摘要 在声学中,前掩蔽是指前一个声音作用时对后一个声音的辨别和感受造成的妨碍.它对人类和动物的声音感知和定位具有重要意义.前掩蔽效应受多种刺激参数的影响和调节.目前人们认为前掩蔽是外周的非线性和中枢水平线性整合的结果,其中神经抑制在前掩蔽的产生中起着重要作用,这种作用主要是γ-氨基丁酸能介导的.此外,非神经性原因等也起着一定的作用. In the auditory system,the detectable of a signal （or probe） is reduced if the signal is preceded by another stimulus called the masker, This phenomenon is known as forward masking. It plays an important role in many auditory phenomena, such as sound apperceive and localization. Forward masking is affected and regulated by many stimulus parameters. Many researches support the ideas that forward masking can be described in term of peripheral nonlinearity followed by linear temporal integration at higher levels in the auditory system. Neural inhibitory play an very important part in forward masking, and this effect is mostly caused by GABA.
