1. A device comprising:
a microphone;
a sidetone filter configured to:
receive an audio signal from the microphone, the audio signal comprising ambient noise and a voice of a user of the device; and
filter at least a portion of the ambient noise from the audio signal to generate a sidetone signal; and
a processor configured to:
process the audio signal from the microphone received by the sidetone filter including determining a level of the ambient noise in the audio signal from the microphone received by the sidetone filter;
control a frequency band of the sidetone filter based on the ambient noise in the audio signal; and
dynamically adjust a gain applied to the sidetone signal based on the level of the ambient noise.
