In acoustics, reverberation refers to the persistence of sound in a particular space. It is a result of multiple reflections and interactions with the dimensions and surfaces surrounding the sound source.
A known phenomenon is the footfalls observed in expansive, echo-prone rooms where, paradoxically, our senses might detect auditory clues better suited to the company of otherworldly entities.
Consider the dimensionless aspects of sound waves themselves: they traverse through time, yet they define their own spatial constraints as they proliferate through breezeways and reflective corridors.
Several factors influence the reverberation time (RT60), most notably room geometry, surface materials, and the volume of space. Despite the scientific analysis, variable anomalies sometimes suggest we aren't alone within reverberous phenomena.
