| Partition listens detector is the use of airborne sound effect of the wall in the room, the air acoustic signal generated by the vibrations of sound waves, was listening in the next room, through two high-sensitivity sensors close to the wall or fixed on the body, picking through the wall of the weak propagation acoustic signals. Filtering the electrical signal picked up, and the amplification and digital signal processing to restore the speech signal, storage, playback, etc., to obtain information or information purposes.
隔墻偵聽探測儀主要是利用聲音經空氣傳播作用於房間的墻體, 由聲波的振動產生空氣聲信號，在被偵聽的隔壁房間裏，通過兩個高靈敏度傳感器緊貼或固定在墻體上，拾取經過墻體的傳播的微弱聲波信號。將拾取的電信號進行濾波、放大以及數字信號處理並將語音信號進行還原、存儲、回放等，達到獲取情報或者信息的目的。 |
