摘要
采用了常用的客观评价参数对许多车辆关门声样本进行了分析,并在尖锐度随时间变化曲线的基础上,提出了尖锐度溢值这一指标。经客观分析和主观评价试验表明,尖锐度溢值能够更好地反映视频图信息,与主观偏好性的相关性更好,可以代替峰值尖锐度作为关门声的客观评价指标。
In this paper,the sound quality of lots of door closure sounds was evaluated by using traditional evaluation parameters.Based on the curves of sharpness vs.time,sharpness exceedance was recommended to evaluate the sound quality of automobile door closure.By objective analysis and subjective evaluation,it is proved that sharpness exceedance can reflect more information of time frequency domain,has better correlation with subjective preference,and can be used as a substitute for sharpness in an objective evaluation.
