Abstract
A method for providing personalized ambient sound playback, ASP, calibration data associated with an audio device and a specific user is presented. The methods comprises processing a digital representation of a first specific external sound based on an initial set of frequency dependent processing parameters and generating, by the audio device when worn by the specific user, a first internal sound based on the processed digital representation of the first specific external sound. The method further comprises adjusting the initial set of frequency dependent processing parameters based on obtained first feedback data and providing these as ASP calibration data for the audio device when worn by the specific user.

A method for providing personalized ambient sound playback, ASP, calibration data associated with an audio device and a specific user, the method comprising:
- generating, remotely from the audio device, a first specific external sound within a first frequency band;
- obtaining, by the audio device, a digital representation of the first specific external sound;
- processing the digital representation of the first specific external sound based on an initial set of frequency dependent processing parameters;
- generating, by the audio device when worn by the specific user, a first internal sound based on the processed digital representation of the first specific external sound;
- obtaining, from the specific user, first feedback data indicative of a similarity between the first internal sound and the first specific external sound;
- adjusting the initial set of frequency dependent processing parameters based on the first feedback data and the first frequency band, thereby obtaining a personalized set of frequency dependent processing parameters;
- repeating the steps of generating, obtaining, processing, generating and obtaining, for a second specific external sound within a second frequency band thereby obtaining second feedback data associated with the second specific external sound and the second frequency band,
- wherein the personalized set of frequency dependent processing parameters are further adjusted based on the second feedback data and the second frequency band;
- and
- providing the personalized set of frequency dependent processing parameters as ASP calibration data for the audio device when worn by the specific user.
An audio device configured to provide ASP calibration data of the audio device and a specific user, wherein the audio device comprises a feed forward microphone circuit, a transducer circuit, and a processor circuit, wherein the processor circuit is configured to cause execution of the steps of:—
- obtaining, by the feed forward microphone circuit of the audio device, a digital representation of a first specific external sound within a first frequency band generated remotely from the audio device;
- processing, by the processor circuit, the digital representation of the first specific external sound based on an initial set of frequency dependent processing parameters;
- generating, by the transducer circuit when the audio device is worn by the specific user, a first internal sound based on the processed digital representation of the first specific external sound;
- obtaining, by the processing circuit, first feedback data provided by the specific user through a feedback provisioning circuit, wherein the first feedback data is indicative of a similarity between the first internal sound and the first specific external sound;
- adjusting, by the processing circuit, the initial set of frequency dependent processing parameters based on the first feedback data and the first frequency band, thereby obtaining a personalized set of frequency dependent processing parameters;
- repeating the steps of obtaining, processing, generating and obtaining, for a second specific external sound within a second frequency band thereby obtaining second feedback data associated with the second specific external sound and the second frequency band,
- wherein the personalized set of frequency dependent processing parameters are further adjusted based on the second feedback data and the second frequency band;
- and
- providing the personalized set of frequency dependent processing parameters as ASP calibration data for the audio device when worn by the specific user.
