Claim:
1. 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.
