Defeat the mighty Knowles microphone.

The noise generator is a microphone stopper, and it’s not technical to operate. The speaker outputs sounds similar to a radio that’s not tuned in. However, the sound is not random, and pre- prepared to oscillate at a unique sound frequency. Effectively, destroying the sound harmonics of a typical microphone voice frequency.

White noise can be loud.

You physically hear the sounds coming out of the white noise generator, audio sounds like a hissing noise. The distortion mask’s the sound of your voice,  effectively defeating surveillance microphones, and stopping them from clear recording. The audio jammer is effective at masking your voice conversations, as the sound amplitude is higher then your voice?

Value for money.

The best priced device for disrupting or masking voice audio. The white noise generator works every time, and it will always guarantee results. The laws of physics rarely change and sound waves require air to travel over, thus wright noise must work too.

Ultrasonic sound jammers.

Trusting an ultrasonic wave jammer presents unknowns during operation, is the system truly stopping digital microphones? In tests, we found 50% of digital microphone nullifiers fail to stop digital microphones from recording voice audio. It seems like high tech equipment is not always the best TSCM unless you buy a product that works.

Safety comes first.

Did you know? many ultrasonic sound jammers emit radio frequencies, some of which are not good for your health. Safe to say, radiation is often present when we use a mobile phone. However the amplitude is monitored and regulated, offering diligence associated to use.

Some ultrasonic jammers & cell phone jammers breach recommended safety limits. Often emission levels are not highlighted, we recommend you check radio frequency outputs before you purchase expensive ultrasonic equipment. The wright noise generator is totally safe and it only outputs sound, no radio frequencies.
