Footnote: The Frequency Output was tested using simulated real-ear measures consistent with best practice hearing aid verification procedures. The Signal-to-Noise Ratio ratings were based on expected improvement in SNR given the processing approach. For Listening Comfort, a true noise reduction algorithm is best; however, ‘Low internal noise’ as measured via electroacoustic analyses indicates no unpleasant ciruit noise and so was included as a comfort feature.
