1 the companies here mostly make high performance audio devices . these products are designed to produce excellent sound quality when you listen to music and movies 这里的参展公司的公司大部分是展示高品质的音频设备。这些产品设计出来是用于当你在听音乐或看电影时表现出卓越音质的。
An a d conversion in " cd quality , " i . e . using 16 - bit dynamics , leads to a resolution of approx . 65 , 000 values . however , if the conversion is done in 4g , i . e . using 24 - bit dynamics , the computer is fed an impressive 16 million possible gradations 当模拟音源被转换为等同于cd音质的数字信号时，也就是3g声卡使用的16bit ，能将之分割成为65 , 000组数据到了现在的4g的24bit技术，更能提供电脑高达1600万组的数据。
Realaudio is used to transmit audio data with the quality of cd ; realvideo is used to transmit continuous video data ; and realflash is a format of motion picture with a high compression ratio recently developed jointly by realnetworks and macromedia Realaudio用来传输接近cd音质的音频数据， realvideo用来传输连续视频数据，而realflash则是realnetworks公司与macromedia公司新近合作推出的一种高压缩比的动画格式。
4g : by the end of the noise - filled century , a new converter technology begins to emerge as a trend in studio music production : " 24 96 " makes its entrance in professional studios all over the world and new devices with high sound quality are being developed 二十世纪末起，在家中以个人电脑创造出媲美专业录音室等级音乐，成了最新的流行趋势。而一般专业录音器材对音质的要求最起码都要在" 24 - bit , 96 khz " 24 96以上。
I block absorption of office space in accordance with the noise developed new products , technology leading to meet noise control , the need to improve quality , eliminate indoor noise pollution , promote health , improve work efficiency , and will play a significant positive effect 吸声隔断是我公司根据办公空间的噪声研制开发的新产品,技术水平领先,可以满足控制噪声,改善音质的需要,对消除室内噪声污染,促进身心健康,提高工作效率,将起到明显良好的效果。
Analysis the sound quality effect by the frequency response of speakers . and put forward compensate the frequency response of speakers using equalizer . compressor , expander , limiter and noise gate are important for the audio system , this paper also introduce them , and describe how to use them 然后简单介绍了音频系统和组成，叙述了扬声器的频率响应特性及其对音质的影响，提出使用均衡器补偿扬声器频响特性的方法；动态范围压缩器、扩展器、限制器在音频系统中也起着重要的作用，本文也对其做出了介绍，并阐述了它们的用途和使用方法。
This thesis begins with the general principle of indoor acoustics and researches on the rule of the acoustics wave spreading ; analyzing mainly the features that the acoustics wave reflex on the concave 。 secondly , this thesis analyzes and summaries the evaluation index of indoor sound quality , knowing the relation between the subjective evaluation and the objective physical quantity 。 absorbing the experience the predecessors have got on the indoor acoustics design , master the general principle and methods of indoor acoustics design 本文首先从室内声学的一般原理入手,研究声波传播规律,重点分析声波在凹面上的反射特点。其次对室内音质的评价指标进行分析和总结,了解室内音质的主观评价与客观物理量之间的关系。吸取前人在室内声学设计方面的经验,掌握室内声学设计的一般原则和方法。
With regard to some specific problems encountered in the process , the pointed answers are given by way of simulative experiments in laboratory . those problems are as follows : the relation between rt curve and rasti , different impacts caused by different acoustic characteristics on different standing waves , the changes of acoustic quality derived from different positions of sound absorption materials 而对此过程中遇到的某些特定问题，如：混响时间频率特性与清晰度的关系，不同声学特性对驻波的影响，吸声材料摆放位置不同带来的音质的变化等，则以在实验室模拟实验的研究方式予以针对性的回答。
Under the direction of the sciences of auditorium acoustics , the paper researches on the auditorium acoustics of the digital conference hall . on the basis of analysising the theory background , the paper researches on the practical construction project . the basic task of is to study the physical conditions of interior acoustic wave transmission and acoustic processing method approach to ensure a good indoor heard 本文以厅堂音质的相关理论为指导,以数字会议厅堂为主要研究目标,以会议厅堂音质设计为主要研究内容,在总结了会议厅声学设计中各个基本概念及厅堂音质设计的基础上,对现代数字会议厅堂的音质展开深入的研究,并理论结合实际,对具体的工程项目进行厅堂音质设计与研究。
The value of this article is that , through research to the national conditions , some suggestions have been proposed in details to guarantee the high quality of acoustics of living room in residence design as primary principles and methods for architects and designers of residence decoration 因此对我国起居室音质的研究就显得格外迫切。本文选题的意义就在于：针对国情进行研究，提出具体的建议。为建筑师、装饰工程设计者提出保证住宅设计中起居室高质量音质的基本原则与方法。
