Step 1. Simply select the patient's experience level and open versus closed coupling, and Compass GPS will automatically select the first fit profile best for your patient.
Step 2. During the feedback test, the Widex vent compensation assessment evaluates five physical parameters to provide optimal gain for audibility:
- Vent length
- Vent diameter
- Ear canal volume
- Leakage around the ear-tip or shell
- Tympanic compliance
The Widex Sensogram uses in-situ testing to provide a more personalized first fit. In-situ testing accounts for the patient’s hearing loss as well as ear canal resonance for better fitting accuracy.Download the Compass GPS Quick Fitting Guide for more information
