I’ve tried the Resound fitting software and, as mentioned elsewhere on here, the Ambio’s are not recognised. So, unless it’s tucked away under a different name in the Danalogic fitting software, I accept the Ambio 77’s don’t have it.
It is not on the regular Ambio, only the Ambio Smart.
I have a set of Ambio Smart’s issued by my local NHS hospital, to be honest I turn it off as it’s more annoying than anything for me.
That said, if you’re easily startled I can see it being a benefit.
Aside from Impulse Noise Reduction, you also miss out on Binural Directionality III + Spatial Sense and frequency adjustment up to 8Khz compared to 6.3Khz on the Ambio.
