Which of the following interior items contributes to a comfortable acoustic environment?
A . Soft surfaces
B . Wood cabinets
C . Hollow metal doors
D . Glass cubicle partitions

Answer: A

Explanation:

Soft surfaces contribute to a comfortable acoustic environment by absorbing sound waves and reducing noise levels. This can include items such as carpets, upholstered furniture, and acoustic ceiling tiles. In contrast, hard surfaces (like wood cabinets, hollow metal doors, or glass partitions) can reflect sound waves and increase noise levels.
