✓

Answer

  1. Multiple reflections

Explanation:

Reverberation is the phenomenon of persistence of sound after it is stopped by surfaces such as furniture, people, walls, etc. within a closed space, causing multiple reflections. These reflections build up with each reflection and persist for a finite time and then decay gradually as they are slowly absorbed by the objects in the space enclosed.
