javascript addEventListener-垃圾收集

如果我创建了一个人为数量的音频，向每个音频添加事件侦听器，但从不删除它们，我是否存在内存泄漏？

/* creates infinite number of audios
* note: while(true) would freeze the browser */
function createAudio() {
    var audio = new Audio();
    audio.addEventListener("waiting", function(event) {
        console.log("will never execute");
    });
    window.setTimeout(createAudio, 0);
}
createAudio();
