Abstract
A communications headset having multiple modes of communication, including DECT7 wideband and narrow band, Bluetooth®, two-way radio connectivity, and USB connectivity. The system includes a DECT7 transceiver, a Bluetooth® transceiver, a microcontroller, and a digital signal processor (DSP), all connected on a bus. The DSP and a portion of the microcontroller can be reprogrammed via signals through the USB port or via signals from the Bluetooth® transceiver. The reprogramming signals originate from a computer that is temporarily linked to the headset via USB cable or Bluetooth®. The system provides listen-through capability, enabling face-to-face conversation while using DECT7 communications. The DECT7 communications have a noise gate that shuts off all noise when there is no voice signal present. The headset provides substantial hearing protection via passive and active noise cancellation and includes a sound pressure dosimeter.
