Web Audio API, events?

Is it possible to add event listeners to web audio api sounds? I've been looking for an event or trigger for when a sounds completes but can't find anything. Here is how I imagine it would work:

soundSource = context.createBufferSource();
soundBuffer = context.createBuffer(audioData, true);
soundSource.buffer = soundBuffer;
soundSource.connect(volumeNode);
soundSource.addEventListener('ended', function(e){
    console.log("ended", "", e);
}, false);
soundSource.noteOn(context.currentTime);
