振听是日本麻将中一个重要的概念：振听有以下三种情况
振动听诊 vibratory auscultation
振速水听器 [声] velocity hydrophone
听唤振铃键 listening and ringing key
振动听骨链重建假体 VORP ; vibrant ossicular reconstructive prothesis
听话振铃合用键 combined line & ringing key
引起听觉的振动波兵器 sonic weapon
又名振动人工听小骨 vibrating ossicular replacement prosthesis
引起听觉的振动波测井 sonic logging
压差水听器是水声矢量水听器的一种实现形式，同振球则是另一种实现形式。
Pressure gradient hydrophone is one of the implementation forms of acoustic vector sensors while another form is the vibrating sphere.
了付好耳机，你需要个耳放因他能比糟糕的声卡或者随身听驱动耳机振膜更好。
With decent headphones, you need an amp because it can drive the diaphragms of the headphones much better than a crappy sound card (or CD player).
矢量水听器由于能获取声场中标量(声压)和矢量(振速)信息，因此单个的矢量水听器就可实现目标方位估计。
An acoustic vector hydrophone measures the scalar acoustic pressure and the vector acoustic particle velocity, thus the DOA can be estimated by single vector hydrophone.
