Acoustic white noise generator AG8 ensures protection against eavesdropping by using a mobile phone. An alternative to this device — turning the mobile phone off.
What is it used for: during important meetings the participants put their mobile phones into this acoustic white noise generator to protect their privacy without leaving their phones unattended.
How to use this device: in the room (at home or office), the mobile phone is placed in the acoustic generator. The generator does not affect the normal operation of the phone — the phone is within range, it is possible to answer a call, receive text messages, or call immediately after removal from the generator. When you place the phone into the generator, turn on the device. Operation of the device is indicated by a flashing green LED indicator.
Generator’s operating principle: the device generates a white noise sound to a mobile phone’s microphone. The main feature of “White Noise” — an equal noise level in the entire audio section, so this noise cannot be filtered. The noise is generated in a short distance from the microphone, so it affects mobile phone’s sound amplifying circuit — microphone’s sensitivity is reduced. The effect of these two factors is as follows: due to reduced microphone sensitivity, the mobile phone cannot broadcast or record conversations taking place in the room. Instead of the speech audible hissing sounds are heard, which cannot be removed using audio filtering equipment.
Power supply: internal Li-Ion battery. Battery life — about 10 hours. Charging time — about 4 hours. (Battery can be charged while the device is used as it does not affect the performance of the device).
Indication: Red LED (charging indicator) — On: battery is charging; Off: battery is charged; green LED (operating indicator) — blinking: the device is switched on; off: the device is turned off or the battery is discharged.
Packing list: AG8, brief instructions, mains charger.
