6.3 DSL Verification

There are two ways to verify that the hearing aid meets the DSL prescription:

through coupler measurements and through real-ear measurements. In the DSL

window, you can view the coupler and real-ear targets in dB GAIN or dB SPL.

When displaying in dB SPL, you can also view the patient’s thresholds, upper

limits, and the LTASS. Coupler and real-ear measurements can be performed

and compared to the displayed targets. See Figure 6.3.
