Check for vaccum leaks. Specially small hoses as sound disappears at higher speed

I think at higher speed sound will come but due to air pressure it is not audible...can there be any fault in silencer ???

Please check alternator and all belts with sathoscop, some time alternator noicy, and cracks in belts.

But when car is stopped and we press accelerator paddle then sound also comes... I think alternator should sound during running of car...

there is a part connected to the throttle body known as auto choke, get that opened from your mechanic, there is a small bearing assembly in it, get that cleaned with petrol till it moves without any blockages. this worked for me and the whistling sound vanished.
