Active Acoustic & Vibroacoustic Protection System

A mains‑powered electronic protection system that masks speech and sensitive audio leakage through acoustic and vibroacoustic interference for secure facilities.

Key Features:
✔️Dual‑channel noise generator supporting independent control of each interference zone
✔️Covers key human voice frequency bands (~90 Hz to 11.2 kHz) for effective speech masking
✔️Supports multiple electrodynamic acoustic transducers per channel for broad surface coverage
✔️Passive electromagnetic vibroacoustic transducers transmit masking vibrations through structures
✔️Adjustable emission levels and channel‑specific short‑circuit protection
✔️Compact, 3 kg central unit suitable for command centres and secure installations
✔️Flexible transducer sizes enable deployment on walls, floors, ducts, and piping
✔️User interface with LCD panel for timing, level control, and operational status

Active Acoustic & Vibroacoustic Protection System

The Active Acoustic & Vibroacoustic Protection System comprises a central noise generator unit weighing approximately 3 kilograms that operates on 220-volt mains power. The device supports up to two independently driven channels, each capable of powering multiple electrodynamic acoustic and passive electromagnetic vibroacoustic transducers simultaneously. Acoustic transducers measure 100 by 70 by 35 millimeters while vibro-transducers are compact at 40 by 35 millimeters for discreet installation. The generator covers a frequency range from 90 hertz to 11.2 kilohertz, encompassing human voice bands to mask conversational audio effectively.

The user interface includes an LCD panel displaying operational status and controls for adjustable emission levels across each channel. Short-circuit protection mechanisms safeguard each channel independently to prevent system failure during continuous operation. Operators configure timing schedules for noise generation through the control panel without requiring external programming devices. Transducers attach to walls, floors, ventilation ducts, pipes, and structural voids where sound waves or vibrations could carry speech to listening devices.

Intelligence agencies install the Active Acoustic & Vibroacoustic Protection System in secure communication facilities where classified discussions require protection from external surveillance equipment. Military command centers deploy these systems in briefing rooms where operational planning sessions contain sensitive information. Diplomatic missions use them in embassy conference rooms where hostile intelligence services attempt technical penetration through building structures.

Tactical Supply Pakistan supplies professional counter-surveillance equipment designed to defend against sophisticated technical intelligence collection methods employed by state and non-state actors. Our catalog includes devices that provide measurable protection in environments where information security determines operational success.

Can the system operate continuously without overheating?
Yes, thermal management features allow 24/7 operation without component degradation, making it suitable for permanent installations requiring constant acoustic protection in high-security facilities.
