8 month old puppy now suspicious of and reactive to noises/people

Suggestions?  I'm doing the "let's go see" and praising and feeding for calm behavior and looking at me.  She was wary of people as a young pup but we worked on it and as been very social
I know she's an adolescent and this is hopefully a phase  and I'm doing what I tell my students but I want to pick the brains of this group of experienced trainers.  Thanks.
