Particle Sound Emission

How can I play a sound every time a particle is emitted? I'm using a particle emitter to cause lightning strikes, but I want it to play a sound each time.

make a new script and say

function Update()
{
 if(gameObject.particleEmitter.emit)
 {
  audio.Play();
 }
}

and that should work for every frame your lightning particles are emitting... please help me by telling me anything missing, or anything else you might need for this to work if it isn't!

hope that works for you!
