– In an enclosed space, sound waves reflect repeatedly from walls, ceilings, and other surfaces.
– Reverberation is the persistence of sound after the source has stopped, caused by these multiple reflections delaying the sound’s decay.
– Refraction is the bending of waves as they pass from one medium to another.
– Diffraction is the bending of waves around obstacles or through openings.
– While reflection is the mechanism, the *persistence* of sound due to these multiple reflections is specifically termed reverberation. Excessive reverberation can make sound unclear in large halls.
