Table 3.

Mean deviation of user frequency response slope (averaged over 0.5 to 4 kHz, expressed in terms of dB/octave) from prescribed response slopes (User slope minus target slope). Deviations are shown for low (50 dB SPL), medium (65 dB SPL) and high (80 dB SPL) input levels. Also shown are standard deviations (SD) and range (Min-Max).

	SD	1.6	1.7	1.6
	Min-Max	−3.0 to 3.0	−4.7 to 2.0	−6.3 to 2.3
DSL m[i/o] (n = 57)	Mean	−0.6	−1.2	−0.6
	SD	2.4	2.5	2.0
	Min-Max	−9.7 to 3.7	−10.0 to 2.7	−6.3 to 2.7
NAL-NL1 (n = 108)	Mean	0.3	0	0.5
