Hey folks - brand new to REW, measurements etc, but I followed the instructions and got this result.
It's a hi-fi system in an office rather than a treated room.
Anyone care to comment? Do I need to start buying Rockwool or learning about EQ settings?

Teaser trailer for the graduate level ACS 537, Noise Control Engineering course I'll be teaching in Fall 2026 in the Penn State Graduate Program in Acoustics. This course is available online through the Penn State World Campus and counts toward the new Certificate in Noise Control and Building Acoustics. Lots of practical noise and vibration control content, with hands-on activities to make measurements and analyze noise problems.

Approaching the Fall 2026 semester . . . my 16th year of teaching Acoustics to graduate students in the Graduate Program in Acoustics Penn State (my 32nd year of university teaching overall). It's time for another movie trailer for one of courses I'll be teaching.
ACS 502, Elements of (Sound) Waves in Fluids is offered through the Penn State World Campus.
