Live Speech Mapping—Advancing to the REAR?
Mr. Michael Poe
Real Ear Measurements are essential for verifying hearing aid fittings. The enhanced features in new real ear measurement instrumentation also provide exceptional tools for the Dispenser.
Today's presentation provides a quick review of Real Ear Measurements, an update on Loudness Scaling, and an introduction to the NEW dynamic features in current instrumentation. A real ear measurement protocol will be recommended.
ANSI Terminology—reviewed
- REUR
- REAR and RESR
- REIR and REIG
- REOR
- Occlusion Effect
Loudness Scaling
- Current procedures—IHAFF and RELS
- How to use Loudness Scaling results to set compression kneepoint and ratio, when fitting WDRC nonlinear hearing aids, using Real Ear Input/Output measurements.
- Instrumentation for Real Ear Measurements and Loudness Scaling
- Standard functions: REUR, REIR/ REIG, REAR, RECD, REOR
- Enhanced features: Integrated Loudness Scaling and Real Ear Measurements, "Random Stimulus" options for measuring adaptive circuits in hearing instruments; .real time" Live Speech input mode; Automated Occlusion Effect task; real ear measurements in "real time" while making hearing aid programming changes.
A Real Ear Measurement Protocol
- REUR
- REAR using "Live Speech" on the Aided Speech Spectrum target
- Mapping the Auditory Area for patient's with tolerance problems
- Matching Gain To Comfort levels
- Limiting Output to below Uncomfortable levels
- Use the REIG and prescriptions as a guide and start point
