Table 1

Accuracy of “normal” BC-ABR levels for classification of “normal” versus “elevated” cochlear status.

			BC-ABR results
			Normal	Elevated
2000 Hz	Behavioural outcome	Normal	28 (20.3%)	0 (0.0%)
138 ears		Elevated	3 (2.2%)	107 (77.5%)
500 Hz	Behavioural outcome	Normal	36 (61.0%)	0 (0.0%)
59 ears		Elevated	1 (1.7%)	22 (37.3%)

Percent of total ears in parentheses.
BC ABR “normal” levels: 30 and 20 dBnHL for 2000 and 500 Hz.
Data for the “certain” and “presumed SNHL” groups included.
