1. An audio device comprising an interface, memory, and a processor, wherein the processor is configured to:
obtain a first microphone input signal and a second microphone input signal;
process the first microphone input signal and the second microphone input signal for provision of an output audio signal;
wherein the processing of the first microphone input signal and the second microphone input signal comprises:
applying a first beamforming to the first microphone input signal and the second microphone input signal for provision of a first beamforming output signal;
determining a first distractor indicator based on one or more features associated with the first microphone input signal and the second microphone input signal;
determining a first distractor attenuation parameter based on the first distractor indicator;
determining a second distractor indicator based on one or more features associated with the first microphone input signal and the second microphone input signal;
determining a second distractor attenuation parameter based on the second distractor indicator;
determining an attenuator gain based on the first distractor attenuation parameter and the second distractor attenuation parameter; and
applying a noise suppression scheme to the first beamforming output signal according to the attenuator gain for provision of the output audio signal; and
output the audio signal via a wireless transceiver for wireless transmission or a connector for wired output of the interface,
wherein the audio device is a headset.
