We audiologically assessed newborn and infant hearing loss in 45 babies and infants from April 2003 to April 2004. To examine ABR and MASTER, the coefficient of correlation for 4kHz was 0.876, and 0.891 for 2kHz. The MASTER result (mean±SD) in passes in AABR is 0.5kHz: 39±7HL, 1kHz: 30±9HL, 2kHz: 32.5±10HL, and 4kHz: 31.2±10HL. The MASTER result (mean±SD) of passes in DPOAE was 0.5kHz: 39±12HL, 1kHz: 32±12HL, 2kHz: 29±10HL, and 4kHz: 33±9HL. For ABR, it (mean±SD) was 33±9nHL. From our data, MASTER has the advantage of frequency peculiarity and inspection time is short by simultaneous measurement in the left and right ear. We also examined MASTER under natural sleep after AABR.
