What is a Decay Curve? (Measuring RT60)
A decay curve shows how sound energy decreases over time in a room. Learn how decay curves are generated, how RT60 is extracted from them, and why the Schroeder integration method is preferred.
What is Echo? (And How It Differs from Reverberation)
An echo is a distinct, delayed repetition of a sound caused by reflection from a distant surface. Learn the 50 ms threshold, how echoes form, and how acoustic design prevents them.
What is Reverberation? (vs Echo vs Delay)
Reverberation is the persistence of sound in a room after the source stops, caused by thousands of overlapping reflections. Learn how it differs from echo and delay, and why it shapes every room.
Swimming Pool Acoustics — The Hardest Room in Architecture to Fix | AcousPlan
Natatorium theoretical RT60 reaches 12.8s. Moisture-resistant treatment comparison (PET vs metal vs fiberglass). Emergency PA STI ≥ 0.45 requirement.
Church Acoustics: When RT60 Goes From 'Cathedral' to 'Unusable'
Cathedral RT60 of 8+ seconds is acoustically magnificent and completely unintelligible. Here's how to design worship spaces that serve both organ music and the spoken word.
Church Reverberation — The Impossible Balance Between Speech and Music
Churches need RT60 of 1.0s for speech and 3.0s for organ music — in the same room. Here are 4 solutions that actually work.
Mosque Acoustics Design Guide — RT60, STI, and the Dome Problem
A complete guide to mosque acoustic design. Solve dome focusing, marble reflections, and PA system conflicts. With worked calculations per ISO 3382.
Why Does My Room Echo? The Physics, the Diagnosis, and the Fix
Room echo is caused by insufficient acoustic absorption — specifically when RT60 exceeds 0.8s in a space designed for speech. Here is how to diagnose which surfaces are the problem and fix it for under £500.
Room Acoustics Fundamentals: How Sound Behaves Inside a Room
Sound in a room does not simply travel from source to listener. It reflects off every surface, arrives at the listener hundreds of times with different delays, and creates a complex acoustic signature. Here are the fundamentals of room acoustics — from direct sound to late reflections to standing waves.
