ISO 3382: The Complete Guide to Room Acoustic Measurement
Master ISO 3382 room acoustic measurement — RT60, EDT, C50, C80 parameters explained with field examples, equipment lists, and common pitfalls.
What is an Impulse Response in Acoustics?
An impulse response captures a room's complete acoustic fingerprint — how it responds to a perfect instantaneous sound. Learn how IRs are measured, what they reveal, and how they drive room analysis.
What is the Schroeder Integration Method?
The Schroeder integration method converts a noisy impulse response into a smooth energy decay curve for reliable RT60 measurement. Learn the math, history, and practical application of this technique.
Free ISO 3382 Measurement Procedure Card — Field Reference for RT60 Testing (PDF)
Step-by-step ISO 3382-2:2008 measurement procedure for field RT60 testing. Equipment checklist, position rules, T20/T30 criteria, data quality checks — one-page site reference.
How to Measure RT60: Interrupted Noise vs Impulse Response vs MLS
A practical comparison of the three ISO 3382-compliant methods for measuring reverberation time: interrupted noise, impulse response (balloon pop, starter pistol), and MLS/swept sine. Covers equipment requirements, measurement positions, T20 vs T30 vs T60 evaluation ranges, and common errors.
How to Measure Room Acoustics: Equipment, Methods, and What the Numbers Mean
Measuring room acoustics requires a sound source, a microphone, and analysis software — but the method you choose determines whether your results are valid. Here is a practical guide to acoustic measurement: from balloon pops to dodecahedron speakers, from smartphone apps to ISO 3382-compliant equipment.
