Does anyone have a link to the original data for Phonak’s “speech-in-noise” study with the Sphere? Was this an independent double-blind study published in a peer-reviewed journal, who were the volunteers and what was the noise type, or was this just done “internally” with an in-house fanclub?
Just remember that for centuries people believed that Stradivarius violins sound better than anything produced since, until the instruments were properly tested…
