How to Block Listening Devices
Listening devices are used to eavesdrop on conversations remotely. Usually small and easy to hide, listening devices are used by law enforcement as well as private individuals. This article talks about how to block listening devices.
One key feature of smart homes is that all the connected smart devices are usually from the same manufacturer. For example, if you own a doorbell made by Apple, your cameras, thermostats, sensors, and sprinklers will probably be made by apple or affiliate companies.
However, once all those devices are somehow connected to the same network, all a hacker need is to have access to one device, then he/she can find a back door into all your devices. This can be used to spy or put you on surveillance. For example, to listen to your conversations, all that person must do is find a way into a device that has a camera or microphone. For example, a Smart Tv is just a TV to you, but it is a node on a network to the hacker. To gain access to the TV, the hacker may use a modified infrared transceiver connected to a computer to send commands to the TV. They may also use Bluetooth.
However, blocking a listening device is usually a matter of either distorting the sound input received by the device, sending another sound to mask it, or blocking the sound outright. Typically, sound jammers are used to neutralize nearby microphones.

- Purchase an audio jammer. Audio jammer devices are expensive, but you can rely on them to desensitize any hidden microphones within a given diameter. This device is small and discreet, and it can be easily hidden.
- Place the audio jammer in the room where you suspect a listening device may be present. However, the sound jammer will generate a random masking sound.
- Test your audio jammer’s effectiveness by using your own listening device in a room in which an audio jammer is present and listen to the recorded results to see if you understand them. However, the sound jammers have been proven effective against tape recorders, hard-wired microphones, RF transmitters, and shotgun microphones.
