Audio Jammer Sound and Ultrasonic Jamming

The sound produced by an audio jammer depends on the technology used. Our ultrasonic audio recording blockers utilize high-frequency sound waves—waves with frequencies that may lie beyond the range of normal human hearing. This difference can matter when considering an anti listening device for meetings, offices, interviews, or private conversations.

Anti-recording blocker sound can also affect how recording devices capture speech. Ultrasonic jamming aims to disrupt a microphone's ability to capture clear speech signals, thereby rendering the recorded speech difficult to decipher.

Important things

1.Please install the antenna before using the signal jammers

2.Most Portable cell phone jammers have dip switches on the side. After turning on the main power switch, activate the dip switch—the red or green light will indicate it's on. Each switch controls a specific signal (Refer to the frequency table on the packaging for details).
