntly swore when asked about the sound of the new engine.
Todt says Vettel made a negative comment about the engine noise, but not on the engines.
The Frenchman says for the rules to be changed mid-season it would require the unanimous approval of all teams.
