Just when I thought I was understanding this topic, another confusing response on a practice quiz..
My question is whether having sound absorbing panels on the 'receiving' side of a wall assembly located against a noisy room, helps increase the transmission loss of a wall assembly, or not.
In the attached sample problems, the explanation for question #105 states that adding sound absorbing panels on the noisy side would NOT affect transmission loss.
In the explanation for question #107, the explanation states that having absorption panels on the receiving side (so side B in this case) would help in increasing the transmission loss of the assembly.
Any thoughts would be appreciated.
