Do audio jammers really work?

Audio jammers serve a purpose similar to that of GPS jammers but through different means. They are small devices that produce unique sounds to protect confidential conversations from external listening devices. The random masking sound desensitizes microphones in the area, essentially rendering them useless.

How do you disrupt a voice recording?

How to Block Recording Devices

  1. Purchase a white noise generator. These are small portable machines that create background noise, which makes it difficult for would-be eavesdroppers to hear anything.
  2. Create a safe perimeter for speaking.
  3. Mount the device onto a wall or other smooth surface like a window.
  4. Test the area.

Can microphones be jammed?

While these ultrasonic signals are imperceptible to human ears, they leak into the audible spectrum after being captured by the microphones, producing a jamming signal inside the microphone circuit that jams (disrupts) voice recordings. The leakage is caused by an inherent, nonlinear property of microphone’s hardware.

What is an audio scrambler?

  2. Place the audio jammer in the room where you suspect a listening device may be present.
  3. Test your audio jammer’s effectiveness.
