The AJ-34 Audio* Jammer protects your sensitive room conversations by generating a random masking sound to desensitize any nearby microphone and ANY device that uses a microphone.

Since the masking sound varies randomly in amplitude and frequency, it cannot be "filtered out", so the eavesdropper will only hear the jammer noise.

*Note: Yes, it is audio. That means you can hear it. While a jammer in the microwave range would not be heard, it would make a person uncomfortable after a while. We don't offer anything in the microwave range.The AJ-34 does work against microwave and infrared listening.

The AJ-34 comes complete with illustrated instructions showing jammer placement for different types of rooms and other areas.
