Acoustic generator "ARB-GA-Fakir"
Acoustic generator "ARB-GA-Fakir" is designated for the creation of interference to dictaphones, radiomicrophones and other unauthorized devices for voice information retrieval.
In order to assure confidentiality of the in-house negotiations generator of voice-like interference "FAKIR" forms the voice-like interference of complex spectrum, which neutralize the operation of acoustic information retrieval devices or considerably disrupts its normal operation.
• Applied algorithm for generating "voice-like signal" interference with signal fragments selected as per pseudo-random sequence excludes the possibility of information recovery by modern sound cleaning and processing devices.
• Comparing to "white" noise the voice-like acoustic interference enables to mask voice information at noise levels that are lower at 8 – 10 dB.
• Small size and autonomous power supply of the item allow using it in office and automobile.
• When it is necessary to protect voice information in spacious rooms the item can be connected with active external acoustic systems.
