VOICE RECORDER JAMMER Model No.:JAM07/V generates white acoustic noise in the speech frequency range of 250-4500 Hertz. Sound interference is put onto the recording and makes its quality worse. Due to a uniform distribution of white noise along the whole sound range, clearance of the obtained recording is impossible. The unit should be placed near the designated person to be protected. A digital-analog synthesizer is used to produce the noise.
