A method for in-situ transducer modeling in a digital hearing instrument is provided. In one embodiment, a personal computer is coupled to a processing device in the digital hearing instrument and configures the processing device to operate as a level detector and a tone generator. An audio signal generated by the personal computer is received by a microphone-under-test (MUT) in the digital hearing instrument and the energy level of the received audio signal is determined by the level detector. In addition, an audio output signal generated by the tone generator and a speaker-under-test (SUT) in the digital hearing instrument is received by a microphone, and the energy level of the audio output signal is determined by a level meter. The energy levels of the received audio signal and the audio output signal are used by the personal computer to generate an electro-acoustic model of the digital hearing instrument.
