Technical Notes
Eyring Correction
For rooms where average absorption > 0.3 (VO Live, Control), Eyring correction gives more accurate results than Sabine. Both methods are shown in the Main Report.
Why Each Room Has Its Target
VO Live (0.20s): Voice recording needs minimal coloration.
Control (0.30s): Mixing requires neutral monitoring environment.
Studio (0.25s): Video production needs controlled but not dead acoustics.
Editing (0.36s): Post-production tolerates more reverb — NC-25 target.
