INTRODUCING OUR HANDHELD PERSONAL ULTRASONIC UNIT, MADE IN USA!

 

SUITABLE FOR PORTABLE USE OR FIXED PLACEMENT

 

PLEASE NOTE: THIS DEVICE IS SILENT TO THE HUMAN EAR BUT IT GENERATES A SPECIAL SOUND.

 

Why do you need the Ultrasonic Audio Jammer? If you have conversations in person that require you to discuss sensitive or proprietary information, you may be at risk of a wireless microphone or audio recorder being used to spy on your conversation.

 

Many devices are rendered useless by the “Ultrasonic Audio Jammer”. It is effective against any microphone based eavesdropping device including: tape recorders, RF transmitters, hard-wired microphones and shotgun microphones. It even protects against microwave or laser reflection pickups. Also effective against Alexa, Echo, Siri and other voice-activated devices. Simply point at the device and turn the jammer on. The Ultrasonic Audio Jammer varies its frequency and amplitude randomly, making easy filtration impossible. The only sound an eavesdropper will hear is the Ultrasonic Audio Jammer noise.

 

The convenient handheld size lets you take the device anywhere. One unit will have a protected range of anywhere from 3-4+ meters or more, directly in front of the unit. The protection beam is unidirectional. This may protect the majority of a small room.

 

This module is more effective than the traditional audio jammer units and emits a sound that humans cannot hear but hidden microphones can. It is rechargeable and can run for approx. 1+ hour between charges, ensuring you have privacy when you need it. Conveniently charge from any 5V USB port - no charge adapter needed!

 

Don't be fooled by cheaper, larger units other sellers make from cheap Chinese white noise kits. Our ultrasonic unit is based on our own custom microcontroller to ensure peak effectiveness. It is manufactured in the USA. For peace of mind, choose Silentek.
