Help With including audio in my script

I have this script attached to a “bomb” in my game and im trying to add a explosion sound whenever the bomb explodes. And im using javascript for my code. I know this is simple but i just cant get it to work right! thank you!

var radius : float = 5.0;    //provides a radius at which the explosive will effect rigidbodies
var power : float = 10.0;    //provides explosive power
var explosiveLift : float = 1.0; //determines how the explosion reacts. A higher value means rigidbodies will fly upward
var explosiveDelay : float = 5.0; //adds a delay in seconds to our explosive object

		function Start () {
		
		yield WaitForSeconds(explosiveDelay);
		var grenadeOrigin : Vector3 = transform.position;
		var colliders : Collider[] = Physics.OverlapSphere (grenadeOrigin, radius);
		
		 for(var hit : Collider in colliders){ 
		 
		   
		     if (hit.rigidbody){
		     
		        hit.rigidbody.AddExplosionForce(power, grenadeOrigin, radius, explosiveLift);
		        Destroy(gameObject);
		        }
		        
		}
	}

Where is the audio part for your script or haven’t you tried to implement it at all?
