Efforts to prevent unauthorized access to proprietary, tactical or sensitive information typically focus on securing documents and computers. But measures must also be taken to protect verbal communications from both eavesdropping and electronic espionage.

The LogiSon Acoustic Network can play a crucial role in thwarting audio surveillance attempts in military facilities and those of their contracted suppliers. Additional benefits include reduced noise disruptions, productivity improvements, decreased construction costs, and increased facility flexibility. For more information, see the section on acoustic security.

United States SCIF Requirements

The U.S. federal government has developed several directives intended to protect the security of verbal communications. For example, the Physical Standards for Sensitive Compartmented Information Facilities (SCIF) establishes the construction and security protection requirements for all U.S. government facilities or U.S. government-sponsored contractor facilities in which sensitive compartmented information may be stored, used, discussed and/or processed.

Annex E of this document covers “Acoustical Control and Sound Masking Techniques.” It states that “[w]hen normal construction and baffling measures have been determined to be inadequate…sound masking shall be employed” and may include “vibration and noise generating systems located on the perimeter of the SCIF.”

It is worthwhile to note that installing a sound masking system at the outset can considerably reduce project costs while affording the same measure of protection or greater than traditional methods of acoustical control, such as walls with high STC (Standard Transmission Class) ratings, which are not effective in preventing electronic surveillance.
