声学的

Take a look at some relevant dynamic ranges that we have to work with in audio: the range of our hearing, the range of a "good" acoustic environment and the range of a "good" analog audio signal prior to recording.

检查一下我们工作中不得不遇到的一些与音频相关的动态范围：听力的范围，"好"声学环境的范围，和录音前"好"模拟音频信号的范围。

The relationship between the Q value of ultrasonic resonant cavity and attenuation coefficient is educed for the first time,which supplies theoretic support to get the coefficient accurately by interferometry,and a practical method is introduced.

通过测量介质的声学特征量得到介质的某些理化常数的技术称为声探测技术。如测量液体的密度、浓度、粘度、流量、液位以及固体的致密度、晶粒度或球化率、弹性、硬度、厚度

With the down home sounds of the fiddle, whistle, acoustic guitar, mandolin, bass, percussion and keyboards backing up Coulter on piano, each composition shines with a traditional flair sure to strike a chord with listeners.

在背景音乐中，小提琴、口哨、声学吉他、曼陀铃、贝司、打击乐器和键盘乐器等淳朴热情的旋律均成为了 Coulter 钢琴独奏的陪衬，每首作品都闪耀着传统曲风的光芒，打动着听众的心弦。

Line 36 intersects only one corresponding point of all the acoustic drivers of the line array.

与图2中的传统的线性阵列相比，线36仅与线性阵列的所有声学驱动器的一个对应点相交。

In line with the purpose of managing the international first-class musical education, the Electro-Acoustic Music Center of Shanghai Conservatory of Music takes references to the research systems of the Conservatoire National Supérieur de Musique de Paris and the Institut National de l'Audiovisuel, Groupe de Recherches Musicales and other institutions.

本着办国际一流音乐教育的宗旨，上海音乐学院电子音乐声学中心参照法国巴黎国立高等音乐学院，法国国家电台音频研究所等同类机构的研究体系，配备了处于当下世界前沿水平的最先进的硬件、软件和相关设施。

In order to study local scouring field near the pier with sediment control dam ,the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.

According to the acoustic model of piston slap noise, how the parameters affect the piston slap noise at different rotate speed was discussed. And those parameters were piston clearance, piston pin offset, connect rod ratio, piston skirt stiffness, crank shaft offset, height of piston's gravity center, total length of piston skirt, vertical position of piston-pin axis and under part length of piston skirt.

借助建立的活塞拍击噪声理论声学模型，深入探讨了配缸间隙、活塞销偏移量、连杆比、活塞裙部刚度、曲轴轴线偏移量、活塞质心高度、活塞裙部总长度、活塞销轴线竖直方向位置和活塞裙部下段长度等主要影响参数在不同的转速下对活塞拍击噪声的影响规律，初步总结出活塞低拍击噪声设计和改进的基本规律。

The result? Smiles all round from the owners - well, they're still not too happy with the looming presence of the elevated speakers, but we'll sort that some time - and at last some imaging and sense of reality. Enough to work on when they try biwire cables in place of the single-wire stuff they're using.

后来我们用一些东西将音箱向上垫高了20cm，这样使比较低的高音单元发出的声音被沙发很好的吸收，然后我们用毛巾掩住了壁炉口直到后来我们用声学泡沫进行了替换达到了较好效果，并且我们也在音箱上安装了防止震动的脚钉。

This paper presents the method of designing a acoustic sensor monitoring the shock wave and sound wave along with plasma produced in the process of interaction between short-pulse laser and teeth .

介绍了用于激光和牙齿作用后产生的等离子体监控的声学传感器的设计方法，可用于对激光作用过程的监控。
