Audio To Script help?

Hello Unity,
I'm learning to code in JS (I know its not the best but its a good start) I'm having an issue adding audio to my game-object or will i have to make an audio script on its own & add it to an empty & place that by the object that's getting destroyed? As of right now the object gets destroyed right away then particle get remove 4 seconds after when player hits said object. Script i'm using is below; (This is health for the objects)

Code (JavaScript):

1. // This section is health for the object when hits 0 its destroys itself.
2. var health :int = 8;
3.  
4. function Damage(damage:int){
5.     health -= damage;
6.     if(health <= 0)Destroy(gameObject);
7. }
8.  
9.     // This section is for effect to play when object is destroyed.
10.     var explosion: GameObject;
11.  
12.     function OnCollisionEnter(){
13.         var expl = Instantiate(explosion, transform.position, Quaternion.identity);
14.         Destroy(gameObject);
15.         Destroy(expl, 4); // Deletes the effect after 4 seconds of when object is destroyed.
16.     }
17.  
18.     // This section is Sound (Not working)
19.     var reload : AudioClip;

Thank you if anyone can help me today

Can use this (it plays even after gameobject gets destroyed)
https://docs.unity3d.com/ScriptReference/AudioSource.PlayClipAtPoint.html

or other alternatives,
- disable the gameobjects renderer/collider/etc, instead of destroying, so it has time to play sound, before its destroyed (add delay to Destroy(gameObject, x))
- or add sound into the particlesystem prefab, and have [x] play on awake, so it plays automatically when particle system gets instantiated
