声波兼有标量场和矢量场，传统的声压水听器系统仅利用了其声压信息。

On the basis of this method , this dissertation makes further analysis on the sound reflection in spherical conformation .

而本文是在这一方法的基础上对球形构造声反射做更进一步的分析，对其形成的声聚焦区域及区域内的声压级的增量得到量化的结果。

To measure, calculate, display, print sound intensity sound pressure, sound power, three dimensional sound intensity spectrum, equal intensity contour are all deeply studied.

本文就声强、声压、三维声强谱、等声强线以及A计权、1/3倍频程的测量、计算、显示、打印等进行了深入的研究，并编制了一整套运行于Windows平台的图形化多文档界面声强测量分析软件。

And then the interference phenomenon of pressure and velocity is discussed, which shows that the pressure and the horizontal velocity have the same interference pattern.

通过对声压、振速的干涉现象进行分析，说明了声压和水平振速符合一致的传播规律。

In the experiments, the accelerometer and the microphone are used respectively to measure the acceleration on the panel and the sound pressure in the cavity. Piezoelectric ceramics Transducer is used as the control source to control reverberant sound field transmission through a simply supported rectangular aluminium panel into a concrete cavity.

实验中采用加速度计和话筒作为传感器拾取板振动的加速度和闭空间内的声压信号，用压电陶瓷片作为振动控制源来控制混响声场通过简支矩形铝板向混凝土闭空间的声传入。

Sound wave has both scalar quantity and vector field, while traditional acoustic pressure sensor system merely makes use of its acoustic pressure information.

声波兼有标量场和矢量场，传统的声压水听器系统仅利用了其声压信息。

The sound pressure fields at M=0, M=0.1 and M=0.2 are also given out. It is found that the constant pressure contours at the distances not too far from the duct end are caved-in backward due to the effect of flow. And it can be explained using Snell's law.

同时还给出了M=0、M=0.1和M=0.2管口辐射声场的声压分布，发现流动使离管口稍远处声压等值线向管口方向凹陷，并用Snell定律作了解释。

However, the continued wavefields in traditional one-way wave equation migration are not the downgoing or upgoing components of the acoustic pressure wavefields. The amplitudes on the migrated sections still disagree with the reflection coefficients even if the dynamic imaging condition is applied.

不过，传统单程波动方程偏移的延拓波场并不是全波场的上、下行声压分量，即使采用常规的动力学成像条件，得到的成像振幅与声压反射系数之间也没有直接联系。

When the Japanese cedar diffusers add in each simulation could lower the SPL level and get the similar data in three different shapes,.

室内空间在配置柳杉材扩散板后，整体而言声压位准明显下降，并且各测点之声压位准差异降低，显示柳杉材扩散板之散射及吸音性能对声场有显著之影响。
