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.
