Game Sound
Turn up the volume. Do you hear a "dunk" when the red square hits an obstacle?
How to Add Sounds?
Use the HTML5 <audio> element to add sound and music to your games.
In our examples, we create a new object constructor to handle sound objects:
Example
 function sound(src) {
    this.sound = document.createElement("audio");
    this.sound.src = src;
    this.sound.setAttribute("preload", "auto");
    this.sound.setAttribute("controls", "none");
    this.sound.style.display = "none";
    document.body.appendChild(this.sound);
    this.play = function(){
        this.sound.play();
    }
    this.stop = function(){
        this.sound.pause();
    }
}
 To create a new sound object use the sound constructor, and when 
the red square hits an obstacle, play the sound:
Example
 var myGamePiece;
var myObstacles = [];
var mySound;
function startGame() {
    myGamePiece = new component(30, 30, "red", 10, 120);
   
 mySound = new sound("bounce.mp3");
    myGameArea.start();
}
function updateGameArea() {
    var x, height, gap, minHeight, maxHeight, minGap, maxGap;
    for (i = 0; i < myObstacles.length; i += 1) {
        if (myGamePiece.crashWith(myObstacles[i])) {
            mySound.play();
            myGameArea.stop();
            return;
        } 
    }
...
}

Background Music
To add background music to your game, add a new sound object, and start playing when you start the game:
Example
 var myGamePiece;
var myObstacles = [];
var mySound;
var myMusic;
function startGame() {
    myGamePiece = new component(30, 30, "red", 10, 120);
    mySound = new sound("bounce.mp3");
    myMusic = new sound("gametheme.mp3");
    myMusic.play();
     myGameArea.start();
}
