中文摘要	噪声是造成听力损伤的重要因素。针对噪声分析侧重研究噪声源的特性,较少考虑噪声防护需求的现状。从人耳听觉系统的感知特性出发,采用Gammatone分析滤波器组对声音在频域上进行非均匀多子带分解,通过耳谱图、子带能量及通道相关特性,定量计算噪声信号听感知特性,并提出了相应的噪声防护建议。从听感知特性出发分析噪声特征,进而设计的噪声防护方法是一种有效途径。; Noise is an important factor in causing hearing damage. Most noise analysis focuses on the characteristics of the noise source,and few consider noise protection needs. From the perception of the human auditory system,Gammatone filter bank is used to decompose the sound in frequency domain for non-uniform multi-sub bands decomposition; through spectrogram,sub-band energy and channel-related characteristics,the auditory feature of the noise signal is calculated quantitatively and the noise protection recommendations is put forward. Analyzing the noise auditory feature,then noise separation is an effective method to hearing protection.
