The standard built-in Speech in Noise program does not have the Directionality Setting to Full Directional. It has it set to “Open Automatic”. If you set it to Full Directional, then you’re effectively putting it back into the paradigm of the old destination based system, where you block out the surround noise and will only hear the sound in the front.
Go to this link Podcast Program and watch the 2 podcasts called “Why Is Noise So Difficult?” and “Hearing Aid Technology and Noise”, in that order. You’ll find that the speaker (who’s a VP at Oticon) surmises that because the physiological deficiency of having less hair cells already cause hearing impaired people to have a hard time separating sounds (and effectively speech from noise), it’s actually better, especially in multiple speakers environments like at a restaurant, to present full information from all speakers to allow the brain hearing to do the separation and isolation, than to deprive the brain by blocking out sound from the multiple speakers. But putting your Directionality Setting to “Full Directional”, you’re effectively not helping the brain hearing by blocking out sound from the multiple speakers.
That is why the default value for Directionality Setting for Speech in Noise in Genie 2 is “Open Automatic” and not “Full Directional”. I leave my Speech in Noise program as is with “Open Automatic”.
