摘要
HHT方法是一种针对非线性、非平稳信号行之有效的分析与处理方法,它具有自适应性强、高效且希尔伯特谱分析可清晰表明能量随时频分布等特点。该文在分析石方爆破噪声产生机理的基础上,利用HHT方法分析了有关爆破噪声记录,探讨了石方爆破噪声的时频特性。
HHT（Hilbert-Huang Transform） provides a very useful and effective method in analyzing and proeessing non-linear and non-stationary signals. It has eharaeteristies of self-adaptation and good effieieney, and analysis of Hilbert speetrum elearly expressing the energy distribution with time and frequeney in details. This paper analyzes the produee meehanism and eharaeteristies of roeky demolition noise. Moreover, HHT method is used to analyze the time-frequeney eharaeteristies of some demolition noise monitoring reeords so as to gain some valuable eonelusions.
