Flutter Echo: Causes, Detection and Treatment
Understand what causes flutter echo between parallel surfaces, how to detect it with a clap test or measurement, and proven treatment strategies for any room.
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 Sound Reflection?
Sound reflection occurs when sound waves bounce off a surface. Learn how reflection creates reverberation, flutter echoes, and standing waves — and how to control it in room design.
The 15 Acoustic Design Mistakes Architects Make — And the Standard Clauses That Prevent Them
15 specific acoustic design errors that architects commonly make, each matched with the exact standard clause that would have prevented it. Covers NRC misuse, low-frequency neglect, parallel wall flutter echo, soundproofing vs treatment confusion, HVAC noise, glass overuse, ceiling-only treatment, room modes, Sabine misapplication, occupancy effects, and flanking transmission. Includes worked examples and remediation costs.
