Ear-worn electronic device employing user-initiated acoustic environment adaptation
An ear-worn electronic device comprises a microphone configured to sense sound in an acoustic environment, an acoustic transducer, and a non-volatile memory configured to store a plurality of parameter value sets, each of the parameter value sets associated with a different acoustic environment. A control input is configured to receive a control input signal produced by at least one of a user-actuatable control of the ear-worn electronic device and an external electronic device communicatively coupled to the ear-worn electronic device in response to a user action. A processor is configured to classify the acoustic environment using the sensed sound and determine a listening intent preference of the user. The processor is configured to apply, in response to the control input signal, one of the parameter value sets appropriate for the classification and the listening intent preference of the user.
1. A method implemented by an ear-worn electronic device configured to be worn in, on or about an ear of a user, the method comprising:
receiving an adaptation request in response to a user action;
capturing a sample of ambient sound in response to the adaptation request;
receiving a listening intent preference of the user;
determining a set of audio processing parameters based on the ambient sound and the listening intent preference; and
applying the set of audio processing parameters to a captured audio stream to deliver processed sound through the device, the processed sound being consistent with the listening intent preference of the user.
2. The method of claim 1 , wherein receiving the listening intent preference comprises receiving a preference between two or more listening intent preferences.
3. The method of claim 1 , wherein receiving the listening intent preference comprises receiving a preference to enhance speech.
