The NAL-NL1 Fitting Method Ted Venema Hearing Aids ...Feb 26, 2001 · NAL-NL1 compared to DSL (and some other methods): Most of the following discussion pertains to the differences between NAL-NL1 and the DSL fitting method. It should be noted that for any comparison with DSL, gain targets have to be converted to output targets, or vice versa. The DSL method normally plots its targets in terms of output, not gain.
