Hidden Variables: Understanding Reverberation Time Calculation

VENUE UPDATE:

YMCA Board Room, YMCA - Sixth Street Milton Keynes MK92NR

About the Talk

PLEASE NOTE, THIS MEETING WILL START WITH THE CENTRAL BRANCH AGM.

Despite standardisation through BS EN ISO 3382-2 and BS EN ISO 354, reverberation time measurement permits significant procedural flexibility whilst maintaining compliance with standards. This flexibility includes choices around sample rate, averaging methods, averaging time, and determination of the initial "steady level". These processing variables are often hidden within proprietary sound level meter algorithms, meaning practitioners may be unaware of their impact on results. This presentation systematically examines the signal processing stages involved in calculating reverberation time, using real measurements from real rooms with both impulsive and interrupted pink noise sources. The findings highlight the importance of critically reviewing decay curves and regression lines before accepting measurement results.
