Abstract
Methods and systems for sensing an auditory environment using a tympanic membrane of an individual are disclosed. An embodiment of a method comprises a step of dynamically sensing a displacement of the tympanic membrane in response to excitation by the auditory environment. An electrical signal based upon the sensed displacement is produced. Consequently, the electrical signal is representative of the auditory environment as sensed by the individual. Embodiments for sensing the displacement of the tympanic membrane are based upon laser interferometry and ultrasonic ranging. Further disclosed are methods and systems for modifying a sensed auditory environment, and methods and systems for producing a virtual auditory environment based upon directly sensing the displacement of the tympanic membrane of an individual.
