Many current ABR screeners are stimulating at more than double the rate, are using different stimulus types (i.e. wideband chirp, ASSR) and different montages than what was originally envisioned in the early guidelines, resulting in significant reduction of test time and potentially fewer refers. Although advantageous to the screening and diagnostics community, are these new techniques screening for the same previously targeted hearing loss? This presentation will summarize investigations into the effect of stimulus rate, stimulus type, and montage.
