In this paper , the author established the model of objective evaluate parameters of sound quality and develope d an objective evaluation system which could give quantitative objective evaluate parameters , such as loudness , sharpness , roughness , psychoacoustics annoyance ( pa ) etc . paper also describes an subjective evaluation investigation ir “ “ hich 16 subjects used pair comparison statistical evaluation methods to evaluate the noise character of room air - conditioners , the results show that there is generality good agreement between quantitative objective evaluate sound quality parameters and subjective evaluation . at the same time an example of application of the technique to improve the noise character of room air - conditioner is offered 此外本文還介紹了一個應用聲質量評價技術改進kfr - 50hw / e2d空調器聲質量的實例,通過對空調器室外機管系、導流罩、出風網等進行改進,空調器的聲質量得到了明顯改善:在室外風量提高164m ~ 3 / h情況下,聲音響度下降16 ,波動強度明顯改善,尖銳度指標也略有下降,作者同時總結了不同改進措施對產品聲質量影響的方式,以期為今后的聲質量改進提供借鑒。

Audio localization technology , a new intersecting subject , touches on such research fields as psychoacoustics and physiology , artificial intelligence and high - capability computer system and so on . and it can help transfer and identify visible information , enhance the fidelity , imagination and immersion of 3d simulation environment . so it has a broad application future 音頻定位技術作為一門新興的邊緣交叉學科,涉及聽覺心理學、聽覺生理學、人工智能和高性能計算機系統等多個研究領域,且具有廣泛的應用前景,它可以幫助傳遞和識別可視信息,增強三維仿真環境的逼真度、想像力和沉浸感,在軍事和民用方面有廣泛的應用。

An under estimation of the hearing effects by the low frequency noise could be happened . that is to say , even if the a - weight sound level is small , the low frequency noise may annoy to listener by the different ways from the high frequency noise . so it is necessary to understand psychoacoustics in order to make noise quality evaluations that match the subjective experience of the purchaser 同時應用主觀評價方法?成對比較法( paircomparisonstatisticalevaluationmethods )對不同家用空調器噪聲進行主觀評價試驗,并與客觀評價結果進行了對比,結果表明:人主觀響應(煩躁程度)與各心理聲學評價指標之間均具有很高的相關性,相關系數一般均大于0 . 9 ,而與a計權聲壓級之間的相關系數只有0 . 78 。

In the recent years , with the development of such technologies as computer and digital signal processing , transaural technology based on system of kemar grows ; it has a broad future on the domain of electro acoustics , indoor - acoustics , yawp - acoustics , psychoacoustics , computer multimedia and manual virtual environment , which has expanded the scope of the system of kemar 但近年來,由于計算機技術,數字信號處理技術等方面的發展,在假頭型立體聲系統的基礎上,發展了聽覺傳輸技術。它在電聲、室內聲、噪聲、心理聲學、計算機多媒體和人工虛擬環境等許多方面有廣泛的應用前景,其內容已超過了假頭型立體聲這樣一種特殊的聲傳輸和重發系統的范疇。

Then , the method of measuring hrtf by mit and cipic laboratory is briefly reviewed . after that , by using sound wave scatter theory and rigid sphere model of head , a simple method for calculation hrtf is proposed . and validating that method through psychoacoustics experiment , and matching database for realizing individual hrtf 然后簡述了麻省理工學院和cipic實驗室測量hrtf的方法,通過聲波的散射理論以及利用人頭模型提出一種簡化的理論計算對頭部尺寸對聲音定位的影響進行了理論分析,并且利用心理學測試驗證利用匹配數據庫實現hrtf的個性化。

The focus is placed on the investigation of the standard of the encoding algorithm for mpeg audio layer iii , and the analysis of the major four modules in the compression algorithm , including encoding of subband filter bank , psychoacoustics model , quantification and huffman coding , frame packing 重點研究了mpeg音頻第層編碼的算法標準。詳細分析了壓縮算法中的四個主要功能模塊:子帶濾波器組編碼,心理聲學模型,比特流量化與霍夫曼編碼,幀數據流格式化。
