Hands-On: Acoustic Treatment, Part 2 Optimization with Insulation Elements
EVALUATE MEASUREMENT RESULTS
1 Understand Readings
After the measuring process, REW presents us the measuring results in the form of a three-dimensional frequency-response diagram. Its X-axis shows us not only the frequency response of the room impulse response, but also the level on the Y-axis. In addition, the Z-axis shows us the corresponding decay and reverberation time, which is a significant evaluation criterion for our room.
2 The Decay Time Matters
In the waterfall diagram, as well as in the view of the first measurement of the acoustically untreated room, the levels of the individual peak areas initially drop evenly. Ergo, our goal is
