The hydrophone records from the deep waters where they spend most of their time revealed them to be much more common.

水听器深水区的记录则表明，在深水区，抹香鲸确实更为常见——他们本就习惯在那儿呆着。

For the first time, scientists have been able to observe these deep-sea eruptions through high-definition video and audio, thanks to a hydrophone that was later matched to the video footage.

这是第一次，科学家们能够观察到通过高清晰度视频和音频这些深海火山喷发，到后来的录像相匹配的水听器的感谢。

Based on the deep study of displaced phase center algorithm, an improved movement error estimation algorithm for multi-hydrophone SAS was proposed.

在深入分析位移相位中心算法的基础上，提出了一种改进的多接收元合成孔径声纳运动补偿算法。
