Event Notification to user by playing beep sound in Java Script

Description
This is a common requirement from web application users.

For some events, required beep sound.
That helps the user to identify some event occurrence.

Examples:

3) When User attention is required for some critical action.

This code works even for lower end devices also.

Sample Java script Code

function playBeep() {

    var beepSourceFile = window.beepFilePath;
    var isHTML5 = true;
    /**
     * For lower versions of IE9, isHTML5 value will be false. The beep sound will be played with help of bgsound tag.
     * For IE9 & higher ver of IE, google chrome & firefox, isHTML5 is true. The beep will be played with help of audio tag.
     */
    try {
        if (isHTML5) {
            $("").appendTo('body');
            $('#beepAudio')[0].play();
        }
    } catch (ex) {
        isHTML5 = false;
    }
    //alert('isHTML5:' + isHTML5);

    if (!isHTML5) {
        $("body").append("");
    }
}
