The anti-recorder talk jammer is only effective for mobile phones and other digital products, and does not interfere with people. Because the human body does not receive ultrasonic waves, the mobile phone records all noise, but people cannot hear it, so speak jammer does not affect normal conversation and communication, and it does not even detect the protection. The recorder is working.
