Voice Masking Generator
Voice Masking Generator
The Voice Masking Generator 2 (VMG2) is a compact, portable, and programmable voice masking device designed to help protect private conversations from eavesdropping.
Single-Point Acoustic Security for Sensitive Conversations
The newly redesigned VMG-2 is a portable, direct-field, multi- layered speech generator designed to enhance speech privacy in fixed or mobile locations. The unit is designed for single-point, “at the perimeter” acoustical security for sensitive conversations spoken inside a room. Built for a variety of applications, the VMG-2 is perfect for addressing single-point vulnerabilities associated with flanking path vulnerabilities often found in hotel rooms, typical office spaces, and similar locations not otherwise designed to protect speech.
Protect Flanking Paths
Conversations can easily escape though holes in the walls, gaps beneath or around the doors, through vents, and even through gaps in the electrical outlets and ductwork, commonly referred to as “flanking paths.” Doors are typically the number one problem regarding acoustic security in an office. These flanking paths are the major contributor to reduced STC performance. Doors, walls, and penetrations (e.g., ventilation ducts) with poor acoustic attenuation properties allow others outside of the room to hear sensitive discussions being held inside the room.
Convenient
The new VMG-2 is a self-contained, battery-powered unit that can operate for up to 24 hours on a single charge using the internal rechargeable lithium-ion battery or can be permanently powered by using the supplied 5 V dc power supply. Simply turn on unit and place it against a wall or door. Audio generated through the speaker vibrates the structure, making it very difficult to discern between the conversation and the generated voice mask from outside the room. The VMG-2 can support a variety of external transducers to accommodate voice masking at large gaps, through ducts, etc.
Targets Voice
Unlike other noise generators, the VMG specifically targets voice frequencies and speech characteristics. The VMG-2 contains 32 GB of on-board memory with factory-programmed audio composed of unsecure HVAC/pink noise as well as much more secure audio consisting of multi-layered conversational voice masking. Using a proprietary approach to voice masking, Transformational Security layers multiple innocuous conversational audio sources containing a full spectrum of voice frequencies. When the sensitive conversation mixes with the voice mask, it becomes indecipherable.
