The invention discloses an objective evaluation method for the sound quality of an in-vehicle sound box. The method comprises the following steps: acquiring an in-vehicle recording signal and a playing source signal; calculating tone quality objective parameters according to the in-vehicle recording signal and the playing source signal, wherein the tone quality objective parameters comprise a tone quality distortion parameter and a frequency response parameter; and weighting the tone quality distortion parameter and the frequency response parameter according to a preset weight coefficient, and generating and outputting an evaluation result. The invention further discloses an objective evaluation system for the sound quality of the in-vehicle sound equipment, computer equipment and a computer readable storage medium. According to the method, objective indexes corresponding to the sound quality are measured and calculated in the vehicle, and the sound quality of the whole vehicle can be rapidly and effectively evaluated.

    本发明公开了一种车内音响音质的客观评价方法,包括:获取车内录制信号及播放源信号;根据所述车内录制信号及播放源信号计算音质感客观参数,所述音质感客观参数包括音质失真参数和频率响应参数;根据预设权重系数对所述音质失真参数和所述频率响应参数进行加权处理,生成并输出评价结果。本发明还公开了一种车内音响音质的客观评价系统、一种计算机设备及一种计算机可读存储介质。本发明通过在车内测量并计算音质感相应的客观指标,能够快速有效地评价整车音响音质的好坏。
