Abstract
Aspects of the subject technology relate to a device including a microphone, a filter and a processor. The filter receives an audio signal including ambient noise and a voice of a user of the device from the microphone. At least a portion of ambient noise is filtered from the audio signal. The processor determines a level of the ambient noise in the received audio signal and dynamically adjusts a gain applied to the filtered audio signal based on the level of the ambient noise.
Claims20
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.

A device comprising:
- a microphone;
- a filter configured to:
- receive an audio signal from the microphone, the audio signal comprising ambient noise and one or more sounds;
- and
- filter at least a portion of the ambient noise from the audio signal with a sidetone filter to generate a filtered signal;
- and
- a processor configured to:
- determine a level of the ambient noise in the audio signal received by the filter;
- dynamically adjust a gain applied to the filtered signal based on the level of the ambient noise;
- and
- dynamically control operational characteristics of the sidetone filter based on the ambient noise.
