Keep your private conversations private! The AJ-34 AUDIO JAMMER protects your sensitive room conversations by generating a random (white noise) masking sound which desensitizes any near-by microphone or tape recorder. Effective against any microphone based eavesdropping device including tape recorders, RF transmitters, hard-wired microphones (including contact type) and shotgun microphones. It also protects against microwave or laser reflection pickups. Because the sound from the jammer varies randomly in frequency and amplitude, it cannot be filtered and the only sound the eavesdroppers will hear is the jammer noise. The convenient end-mounted control lets you select the level of protection for your situation. One unit will protect up to 150 sq. ft. For protecting rooms larger than this, we recommend an additional jammer for each 150 sq. ft. of area. The illustrated instructions show suggested jammer placement for different types of rooms and situations so that you can use the AJ-34 effectively. The AJ-34 is powered by one 9 volt alkaline battery (included). The unit measures 4 x 1.5 inches and weighs 7 oz.

This sounder makes a noise that kills the microphone. Really amazing. But not silent.
So the thing to know is that it makes a noise. Sounds like you turned to a tv or radio channel that does not exist. Static sounding noise. But that is the magical thing that causes the microphones to be useless in that environment. It somehow makes the microphone not work right. So hidden recorders and bugs are useless. Battery powered makes it very portable in hotels, car, etc. My business dealings stay my business.
