About this file
This document is a product specification sheet for the AMC A20 Sound Transmission Class (STC) Testing Kit, a portable system designed for acoustical compliance testing of Sensitive Compartmented Information Facilities (SCIFs).
The kit is engineered to meet ICD 705 standards for STC ratings, supporting Sound Group 3 (STC 45 or better) and Sound Group 4 (STC 50 or better) classifications. The system is a complete, turnkey solution intended for single-operator field deployments, temporary duty assignments, and Program Compliance Reviews/Inspections, with all components packaged in ruggedized travel cases weighing less than 50 pounds each. Key included components are an integrated speaker and noise generator, sound level meter with periodic NIST calibration capability, precision calibrator (94/144 dB), tripods, PointSource Field STC Software (with no subscription fee), laptop with power supply, high-grade hearing protection, and extension cord. The software provides guided testing using precise distance measurements and SPL amplitude readings, automatically calculates both STC and Noise Transmission Class (NIC) values, generates formatted compliance charts and graphs for accreditors, and includes integrated report-building capabilities. The system enables evaluation of doors, walls, or rooms within minutes and supports remote measurement capability. All test results are instrumented to support SCIF accreditation requirements.

AMC A20 Sound Transmission Class (STC) Testing Kit
• Shall meet the ICD 705 standards for the STC ratings o Sound Group 3 - STC 45 or better. Loud speech from within the SCIF can be faintly heard but not understood outside of the SCIF. Normal speech is unintelligible with the unaided human ear.
o Sound Group 4 - STC 50 or better. Very loud sounds within the SCIF, such as loud singing, brass music, or a radio at full volume, can be heard with the human ear faintly or not at all outside of the SCIF.
• Primary use for Sensitive Compartmented Information Facilities (SCIFs)
• Designed for single operator field deployments, TDY’s, Program Compliance
Reviews (PCR’s)/Inspections
• 100% turnkey (includes speaker, generator, tripods, cases), no putting together the system with multiple parts
• PointSource Field STC Software included, manually process raw noise measurements, quick test mode, multi-point 3D room testing, communication directly and controls the SLM, steps the operator through the precise distance measurements, and automatically calculates both Sound Transmission Class (STC) and Noise Isolation Class (NIC) values, include an integrated report builder to immediately generate, save and print formatted compliance charts and graphs for accreditors.
