  1. The noise occultation was significant, and the undertone was the easiest one to be occulted

    噪音對信號的掩蔽作用顯著，其中低音最易被掩蔽。
  2. Theoretical expatiate on general concepts and fundamental principles of information hiding and steganography, also point out possible directions for further research, also analysis the probability of speech as the host carry signal and efficient masking characteristics of psycho - acoustic model, it is shown that : there is an improvement on imperceptibility according to human auditory masking effect

    闡述了信息隱藏技術和隱寫技術的重要概念、基本理論以及廣闊的應用前景。分析了將語音信號作為宿主載體信號的可行性，參考心理聲學模型的特性，得出結論:基於人耳聽覺掩蔽效應的隱寫演算法，在隱蔽性上有很大的提高。
  3. Smr signal to mask ratio

    信號掩蔽比
  4. Speech enhancement method based on masking properties of the human auditory system is used to reduce the white noise in the front - end

    摘要為了提高噪聲環境下說話人識別系統的識別性能，將基於聽覺掩蔽效應的語音增強技術作為預處理器，對語音信號首先進行降噪處理，提高輸入信號的信噪比。
  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. The quantized lp coefficients are replaced by the unquantized lp coefficients in the frequency domain expression of the feel weighted filter. the error signal has more similar envelope shape, and the hearing effect is better than before because the unquantized lp coefficients have more accuracy than quantized lp coefficients

    由於未量化的線性預測系數具有更高的精度，因此，誤差信號通過修正後的感覺加權濾波器以後，具有與語音信號譜更加相似的包絡形狀，從而更好地利用共振峰對誤差的掩蔽效應，達到更佳的主觀聽覺效果。
  7. In natural environment, the signal always masked by interfering noise, that the critical problem is auditory system how to catch the signal under the noise conditions and what neural mechanism underlying it

    現實環境中，所需信號常被空間上分散的噪聲所掩蔽，因此中心問題是聽覺系統如何抽提信號和在掩蔽存在的情況下完成其聽覺任務。
