How to hear through the wall

Wall microphones, also known as walls contact microphones, are professional devices, used for investigation and military purpose. These devices will help to intercept conversations in a confidential and safe way, without any risk of being detected. Letís have a look together to what wall or contact microphones are for and what are their components in order to understand in full all the functionalities of these great investigations devices. There is a huge demand of professional stethoscopes to listen to conversations through the ceiling or the wall of a room.

What are wall or contact microphones for?

A wall microphone is used to intercept sounds by sensors in direct contact with walls or ceilings of thickness up to 70 cm. A contact microphone consists of a microphone capsule, a diaphragm transducing sound vibrations into audio signals, a voice processor and a pre amplifier. An earphone or a digital voice recorder can be connected to the audio output. Our wall microphones are able to detect all noises, including the faintest ones, providing a clear and stable sound. These investigation devices have a very good value for money.

check Professional microphones or wall stethoscopes

State-of-the-art wall microphones. The stereo stethoscope allows you to secretly listen through solid structures like walls, wide roofs, windows, doors and floors. This device is very efficient thanks to two high sensitivity sensors detecting faint vibrations generated by sound waves. The stereo amplifier amplifies the faint sound waves and that can be listened with earphones or live for recording. This is an important advantage.
By using this device, the smallest sound vibrations detected by sensors are amplified (high amplification of bass sounds), so that even faint sounds can be heard.
The automatic selection of the threshold frequencies of amplification levels and microphones, ensures the best fine tuning basing on the operating conditions
