Real Reverberation/Recording/Reproduction Room (R4 Room)

As of 2020, IAR has expanded and added more office space as well as a third test facility. The "room within a room" is an interior office room with standalone ductless HVAC.

This facility supports ETSI 202-396, ETSI 103-224 and ITU-P P.570 and Alexa device testing. Reverberation times are configurable by adding or removing wall panels and carpeting.
