Let me clarify what Chuck said based on my understanding.
Let’s say Chuck has a default program 1, then let’s say his program 2 in the More is My Music, and program 3 is Speech in Noise, and program 4 is Tcoil (all just hypothetical here because I don’t really know what Chuck has on his More 1), then if Chuck is using program 1 by default and he attends a live music concert or crank on the music at home, the Oticon More will NOT transition from the default program 1 to the My Music program 2. By the same account, if he goes to a restaurant and he’s in program 1, his More aids will NOT switch to the Speech in Noise program 3 once inside a restaurant. If Chuck attends church and it has an audio loop for the tcoil, if Chuck doesn’t manually change his program to the Tcoil program 4, his More 1 aids will remain in program 1.
But as long as Chuck is in the default program 1 and he’s happy with it in all kinds of environment (which is VERY feasible because of how Oticon designs their HAs like that), then it’s a set-it-and-forget-it thing because the default program 1 serves his every need for listening to music, being at home, at restaurants, outdoors, etc. Basically his program 1 makes all the adjustments within the same program to fit his various needs. But it does NOT automatically go from 1 program to another inside the More.
To clarify further, other brands that do some kind of environment autosense (like Phonak’s AutoSense feature), they will automatically switch from one program to another program if their AutoSense feature determines that the new environment is more suitable for a different program available in the aids. But the Oticon More will NEVER automatically switch from one program to another like the other brands’ Autosense does. The Oticon user MUST MANUALLY do the switching between the programs themselves.
Having said that, the Oticon is not considered to be deficient compared to other brands because of this. The Oticon approach is that they continually monitor the environments, and if they detect a change in the environment, they STAY within that program and automatically adjust the parameters within that program continuously to make it more effective. For example, if you’re in program 1 in the More (which is the general purpose program) and you go into the restaurant, the More will migrate its Neural Noise Suppression from a lower value to a higher value to help suppress the noise and improve the speech clarity, based on the range that you allow this NNS parameter to operate within.
For example, you set program 1 to have 2dB NNS max in Easy environment and 8dB max for NNS in Difficult environment, when you’re at home, the noise suppression would be between 0 to 2dB. Perhaps if you’re alone in your office, it’d be set to 0dB NNS. If you’re in the kitchen with your wife and kids talking now and then, perhaps it’ll set to 2dB NNS. Now you go into a restaurant, if it’s a relatively slow time, but enough for the More to consider that you’re now in a difficult environment, then perhaps it’ll set the NNR to 4dB. Then as it gets busier and noisier, perhaps it’ll go up to 6dB, then at peak time, it’ll go up to 8dB which is the max value you allow it to go up to.
Now you ask then what’s the difference between the default program 1 and the built-in Speech in Noise program then? Well, perhaps the difference is that your audi only sets the NNR max in your default program 1 to 8 dB, but in the Speech in Noise program, your audi goes up to the top notch of 10 dB. So maybe most of the times you’re in a restaurant, the top NNR of 8 dB is enough for your hearing to function satisfactorily. So you stay in program 1 either at home or at a restaurant most of the time → it’s a set it and forget it situation. But maybe once in a while, you find yourself in an extra crowded restaurant and what you have in program 1 of 8dB NNS max is no longer good enough. Then that’s when you’d have to manually switch to the Speech in Noise program 2 to get that extra help from the 10 dB NNS max value.
Hope this clarifies things.
