  1. In order to reduce the musical residual noise and the background noise, a speech enhancement method based on masking properties of the human auditory system is described. this method uses bark wavelet packet transform to simulate the frequency feature of human auditory model to get the threshold

    本文以最大限度減少殘留噪聲和背景噪聲為目的，採用bark子波分析的方法模擬人耳基底膜的頻率分析特性來進行語音增強，重點進行模擬人耳聽覺掩蔽效應來確定除噪閾值的研究。
  2. Effect of spatial separation in azimuth on the threshold of forward masking in time domain

    聲源空間分離對向前時域掩蔽閾值的影響
  3. Choose the frequency from 14 to 16 bark as the embedding positions which below the masking threshold. then change the dct coefficient with the certain strength of

    選用中低頻14 16bark段在掩蔽閾值以下的頻率分量作為嵌入點，對該嵌入點的dct系數以一定嵌入強度作修改來實現秘密信息的嵌入。
  4. The sinusoidal modeling based on matching pursuit is studied in this thesis, and the concepts of dynamic masking threshold and perceptual gradient are proposed as well as the algorithm of sinusoidal modeling with perceptual gradient

    研究了基於匹配跟蹤的正弦建模問題，提出了動態掩蔽閾值、感知梯度等概念，以及感知梯度正弦建模演算法。
  5. This thesis presents a new audio digital watermark algorithm based on has model. the steps : first, it classifies the signals through fft ; second, calculating the tones, noise and the overall masking threshold of different phases through has, and changing the energy value of tones which are more than that of the overall masking threshold to embed the watermark information

    提出了一種基於人類聽覺系統（ has ）模型的音頻數字水印演算法，該演算法首先對信號進行分段離散快速傅立葉變換（ fft ） ，再根據人類聽覺系統模型計算出各段的類純音、類噪音以及各段的總體掩蔽閾值，通過改變大於總體遮蔽閾值的類純音的能量值來嵌入水印信息。
  6. 1. speech enhancement method based on masking properties of the human auditory system is described. in this paper, a threshold is got through simulating the frequency of human auditory in order to reduce the musical residual noise and the background noise

    在閾值法除噪中閾值確定是極為重要的環節，本文模擬人耳聽覺掩蔽效應來確定閾值大小，以有效的掩蔽殘留的音樂噪聲和最大限度的保留語音。
