Many in the community mentioned that there are a lot of acoustics questions in PDD. I had same feeling after I took PDD in February. But what is most frustrating, I couldn't find much study materials for acoustics. I have not done much work in acoustics at all.
I felt what I studied for acoustics was so much different from what they asked in PDD.
Can anyone recommend study materials: Ballast, Fundamental Building Construction, or Building construction illustrated?
