1/3倍频程分析。有需要做这方面研究的同志们可以好好看一下。-1/3 octave analysis. There is a need to do research in this area can be a good look comrades.

对振动信号进行频域处理包括：信号谱分析，matlab中没有的窗函数处理，三分之一倍频程处理-The vibration signal of the frequency domain includes: signal spectrum analysis, the window function in MATLAB no, 1/3 octave processing,,,

基于声压有效值等效的1/3倍频程分析MATLAB程序，通过此程序可得到任意一段脉动信号的1/3倍频程bar图。-Analysis of MATLAB programs Based on sound pressure rms equivalent of 1/3 octave, this program can be obtained through the 1/3 octave bar diagram for any period of pulsating signals.

直接输入wav的声音文件，可得到1/3倍频程和瞬态声压级(1 / 3 octave and transient sound pressure level)
