Listen Through Walls - Surface MicrophoneListen through walls and Record
Surface Microphone
The EAR-2000 (Electro Acoustic Receiver) will listen through walls and virtually any surface with the built-in contact element. Simply place the contact against the surface to be tested (metal, air ducts, plumbing, conduit, windows, etc.). The internal automatic gain control will deliver clear, undistorted sound. Also known as a surface microphone or concrete mike, the EAR-2000 can be connected to any standard tape recorder. The recorder output can also be used with audio spectrum analyzers and other measurement equipment for detailed analysis.
The Ear-2000 Assistive listening device is commonly called a concrete microphone or electro-acoustic receiver. It is packaged by the manufacturer as an experimental bomb detection device because of its capabilities to pickup minute vibrations such as the faint ticking of a bomb. This device is often used by professional plumbers to locate leaky pipes embedded in the concrete foundation of a house. It is also used by counter surveillance and security experts to identify sources of voice leakage in a room.
The Ear-2000 will amplify vibrations (listen to) virtually any solid surface including concrete, glass, steel, etc. with exceptional clarity.
Recommended test: place the Ear-2000 against a window and quietly whisper in the direction of the window. You will be amazed at the clarity and amplification of your own voice picked up from the surface of the window. Also works when the vocal source is on the other side of the glass.
Note: this product is intended for training and test purposes only and should not be used in a surreptitious manner.
