A three-dimensional, head mounted microphone array is employed to isolate and analyze intracranial sound sources such as may provide for objective tinnitus. The microphone array allows a region of interest within the patient's head to be isolated for the detection of sounds and allows episodic sounds to be automatically identified as to location. An interactive display allows a better understanding of sound locations and the extracted sounds can be analyzed with respect to a library of sounds linked to particular locations and diagnoses.
