Is reverberation caused by echo? Is echo the thing that we hear inside of our rooms? Or is it reverberation?
Once such definition states that -
Reverberation is the persistence of sound after the sound source has been stopped. It results from a large number of reflected waves which can be perceived by the brain as a continuous sound. On the other hand, an echo occurs when a pulse of sound can be heard twice.
Meanwhile the other one says -
An echo is a single reflection of a sound wave off a distance surface. Reverberation is the reflection of sound waves created by the superposition of such echoes.
I am also interested in knowing about what affects echo and reverberation. Like distance for echo must be around 16-17 m, right? But reverberations don't work that way right - as long as the sounds bounces off the walls? What about temperature? Surface of the reflected wall? Density of the medium? Humidity? Is that the same for reverberation as well?
