声学的

Combination of room acoustics characteristics of the different sub-band FIR filter length filtering, limited resources in a more rational distribution, saving resources and computation, and to some extent improve the convergence rate.

结合房间声学的特点，对各子带采用不同长度的FIR 滤波器进行滤波，将有限的资源进行更合理的分配，节省了资源和计算量，并在一定程度上提高了收敛速度。

Then the developments of the thermoacoustic machine are reviewed. The thermoacoustic theory is introduced from different points of view. Two typical style of thermoacoustic engine are discussed, followed by thermodynamic circle, principal equations, fluid network principle and oscillation theory.

本文简要回顾了热声学的历史和研究现状，并从几个不同的角度对热声机械的基本原理进行了简要介绍，接着对二种典型形式的热声发动机装置进行了介绍，然后介绍了热声热机的热力循环、基本方程以及流体网络理论和振动理论。

In auditory psychophysics, dramatic developments over the last few years have changed our understanding of temporal pitch mechanisms, and of the roles of resolved and unresolved harmonics.

在听觉的精神物理学方面，戏剧性的发展前几年已经改变我们的理解暂时的球场机制以及决心和不坚决的和声学的作用。

We determined the basic mechanical and acoustic behaviors of reconstructed cartilage plate compared to the tympanic membrane.

相较於耳膜，我们找出了用於重建的软骨板基本的动力学及声学的行篇模式。

From an acoustics point of view, the 0.2 to 0.5 mm cartilage plate depending on different areas of perforation seems to be most preferable with regard to tympanic membrane vibration.

由声学的观点而言，0.2至0.5公厘的软骨板於不同面积大小的破洞重建中，提供了较佳的耳膜振动。

Results of psychoacoustic experiment also show that the HRTF without pinnae has almost the same localization effect as the HRTF with pinnae, while has less change in timbre.

心理声学的实验结果表明，新处理方法的声像定位与传统的带耳壳、耳道的HRTF处理无显著区别，但音色较后者有所改善。

Neuroacoustic research has shown that brainwaves tend to resonate with our sound environment.

神经声学的研究显示，脑波会与环境中的声音产生共振。

Inunderwater acoustic research specially in shallow-sea acoustic,the scatteringon different rough surface is important factor affecting underwater environmentand background.

粗糙表面声散射在很多领域均有重要的应用，水声研究中尤其是浅海声学的研究，各种粗糙界面的散射更是影响水下环境和背景的重要因素。

In this thesis, a mathematical model of multi-path channel is established by using the theory of ray acoustic to simplify the physical of underwater sound channel.

本文利用射线声学的方法，简化了水下声信道的物理问题，构造出一种多途信道的数学模型。

I can definitely tell you that Constellation is in a class by itself in electroacoustics," he says."The latitude it offers for digitally managing a listening experience goes significantly beyond the other systems I've heard.

我可以确定地告诉你，Constellation系统在电子声学的领域目前还没有其他的系统能够做到，&他说：&这个系统为听觉体验提供的数字化控制能力远远超过我所听过的其他系统。
