Abstract
An audio headset that provides a 'chat' mode to temporarily adjusts audio to preset levels to emphasize ambient sound, and includes a beamformer to provide directional speech isolation. The headset may include active noise cancellation and/or passive noise isolation. When entering chat mode, three or more relative audio levels are individually adjusted to presets, allowing the wearer to hear ambient noise and their own isolated voice, while attenuating other audio sources. This user-configurable combination of levels temporarily adjust the mix of signals that will be output to a wearer via the stereo headphone speakers.
