1. A system comprising:
one or more microphones configured to detect an audio signal in a local area surrounding the one or more microphones, the audio signal including a plurality of interferences of different interference types, each interference type in the different interference types being a classification of a sound source in the local area that emits a sound of the interference type; and
an audio controller configured to:
for each of the plurality of interferences,
estimate respective energy levels in a plurality of frequency bands; and
apply an interference estimation algorithm to the estimated energy levels to generate an attenuation coefficient for each of the plurality of frequency bands;
for each of the plurality of frequency bands, combining the attenuation coefficients of the plurality of interferences of different interference types to determine a combined attenuation coefficient;
applying the combined attenuation coefficients of the plurality of frequency bands to the audio signal to generate an interference suppressed audio signal in which the plurality of interferences of different interference types is suppressed; and
determine a time domain signal based on the interference-suppressed audio signal to provide to an end user.
