Reverberation Time and Room Acoustic Contribution
topic
Reverberation time testing measures the T20 or T30 decay time of broadband noise in a room with and without textile furnishings, calculating the equivalent absorption area contributed by upholstered seating, curtains, carpet, and wall panels using Sabine or Eyring reverberation equations across the 125 to 4000 hertz octave band range.
Role
Enables acoustic consultants to predict and optimise the speech intelligibility and music quality of auditoriums, classrooms, and offices by specifying textile element areas and absorption coefficients that achieve target reverberation times and room acoustic quality metrics.
