A noise cancelling headset includes first and second earpieces, each earpiece including a respective feedback microphone, a respective feed-forward microphone, and a respective output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

An ear tip to audio headset connection system. The invention support both open ear fit, and closed ear fit ear tips, and distinguishes which is currently attached. Open ear and closed ear configurations normally generate differing audio signal characteristics. Including differing levels of overall volume, as well as different amounts of attenuation across the audio spectrum. Our invention adjusts the audio signal limiter, equalizer and other audio settings differently for each type of earpiece, compensating for their inherent differences.

A headset includes an acoustic structure, a first microphone located outside the acoustic structure, a second microphone located inside the acoustic structure, and an output driver configured to receive an antinoise signal based on a combination of input from the first and second microphones. A voice signal of a user of the headset is generated using input from the first and second microphones. The first microphone could be a feed-forward microphone that provides input to a feed-forward filter to produce a filtered feed-forward signal for producing the antinoise signal. The second microphone could be a feedback microphone that provides input to a feedback filter to produce a filtered feedback signal for producing the antinoise signal.

A signal processor (105) for a headset (101) configured with a microphone terminal (106) for receiving a microphone signal, a loudspeaker terminal (107) for outputting a loudspeaker signal, and a far-end terminal (108) for communicating an inbound signal and an outbound signal with a far-end; comprising: a side-tone path (110) configured to generate a side-tone signal from the microphone signal via a controllable side-tone filter; wherein a side-tone filter controller (114) receives the microphone signal and computes a first noise estimate with a signal-to-noise level of the microphone signal at respective frequency bands and based thereon controls the side-tone filter (111) to improve or optimize a signal-to-noise ratio.
