What name is given to the persistance of sound in a big hall or auditorium?

Options

A. Reverberation
B. resonance
C. acoustics
D. articulation

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name given to the persistence of sound in a large space, such as a hall or auditorium.

2. **Concept of Sound Persistence**: In acoustics, the persistence of sound refers to how sound continues to be heard even after the source has stopped producing it. This is often due to reflections off walls and other surfaces in a large space.

3. **Identifying the Term**: The specific term used in physics to describe this phenomenon is "reverberation."

4. **Explanation of Reverberation**: Reverberation occurs when sound waves reflect off surfaces in a room, causing the sound to linger for a period of time. This is particularly noticeable in large halls or auditoriums where sound can bounce off walls, ceilings, and floors.

5. **Conclusion**: Therefore, the name given to the persistence of sound in a big hall or auditorium is "reverberation."
