RT60 measures how long sound takes to decay by 60 dB after the source stops. Matching target RT60 values across octave bands ensures each room delivers its intended acoustic character, from the ultra-dry VO booth to the relaxed editing area.
VO Live: 0.18 - 0.25 s | Control: 0.33 - 0.40 s | Studio: 0.28 - 0.35 s | Editing: 0.42 - 0.50 s
Targets are frequency-dependent, tapering lower at high frequencies where absorption is easier to achieve. Heavily treated small rooms may use the Eyring correction for greater accuracy.
For rooms with average absorption coefficient > 0.4 (such as the VO Live booth),
the Eyring equation RT60 = 0.161 V / [-S ln(1-ā)] provides a
more accurate prediction. All achieved values above include Eyring corrections where applicable.
