来自美国迈阿密大学医学院的专家认为，长时间高音量用MP3听音乐可导致暂时性、甚至是永久且不可逆性听力损害（Prolonged listening at loud volume may lead to temporary and later irreversible loss, experts say）。

    如何使用MP3听音乐才不至于损害您的听力？专家建议：“假如您在使用MP3时，您仍能够听到您周围的人谈话，则表明您所设置的音量大小是安全的。假如您将MP3的音量调得太大，以致您不能够听到您周围的人们的谈话，或离您仅2或3英尺远的某人必须大声吼叫才能够引起您的注意时，则表明您所设置的MP3音量已经达到了可以损害您的听力的危险水平”（If you can still hear what people are saying around you, you are at a safe level," he said. "If the volume is turned so loudly that you can no longer hear conversation around you, or if someone has to shout at you at a distance of about 2 feet or 3 feet to get your attention, then you are up in the hazardous noise range）。
