Pick Up Sound

I'm trying to play a sound when a certain object is collected. Any help would be appreciated.

My Code:

using UnityEngine; using UnityEngine.UI; using System.Collections;

public class PlayerPickUp : MonoBehaviour {

 //public float speed;
 public Text countText;
 public Text winText;
 public GameObject Exit;
 public GameObject spikewalldoor;

 //private Rigidbody rb;
 private int count;

 void Start ()
 {

// rb = GetComponent(); count = 0; SetCountText (); winText.text = ""; }

 void FixedUpdate ()
 {
     //float moveHorizontal = Input.GetAxis ("Horizontal");
     //float moveVertical = Input.GetAxis ("Vertical");

     //Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

     //rb.AddForce (movement * speed);
 }

 void OnTriggerEnter(Collider other) 
 {
     if (other.gameObject.CompareTag ( "Pick Up"))
     {
         
         other.gameObject.SetActive (false);
         count = count + 1;
         SetCountText ();
     }
 }

 void SetCountText ()
 {
     countText.text = "Collect 245 Cubes: " + count.ToString ();
     if (count >= 245)
     {
         winText.text = "Level Complete!";
         Exit.gameObject.SetActive (true);
         spikewalldoor.gameObject.SetActive (false);
     }
 }

}
