By discussing the existing voice and audio encoding technology, the thesis designs an CNG algorithm which is based on the mask effect theory.
本文在充分讨论现有语音及音频编码技术的基础上，提出了一种基于掩蔽效应的CNG技术，并实现了该算法。
Experiments on simultaneous mask effect where tones were masked by narrow-band noises with different SPL showed that the masking curve could be approximated as two segments of straight line.
不同声压级下窄带噪声对纯音同时掩蔽效应的实验结果表明：掩蔽曲线可以用两段直线来近似。
