1.【物】亚声的,次声的
1.relating to sound at frequencies below 20 Hz, which cannot be heard by human beings but can be felt as vibration
2.using or produced by infrasonic waves or vibrations
1.The Tunguska event included seismic waves and infrasonic disturbances that were recorded around the world.
通古斯爆炸包含了地震波和次声扰乱，被世界各地记录下来。
2.In this paper, the data processing of hydroacoustic and infrasonic is introduced, and some problem to be related is discussed.
介绍了利用水声、次声进行核监测的数据处理方法及相关问题。
3.The frequencies used in sonar systems vary from infrasonic to ultrasonic.
声纳所使用的频率从次声到超声不等。
4.The infrasonic wave is one kind of frequency is lower than 20 hertz sound waves.
次声波是一种频率低于20赫兹的声波。
5.GIRAFFES communicate with each other at an infrasonic level that humans cannot hear.
长颈鹿用人听不见的低频声音相互沟通。
6.The infrasonic weapon and the traditional arms is different.
次声武器与传统的枪炮不同。
7.Infrasonic is caused by closed automobile compartment or cabin in vibration.
次声产生于关闭的汽车车厢里或在振动的舱里。
8.Therefore some people call it "the silent murderer" , "the mute weapon" the infrasonic wave weapon and so on.
所以又有人把次声波武器称之为“无声杀手”、“哑巴武器”等。
