How to add sound when a door opens in unity 3d?

i have a script that can make a door open but i don’t have any sound.

here is the script

var smooth = 2.0;
var DoorOpenAngle = 90.0;
private var open : boolean;
private var enter : boolean;

private var defaultRot : Vector3;
private var openRot : Vector3;

function Start(){
defaultRot = transform.eulerAngles;
openRot = new Vector3 (defaultRot.x, defaultRot.y + DoorOpenAngle, defaultRot.z);
}

//Main function
function Update (){
if(open){
//Open door
transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, openRot, Time.deltaTime * smooth);
}else{
//Close door
transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, defaultRot, Time.deltaTime * smooth);
}

if(Input.GetKeyDown(“e”) && enter){
open = !open;
}
}

function OnGUI(){
if(enter){
GUI.Label(new Rect(Screen.width/2 - 75, Screen.height - 100, 150, 30), “Press ‘E’ to open the door”);
}
}

//Activate the Main function when player is near the door
function OnTriggerEnter (other : Collider){
if (other.gameObject.tag == “Player”) {
enter = true;
}
}

//Deactivate the Main function when player is go away from door
function OnTriggerExit (other : Collider){
if (other.gameObject.tag == “Player”) {
enter = false;
}
}

if any one can make a new script of add on to mine… that would be awesome. thanx!!

private void playSound(Transform transform, AudioClip clip)
{
var soundObject = new GameObject(“Sound Object”); // Creating new game object to play sound
AudioSource audioSource = soundObject.AddComponent(typeof(AudioSource)) as AudioSource; // Attaching audio source to the game object
audioSource.volume = 1f;
audioSource.pitch = 1f;
audioSource.clip = clip;
soundObject.transform.position = transform.position; // positioning sound object to the doors position
audioSource.Play();
Destroy(soundObject, clip.length + 0.1f); // Destroying sound object
}

i hope this help.
