I did not understand the answer to Q#3; why would you need more surface area with a higher NRC? The course was very clear and the presenter spoke very well, I enjoyed the course.

This was a very interesting course but also hard to keep up with. A lot of information was conveyed, and I now have a basic understanding of acoustics.

Wow! A tremendous amount of information is packed into this 1-hour course. Thank you.

This course was very informative, but the speaker spoke very quickly and I had to pause several times to absorb the information presented.

I found this course to be very informative and helpful in understanding Acoustic Solutions
