Study shows that the error is biggish in high frequency range.

针对声场大多呈非线性的特点，提出了应用几何平均计算声压的方法。

However, at this point where Bl has dropped 30% the Qts has also increased to about 1.3 vs the rest value of .7. As a result the sound will change as volume levels are increased and it will become more boomy.

但是，因为BL值下降了30%，Qts也因此升高到大概1.3，这个结果是，当声压提高时低频会更加强烈。

A new direction of arrival estimation method is proposed using a single vector hydrophone, which is composed of three spatially co-located but orthogonally oriented velocity hydrophone plus another co-located pressure hydrophone.

摘要提出了一种基于单个矢量水听器的二维波达方向估计方法，该矢量水听器由三个空间轴向垂直的振速水听器和一个声压水听器构成。

By investigating the differences among the behaviors of sound pressure responses of four types of stiffened plates and an unstiffened one, we obtain a structural design which can effectively modify the stiffness of a plate structure and its sound radiation behavior.

透过四种加劲设计之复合材料结构板及未做加劲设计之平板的比较，探讨其声压曲线之差异以及差异产生的原因，来研究如何做出能有效提高平板结构刚性之加劲设计。

Speakers import modules with a combination of : titanium membrane Treble, and with fiberglass trumpet, better high frequency extension stronger sense of space; Bass modules using imported pulp Senate carbon fiber, rigid speaker cone greatly strengthened, the effective bandwidth within a more flat frequency response and bass modules using aluminum frame and aluminum wire voice coil. Shaker skeleton of the United States military material, light weight, high efficiency, so that the audio sound pressure increased significantly. more males, bass magnetic circuit using high efficiency of the cooling system to ensure that the speakers have very good heat dissipation, reduce distortion, effectively reduce the power to the compression.
