Answer:
Reverberation refers to the persistence of a sound long after a sound is produced. It is the collection of reflected sounds from nearby surfaces in smaller enclosures.
To reduce reverberation, sound waves must be absorbed as soon as they touch a surface. So, we have to provide sound-absorbing surfaces.
i. Cover the floor with thick carpet
ii. Hang up heavy drapes and wall art from the ceiling
iii. Heavy curtains and cushioned seats
iv. Fibreboard
Step-by-step explanation:
To reduce the reverberation that occurs in classrooms, here are some recommendations:
- Install acoustic panels: These are specialized panels made of sound-absorbing materials such as foam or fiberglass that can be mounted on walls and ceilings to reduce sound reflection and absorption.
- Use sound-absorbing materials: Use materials such as carpet, curtains, and upholstered furniture to absorb sound waves and reduce reverberation.
- Position furniture strategically: Arrange desks, chairs, and other furniture in a way that minimizes sound reflection and absorption. For example, placing bookshelves or cabinets along the walls can help absorb sound waves.
- Use sound barriers: Install sound barriers such as partitions or screens to block sound waves from bouncing around the room.
- Modify the ceiling: Installing a suspended ceiling or hanging acoustic tiles can help absorb sound and reduce reverberation.
By implementing these recommendations, the reverberation in classrooms can be significantly reduced, creating a more comfortable and conducive learning environment for students and teachers alike.
