    Can anyone help me

    I'm an art student making a scale model of a fromula 1 car. The car will not be mechanical however i want to give a realistic as possible experience to the viewer. For this i intend on adding a rumbleseat and fan to give the sense of movement and speed. The problem arises in the fact that i want to link these up to correspond with the decibels produced by the engine noise. I.e the louder the sound of the engine the faster the fan will spin.

    If you can use a DC motor for your fan, you can use PWM ("Pulse Width Modulation" to control fan speed. Input to the PWM can be any of several available VU meter circuits.
