CALIBRATED DIGITAL HEADSET AND AUDIOMETRIC TEST METHODS THEREWITH
摘要
A digital headset system for use in audiometric testing. The headset system includes a stored calibration reference relating the exact frequency and volume response of each speaker to analog input signals. A microprocessor accesses the calibration reference to determine the required analog signal needed to produce the desired sound. An on-board digital to analog converter generates the required analog signal and transmits it to the speaker. The headset is used with software based audiometric test methods that allow the generation of an electronic user hearing profile. The user hearing profile may be used to re-program an audio emitting device to function in a customized manner. The user hearing profile may be overlaid on a partner hearing profile in order to emulate for the partner how sounds are perceived by the user. The test methods may be self-administered or administered by a healthcare professional.
