摘　　要：提出了一种基于心理声学模型的广播音质实时监测方法,该方法利用软件模拟心理声学模型算法,考虑到人耳对音质的心理感知特性,以测试HD Radio系统不同节目的音质变化情况。提出的基于心理声学模型的广播音质实时监测方法,克服了SNR测试不能反映人耳实际感受、测试者主观打分不能保证监测的实时性和反复性的缺点,具有广泛的应用前景。A real-time quality monitoring method for broadcast based on psychoacoustics is proposed, which using software simulation psychoacoustic model algorithm, taking into account the human ear＇ s psychological characteristics. This method is going to overcome the disadvantages about that SNR test doesn＇ t reflect the actual feelings of the human ear and the subjective test can＇ t guarantee the real-time monitoring and repeated, which has broad application pros- pects.
