Anti-eavesdropping noise generator MNG-06

GENERATOR WITH 4 OPERATING MODES The noise generator is distinguished by the four operating modes provided. Each of them is heard by those present in the room and can be adjusted as a volume level with levels from 1 to 7. This is done as functionally as possible with the help of just one button that can be pressed and turned. The first operating mode is the generation of white noise. Here, two types of white noise are provided, each of which is subject to volume level adjustment from 1 to 7. Their purpose is to block microphones and ensure the confidentiality of conversations. The two types of white noise cover all frequencies of the human voice. The second mode resembles tens of thousands of people speaking simultaneously. Here again, two types of speech-like noise are provided, the purpose of which is to neutralize eavesdroppers and assess the permeability of sound through various barriers and protections. The third option for the generator is to play a sharp rhythmic sound with different octaves. Again, two types of noise are available, also called a metronome. With their help, microphones are activated that respond to sound and the sound permeability through barriers and protections is also assessed. The last, fourth mode is a rhythmic sound with different frequencies. This mode is also called octave, and its characteristic is that it creates sounds in a very wide frequency spectrum. Its purpose is again to activate VOX eavesdroppers and to analyze the sound permeability. The device can be powered in several ways. The first is with the presence of a 9V battery, which can be rechargeable or disposable, replaceable. In this case, with one full charge you will work for at least 4 hours at maximum noise power and about 8 hours at minimum power level 1. If you use a rechargeable 9-volt battery, then there is an option to connect the tool to an external 12-volt power supply. With the device turned off, you will recharge the battery, which will take about 16 hours. With the generator turned on, you will be able to work with it without any time limit.
