Maybe they were rounding (up) to the nearest 1 KHz
The frequency response of the Oticon receivers as stated in the technical data sheet for the various models hasn’t really changed much since the OPN. The following response numbers are for 85 dB receivers for the 1 version in an “Ear simulator” as found in the technical data sheet:
OPN 1 120-9500
OPN S 1 120-9500
More 1 100-9500
Real 1 100-9500
Intent 1 100-9400
The response for a different testing device (2CC Coupler) is typically more compressed (lower high frequency cutoff). Some models are shown with a slightly higher cutoff for the 60 dB receivers (More 1 is 9600 for example). There is also a statement that the fitting bandwidth for the 1 versions is 10kHz with a footnote of “Bandwidth accessible for gain-adjustments during fitting”.
Note - the high end frequency response is falling off quickly and the use of a log scale for frequency accentuates this in the graphs. I typed in the values for the 85 dB receivers as I have the sheets for those which I downloaded when I was using them.
I’m probably not going to update my Real 1 aids until LE Audio and Auracast are a bit more mature and available on a wider range of devices (phones and computers and hearing aids) and interoperability is better. I lived through trying to make WiFi work when it first came out - very frustrating for quite some time with lots of firmware updates for both AP and clients that fixed some things and broke others …
