Abstract
Technology for dynamic characterization of a communication device is disclosed. One method comprises sending an acoustic characterization excitation signal to be output by an acoustic transducer in the communication device. A received acoustic coupling signal that is received by a microphone of the communication device in response to the output of the acoustic transducer is measured. An acoustic signal conditioning algorithm is applied to at least one of the microphone or the acoustic transducer to reduce an amplitude of the acoustic signal or the received acoustic coupling signal to a level below a selected threshold.

A method for dynamic characterization of a communication device, comprising:
- sending an acoustic characterization excitation signal to be output by an acoustic transducer in the communication device;
- measuring a received acoustic coupling signal that is received by a microphone of the communication device in response to the output of the acoustic transducer;
- applying an acoustic signal conditioning algorithm to at least one of the microphone or the acoustic transducer to reduce an amplitude of the received acoustic coupling signal to a level below a selected threshold to reduce feedback in full duplex communication of the communication device;
- and
- applying a dynamic signal conditioning algorithm to compensate for changes in at least one of the acoustic transducer or the microphone that occur over time and identifying when a component has failed based on the changes in at least one of the acoustic transducer or the microphone to enable the components to be repaired or replaced.
A communication device comprising:
- a speaker transducer operable to output an acoustic characterization excitation signal;
- a microphone transducer operable to measure a received acoustic coupling signal in response to the output of the speaker transducer;
- a processor configured to apply an acoustic signal conditioning algorithm to at least one of the microphone or the acoustic transducer to reduce an amplitude of the received acoustic coupling signal to a level below a selected threshold to reduce feedback in full duplex communication of the communication device;
- and
- applying a dynamic signal conditioning algorithm to compensate for changes in at least one of the acoustic transducer or the microphone that occur over time and identifying when a component has failed based on the changes in at least one of the acoustic transducer or the microphone to enable the components to be repaired or replaced.
