title: Real-time detection of auditory steady-state responses.
abstract: Detection of the auditory steady-state responses (ASSRs) is a difficult task, its main technical impediment is no other than the excessively lengthy recording time required for the estimation process due to the extremely low signal-to-noise ratio (SNR). To improve the detection rate of ASSRs, a new observer-based real-time ASSR detector is derived as an alternate solution to the existing methods. The ASSR detector has a simple structure, and provides fast and reliable signal detection. Simulation and experimental recorded data were used to evaluate the performances of the proposed approach. Compared with the conventional methods, the proposed method requires shorter recording time which could be proven as a valuable hearing screening or diagnostic tool.
