A new method measuring speed of sound in a weak scattering fluid is proposed by using the ultrasound - modulated light.
本文介绍一种利用超声调制光波现象测量超声波在弱散射液中传输速度的方法。
The sound signal is Doppler FM modulated based on the analysis of the moving track of the original source, and then phase modulated according to the interaural time difference.
该方法通过对原始声源运动轨迹的分析，对声源信号进行多普勒调频，并根据耳间时间差对双耳信号进行调相。
"Inside, the sound is modulated, so that it is like you are right inside the glass," Parr says.
帕尔说表示：“在里面讲话，音调会变化，仿佛是从玻璃瓶里发出的。”
