Lesson 1Clinical resources and evidence summaries from professional bodies (recommendations for REM use)Dis summarize guidelines from AAA, ASHA, BSA, and odas on verification. E go stress evidence for REM, recommended protocols, documentation, and how to put best-practice statements inside your daily clinic work.
Key AAA and ASHA REM recommendationsBSA and international REM guidanceEvidence comparing REM to first-fitBarriers to guideline implementationCommunicating best practice to patientsLesson 2Compression basics: attack/release times, number of channels, kneepoints, wide dynamic range compression rationaleE go explain compression goals and parameters, including attack and release times, channels, and kneepoints. E go talk about wide dynamic range compression, speech clarity, and how settings affect comfort, distortion, and verification.

E cover test signals, input levels, measurement conditions, and converting SPL to dB HL to make sure accurate, comparable verification results.
