Abstract

The feasibility of utilizing maximum length sequence analysis (MLSA) with newborns was examined on 40 premature infants residing in a neonatal intensive care unit (NICU). Auditory brainstem responses (ABRs) were initially obtained using a conventional stimulus rate of 33.3/sec. Using MLSA, responses were also recorded using much faster stimulus rates (227.3/sec, 454.5/sec, and 909.1/sec). As expected, faster stimulus rates resulted in longer ABR component wave latencies. Less expected was the clarity of the ABRs that were obtained through MLSA. Well-defined responses were obtained from premature infants at all stimulus rates. The findings suggest that MLSA may have clinical applications to newborn hearing screening.
