So I would really like to add sound to my door when it opens and closes (two sounds) but I don't know how to

This is the script that I'm dealing with:

pragma strict

private var guiShow : boolean = false;

private var enter : boolean;

var isOpen : boolean = false;

var door : GameObject;

var rayLength = 10;

function Update() { var hit : RaycastHit; var fwd = transform.TransformDirection(Vector3.forward);

 if(Physics.Raycast(transform.position, fwd, hit, rayLength))
 {
     if(hit.collider.gameObject.tag == "Door")
     {
         guiShow = true;
         if(Input.GetKeyDown("e") && isOpen == false)
         {
             door.GetComponent.<Animation>().Play("open");
             isOpen = true;
             guiShow = false;
         }
         
         else if(Input.GetKeyDown("e") && isOpen == true)
         {
             door.GetComponent.<Animation>().Play("close");
             isOpen = false;
             guiShow = false;
         }
     }
 }

 else
 {
     guiShow = false;
 }

}

function OnGUI(){ if(guiShow == true) GUI.Label(new Rect(Screen.width/1.9 - 75, Screen.height - 100, 150, 30), "Use door"); }
