语音文件中有单频噪声，设计高频滤波器和低频滤波器进行语音滤波(Audio files with a single frequency noise, high frequency filters and low-frequency filter design for voice filtering)

阈值法实现灰度图像分割，效果不错，可行，可以借鉴(Threshold method to achieve gray-scale image segmentation, the effect of a good, viable, can learn from)

通量数据足迹分析，可查看最大贡献源区。以及数据质量分级(analysi footprint)

说明：  Fm 的调制和解调 可以在matlab直接运行，包含模块文件(Fm modulation and demodulation can be run in matlab directly, including the module file)

这个是一个很详细的介绍了声学测量的内容和方法，是西工大的教学材料，希望对学习心理声学的同学有帮助。(This is a very detailed description of the acoustic measurement of the Neirong and the method is NPU teaching materials, Xi Wang students learning psychoacoustic help.)
