摘要
后处理是电声测量系统获取测量数据过程中的一项重要计算步骤,主要应用于对采集到的各类数据曲线(如频响曲线、阻抗曲线等)或测量单值(如F0、灵敏度等)进行用户所需的各种操作,如算术运算、平滑处理及统计分析等。而后处理算术运算则主要是对采集到的操作数曲线或值进行相应的加减乘除操作,完成曲线的上下平移,得到平移后的值,进而对标准曲线或单值进行校正。其工作模式分为分贝、线性和功率3种,主要运用插值算法对其进行处理。针对上述各类运算法则进行了剖析与仿真分析,可以满足电声测量系统处理数据的不同要求。
Post-processing is an important step in the process of getting metrical data in the electro-acoustic measurement system,it is mainly used for various operations to the collected sound signal curve（frequency response curve impedance curve etc.） or to the single points（F0 sensitivity etc.） in curve,which must meet the need of the users,such as arithmetic operation,smoothing process and statistical analysis.But post-processing arithmetic operations are mostly used to do corresponding operations,such as addition,subtraction,multiplication and division,to the collected operand curve or its values,so as to complete up-down translation to the curve and get the values after translation,and then comes the correction to standard curve or single point value.The working mode of post-processing arithmetic operations is divided into three types,including db,linear and power,the interpolation algorithm is primarily used for data processing.For the the above various algorithm rules,the analysis and simulation on them is proceeded in this paper,and the results show that they can satisfy the different requirements of data processing in the electro-acoustic measurement system.
