The Audioscan RM500 Speechmap/DSL Fitting System
William A. Cole, Sheila T. Sinclair · Trends in Amplification · 1998
The Speechmap/DSL fitting system is an integrated approach to fitting hearing aids that takes advantage of the signal generation and measurement capabilities of the Audioscan RM500 real-ear hearing aid analyzer. By combining auditory-area mapping with unique, time-varying test signals and fast automated RECD and REDD measurement procedures, it provides a complete fitting package that addresses many of the sources of error inherent in more traditional methods.
