How do Audio Jammers and Noise Generators work?
Audio Jammers and Noise Generators make it extremely difficult for wiretaps to record your most private conversations by masking against hidden listening devices, thereby protecting confidential conversations where sensitive information may be exchanged; an Audio Jammer generates a random masking sound which desensitizes any microphone that is near. This jammer is effective against any microphone-based eavesdropping devices, including tape recorders, RF transmitters, hardwired microphones, and shotgun microphones. Noise Generators have been calibrated for voiceband noise, masking against listening devices and are designed to reduce the effectiveness of eavesdropping devices such as microphones and tape recorders.
