play shot sound

is anyone know how to activate sound when the user click on the left mouse???

using UnityEngine;
using System.Collections;

public class playerAttack3Easy : MonoBehaviour {

	public GameObject target;
	public float attackTimer;
	public float coolDown;
	// Use this for initialization
	void Start () {
		attackTimer = 0;
		coolDown = 2.0f;
	}
	
	// Update is called once per frame
	void Update () {
		if(attackTimer > 0)
			attackTimer -= Time.deltaTime;
		
		if(attackTimer < 0)
			attackTimer =0;
		
		if(Input.GetMouseButton(0)){
			if(attackTimer ==0){
				Attack();
				attackTimer = coolDown;
			}
		}
	}
	
	private void Attack(){
		float distance = Vector3.Distance(target.transform.position, transform.position);
		
		Vector3 dir=(target.transform.position - transform.position).normalized;
		
		float direction = Vector3.Dot(dir, transform.forward);
		
		Debug.Log(direction);
		if(distance<7){
			Debug.Log(distance);
			if(direction>0){
				enemyBar3Easy eh = (enemyBar3Easy)target.GetComponent("enemyBar3Easy");
				eh.AddjustCurrentHealth(-25);
			}
		}		
	}
}

I’m just a newbie in this area…
