Relative to @platypus’s complaint that Spheric noise reduction wouldn’t turn on, if one creates either a linked or a copied manual copy of Spheric Speech in Loud Noise, then in the MyPhonak app, you can turn Spheric processing on at any time. Invoking the program manually doesn’t depend on the noise environment. And you can see the effect by playing back the various Target media samples of speech in low SNR environments through your computer speakers.
At home, though, I haven’t been able to manufacture any noise environment that gets Spheric processing to turn on automatically in AutoSense. It would be great if someone could come up with an easy-to-emulate-in-your-home test scenario so one doesn’t have to go to a noisy bar or restaurant to test out various program modifications to the Spheric Speech in Loud Noise program.
The following website has a number of non-English speech in noise samples: SFX - Restaurant, Outdoor, Busy, Spanish Walla, Children, Music | Epidemic Sound
One of the better examples there that you can clean up considerably by invoking manual Spheric processing in the MyPhonak app is the following speech sample: SFX - Outdoor, Spanish Walla Close, Busy, Spain | Epidemic Sound
