TABLE II.

Three measures of bandwidth for the three types of filter, cascade cGC, parallel roex, and parallel cGC; the values are for the filter centered at 1.0 kHz and they are presented for two stimulus levels, 40 and 80 dB. The three bandwidth measures are the equivalent rectangular bandwidth (ERB), the 10-dB bandwidth, BW_{10 dB}, and BW90, the 90% bandwidth suggested by Kollmeier and Holube (1992).

	ERB		BW90		BW_{10 dB}
	40 dB	80 dB	40 dB	80 dB	40 dB	80 dB	Average
Cascade cGC filter	196	278	275	416	340	492	333
Parallel roex filter	147	220	252	433	281	451	297
Parallel cGC filter	152	241	229	398	270	440	288
Average	165	246	252	416	297	461	306
