Hello All,

The below is a question from the BCPM & Systems (Mehta, 3rd Edition), Chapter 8.

And I thought the answer was (a.) True, however the review answer indicates (b.) False as the correct answer. How is that?, I thought dense materials are better sound barriers, can someone help me with these?

8. Compared to a lightweight building element, a heavyweight element
is generally a poor transmitter of airborne sound.
a. True b. False

  You are correct….and the question is correct too! A poor transmitter is also a good barrier. It’s a funnily worded question for sure.
