The Environmental configuration is simply the choice between Very Simple, Simple, Moderate, Complex and Very Complex. The More 1 and 2 have 5, the More 3 has 3 (lacks the Very Simple and Very Complex → no big deal). These let you define which of them are part of the Easy Environment and which are part of the Difficult environment so that the parameters in the MoreSound Intelligence would fall under which and which.
The Virtual Outer Ear has Aware, Balanced and Focused for the More 1, and only 1 configuration (Balanced) for the More 2 and 3. This basically models the Outer Ear for the case of the Simple environment configuration. It’s really no big deal to miss the Aware and Focused. You hear more around you with Aware, you hear less (and more in front) with Focused. The Virtual Outer Ear is how to filter sounds before sending the sound scene signal into the DNN for processing, in the case the environment is classified as “Easy”. In the case the environment is classified as “Difficult” by the user, the Virtual Outer Ear is not used. Instead, the Spatial Balancer (noise reduction of well placed noise sources) is used for Difficult environments.
The Spatial Balancer was already covered in the previous posts. It’s an important MVDR beam forming functionality that would help attenuated well placed noise sources. The More 1 has 100% functionality, while the More 2 and 3 have only 60% functionality. It’s not clear what the percentage means. I’m assuming that it probably means the amount of attenuation → the More 1 attenuates 100% of what it should attenuate, while the More 2 and 3 attenuates less than they should/can.
The Neural Noise Suppression for Difficult/Easy for the More 1 are 10/4, More 2 are 6/2, More 3 are 6/0. Note that these are max levels. It doesn’t mean that the More 1 always get more aggressive NNS than the More 2 and 3. Actually for the most part, they all get the same NNS until more than 6 dB is needed, then the More 1 MAY get more BUT ONLY IF you select more than the 6 dB default that Oticon recommends for the More 1. But if set at the default 6 dB, then the More 1 doesn’t do any more NNS than the More 2 or 3.
The Sound Enhancer has 3 configurations (Detail, Balanced and Comfort) for the More 1. I covered what they mean in great details in a post earlier in this thread. The More 2 only has Balanced and Comfort. The More 3 only has Comfort.
The Spatial Sound gives the More 1 4 Estimators while the More 2 and 3 have only 2 Estimators. Spatial Sound LX is the feature to give the patient a sense of direction on where the sounds are coming from. Without going into the details of what an spatial estimator is, the 4 estimators allow a separation of the spatial cues into 4 equally distributed frequency channels so that you can get more details on the spatial cues if they happen to be in different frequencies. With only 2 estimators in the More 2 and 3, there’s less details on the spatial cues in only 2 frequency bands. I would say this may or may not be important to you depending on whether it’s important to you to know where the sounds are coming from. You do have that with the More 2 and 3, but the More 1 will give you the best spatial cues available.
The fitting bandwidths of 10 KHz for the More 1 and 8 KHz for the More 2 and 3 is not really a big deal, because most of us can’t really hear worth anything beyond 8 KHz anyway. It may only help for those who still have very good high frequency hearing to be able to discern this kind of difference.
The 64 processing channels on the More 1 vs 48 channels on the More 2 and 3 is probably not really significant either. It used to be that 16, then 24 processing channels was plenty good, so I’m not sure if your ears can really discern the details that 64 channels can bring over 48 channels anyway.
Transient Noise Management has OFF/Low/Medium/High for the More 1 and only OFF/Low/Medium for the More 2 and 3. Transient noise management is used to remove discomfort due to sudden loud sounds without sacrificing speech audibility. I don’t think it’s a big deal if the More 2 and 3 can give a little bit less comfort on the More 1 here.
The More 1 has 24 fitting bands, the More 2 has 20, and the More 3 has 18 bands. It used to be that the OPN 1 has only 16 fitting bands. Fitting bands is the granularity of how you can adjust the gain across the frequency range for your Fine Tuning section. I think 16 is more than enough and 24 is overkill anyway.
