该代码支持多个哔哔声的排序，以及频率的逐渐变化('ramp'标志)。下面给出了两个例子。

<script>
var audioContext = null;
var oscillatorNode = null;
var stopTime = 0;

function beep (frequency, durationSec, ramp=false)
{
    if (oscillatorNode == null) {
        audioContext = new (window.AudioContext || window.webkitAudioContext) ();
        stopTime = audioContext.currentTime;

        oscillatorNode = audioContext.createOscillator();
        oscillatorNode.type = "sine";
        oscillatorNode.connect (audioContext.destination);
        if (ramp) {
            oscillatorNode.frequency.setValueAtTime (frequency, stopTime);
        }
        oscillatorNode.start ();
        oscillatorNode.onended = function() {
            oscillatorNode = null;
            audioContext = null;
        }
    }

    if (ramp) {
        oscillatorNode.frequency.linearRampToValueAtTime (frequency, stopTime); // value in hertz
    } else {
        oscillatorNode.frequency.setValueAtTime (frequency, stopTime);  // value in hertz
    }

    stopTime += durationSec;
    oscillatorNode.stop (stopTime);
}
function test1()
{
        beep (250, 0.5);
        beep (1000, 0.2);
        beep (550, 0.5);
}
    
function test2()
{
        beep (50, 2, true);
        beep (5000, 2, true);
        beep (50, 0, true);
}
</script>
    
<button onclick='test1()'>Beep!</button>
<button onclick='test2()'>Beep(ramped)!</button>

注意:把这段代码放在你想要出现哔哔声的地方。 并且记住指定存储哔哔声的目录或文件夹(源)。

<script>
//Appending HTML5 Audio Tag in HTML Body
$('<audio id="chatAudio"><source src="sound/notify.ogg" type="audio/ogg"><source src="sound/notify.mp3" type="audio/mpeg"><source src="sound/notify.wav" type="audio/wav"></audio>').appendTo('body');

$('#chatAudio')[0].play();
</script>

我在我正在开发的社交媒体中实现了这一点，它的工作发现，聊天时像facebook一样的通知，通知你有一个新的聊天消息

使用CSS，你可以这样做，如果你添加以下样式的标签，但你需要一个wav文件:

<style type="text/css">
        .beep {cue: url("beep.wav") }
</style>

var body=document.getElementByTagName("body");
body.className=body.className + " " + "beep";

根据Houshalter的建议，我制作了这个简单的音调合成器演示。
