title: A direct method of estimation of stimulus frequency otoacoustic emissions.
abstract: A novel technique of direct estimation of stimulus frequency otoacoustic emission (SFOAE) signals is proposed. SFOAE signals have been the subject of much research because of their value in providing information about the structure and health of the human auditory system. Current methods of estimation of SFOAE signals are indirect in the sense that the use of suppressor tones is inevitable and the SFOAE signals are estimated indirectly by virtue of a nonlinear residual time-domain technique. Conventional signal processing techniques do not provide any means of direct estimation of SFOAE signals given that both the stimulus and the otoacoustic emission are at the same frequency. The studies conducted through testing of the proposed SFOAE estimation technique on simulated data show good performance of the proposed technique.
