Endpoint 1: Evaluation of Signal to Noise Ratio - Noise Reduction
Speech understanding in noise using AzBio sentences with and without the SNR - noise reduction algorithm enabled. Speech understanding at a fixed +10 dB signal to noise level in each condition (on/off) is scored as percent correct and then subtracted to demonstrate the percent difference (benefit) in performance of having the algorithm on vs off.
Time frame: Visit 2, 1 month after baseline testing
Endpoint 2: Evaluation of SCAN
Speech understanding in noise using AzBio sentences with and without SCAN algorithm enabled. Speech understanding at a fixed +10 dB signal to noise level in each condition (on/off) is scored as percent correct and then subtracted to demonstrate the percent difference (benefit) in performance of having the algorithm on vs off.
