Acoustic flutter is the flashing echo effect in large rooms measuring 25 square meters or more, when there are two parallel smooth walls or a ceiling and a floor , between which there is a sound source. [1] [2]
As a result of multiple reflection at the point of reception, the sound is periodically amplified, and on short pulsed sounds , depending on the frequency components of the echo and the interval between them, it acquires the character of bounce , crackling, or a series of sequential and decaying echo signals.
