Abstract
A method of determining an audio controller for a headphone that is configured to use an acoustic transducer to develop sound that is delivered to an ear of a user and that includes a feedback microphone that is configured to sense sound developed by the acoustic transducer, and a related computer program product and system. A first audio transfer function between the acoustic transducer and the feedback microphone is measured. A second audio transfer function between the acoustic transducer and the feedback microphone with a feedback controller applied is determined. The audio controller is calculated based on both the first audio transfer function and the second audio transfer function.

A method of determining an audio controller for a headphone that is configured to use an acoustic transducer to develop sound that is delivered to an ear of a user and that includes a feedback microphone that is configured to sense sound developed by the acoustic transducer, the method comprising:
- measuring a first audio transfer function between the acoustic transducer and the feedback microphone;
- determining a second audio transfer function between the acoustic transducer and the feedback microphone with a feedback controller applied;
- and
- calculating the audio controller based on both the first audio transfer function and the second audio transfer function.
A computer program product having a non-transitory computer-readable medium including computer program logic encoded thereon that, when performed on a headphone that is configured to use an acoustic transducer to develop sound that is delivered to an ear of a user and that includes a feedback microphone that is configured to sense sound developed by the acoustic transducer, causes the headphone to:
- measure a first audio transfer function between the acoustic transducer and the feedback microphone;
- determine a second audio transfer function between the acoustic transducer and the feedback microphone with a feedback controller applied;
- and
- calculate the audio controller based on both the first audio transfer function and the second audio transfer function.
