![]() ![]() When the diaphragm is overloaded with white noise from an audio jammer, other sound waves, such as someone speaking in the same room, are lost in the vibration so it is very hard to pick out voices when listening to the recording. These vibrations move a magnet near a coil of wire which converts the wave energy of the sounds into changes in a small electrical current. There is a small diaphragm in every listening device which vibrates when sound waves hit it. It’s not immediately obvious to most people why this would stop a listening device from working until you take a look at how a microphone works. This means that it contains all the most bassy sounds we can hear to all of the highest pitched sounds we can hear and everything in between, at once, at whatever volume you choose. White noise is a sound that contains all the audible audio frequencies played at the same time and at the same amplitude. Some people think of white noise as static on a radio or old TV and this is nearly correct. The way these do this is by emitting white noise. When you switch on an audio jammer it masks the sound of a conversation, ruining recordings and impeding live audio surveillance. How Audio Jammers Block Listening DevicesĪudio jammers are small, usually mobile, devices designed to interfere with the way listening devices operate. Read on to find out how these devices work and how to use them. You just use a handy little device called an audio jammer. It is this last option that we will talk about in this article because it requires the least amount of effort to put into action. Transmit another sound to mask the sound.Distort the sound that reaches the device.If this is the case then your best option is to try to block the sound from reaching any listening device that might be nearby. ![]() You might also be in a space where checking for hidden microphones is not practical. You can sweep a room for listening devices as much as you like but there is just no guarantee you will find them all. ![]()
