声学

Since I have taken charge of with Beijing, Shanghai, Guangzhou and so on domestic famous acoustics scientific research institution cooperation.

一直以来我司同北京、上海、广州等国内著名的声学科研机构合作。

The obvious sonic benefits to this asymmetrical coverage are that, when properly used, PS systems significantly reduce the amount of ambient, reverberant energy caused when loudspeakers misdirect their output towards walls and ceilings.

这种非对称覆盖在声学上的优点为：使用正确的话，可大幅减小了环境性的反射

But in fact each function has its own acoustical requirements,especially.with their reverberation time,which can notgive same considerations to all functions.

而不同的功能都有各自的声学要求。其中特别是混响时间的差别甚大。难以兼顾各功能的要求。

Associated with the reverberation time of room acoustics.

是与室内声学混响时间。

Sub-band Adaptive Filtering algorithm is a major method to deal with the acoustic echo cancellation problem with long reverberation time.

子带自适应滤波算法是处理长阶声学回声抵消问题的重要方法之一。

A good halls, want to get good sound quality, building on the acoustic design must meet two conditions: IF the right reverberation time and ideals of the reverberation time curve.

一个好的厅堂，想要获得好的音质，建筑声学设计上必须满足两个条件：合适的中频混响时间和理想的混响时间曲线。

Reverberation time is not only an important index in architectural acoustics design, but also an important parameter to appraise gyms' timbre quality.

混响时间是建筑声学设计中一个重要指标，混响时间也是评价一个体育馆音质效果的重要参量。

In complicated acoustic environment where the characteristics of noise field and reverberation time are unknown, the performance of the speech enhancement methods with microphone array face a great challenge.

在复杂的声学环境中，通常噪声场特性和混响强度是未知的，这样就对麦克风阵列语音增强算法的性能提出了较高的要求。

Experimental results validate that our proposed method for calculating the receiving radius can be used to predict some acoustical indexes such as the sound pressure level and the reverberation time in an enclosure.

实验表明，所提出的接收球模型能用来较准确地预测闭空间里的声压级和混响时间等声学参数。

It is revealed that acoustic quality is an important consideration in these buildings, and it may vary considerably with the same objective acoustic indices such as sound pressure level and reverberation time.

分析表明了声品质在这类非声学建筑中的重要性，另外，即使客观指标例如声压级和混响时间相同，声舒适度亦可能完全不同。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
