PELTOR™ ComTac™ VI NIB Headset, Headband & Arc Single Com MT20H682FB-47N

About NIB Natural Interaction Behavior: NIB is designed to improve near proximity communication in high noise without the need for an external communications radio nor vehicle/boat/aircraft intercom system when in transport. The NIB function allows for 4 team members to transmit simultaneously, and over 60 people to receive, within about 30 feet/10-meter radius of the talker(s). Technically, it can be described as a very low wattage, baseless, connectionless, broadcasting single hop mesh, using Time Division Multiple Access (TDMA) to create several dynamically allocated and reusable virtual communication channels.

Audio transmit is activated by either a voice activated switch (VOX), for hands free operations in high-noise (approximately 80dB SPL and higher), or by a push-to-talk (PTT) button located on the left earcup. On some headset models, the VOX switch is adaptive, meaning the threshold to activate will adjust automatically to the environmental noise. The NIB PTT button also serves as a mode button allowing the user to switch between three NIB settings: NIB Off, NIB VOX On, and NIB PTT On.

The NIB function is easy to use. Team members in proximity of each other (about 30 feet/10 meters) will be automatically connected (when the NIB function is on)
