The rock acoustic parameters in this paper include wave amplitude, spectralamplitude, spectral area, spectral density, wave velocity and attenuation coefficient etc.
这些岩石声学参数为波幅、谱幅、谱面积、谱密度、波速度、衰减系数等。

We introduce an optimally-modified log spectralamplitude estimator, which minimizes the mean-square error of the log spectra for speech signals under signal presence uncertainty.
引入了最佳修正短时对数谱估计，能在信号存在的不确定性下最小化语音信号对数谱的均方误差。

This information normally exists in the form of signal amplitude (absolute or relative) frequency or spectral content phase or timing relationships with respect to other signals.
