@JordanK nailed one of the best places to test Spheric noise reduction. Today, my wife wanted to get a new iPhone. The Apple Store was just as Jordan described the one he visited. I’ve reduced my Spheric noise processing trigger threshold to a moderate noise level, but other places I’ve visited haven’t been noisy enough, apparently, to automatically trigger Spheric processing. Today in the Apple Store, Spheric noise reduction came on automatically the whole time I was in the store, and it worked great. Using the Adjust Program tab, I could change speech focus to narrow and better hear the rep helping us by looking at him and thus hearing less of all the other people close by carrying on their own separate conversations.
