sound level signal

While using detune method can minimize the global sound pressure level with the expense of signal collection and feedback control.

解调策略的优点是能将全局声学指标降到最低，但在实际应用中噪声信号的采集和反馈控制代价过高。

Secondly, experiments were made to analyze the effect of the wheel damper, we used the system composed of a self-made pendulum, three acceleration sensors, a four-channel charge amplifier, a sound level meter, a signal collection analyzer and the DASP software.

其次，对车轮阻尼器的降噪效果进行实验分析。实验采用激振单摆、加速度传感器、电荷放大器、声级计、智能信号采集处理分析仪以及DASP软件组成的测试系统。

Therefore the experiments provide an example to validate the hypothesis that the binaural masking effect is the result of the high level auditory system processing binaural sound signal, and it also hints that by using stereophonic, reproduction speech intelligibility can be improved in communication systems.

因此文中的实验为双耳掩蔽是听觉系统的高层对双耳信号处理这假设提供了例证，并提示通信系统采用立体声作可提高重发语言清晰度。
