Sound attenuation refers to what?

Decreasing noise from surrounding areas; can be blocked with trees Increasing interior noise The speed of sound through steel The acoustical quality rating of a room

Correct Answer:

Decreasing noise from surrounding areas; can be blocked with trees

Explanation:

Sound attenuation is about reducing the amount of sound that travels from one place to another, especially through barriers between outside and inside spaces. The idea described here—decreasing noise from surrounding areas and using barriers like trees to block it—fits this concept because it reflects lowering external sound levels before they reach an interior space. The other statements don’t fit attenuation: increasing interior noise describes amplification or poor isolation; the speed of sound through steel concerns how fast sound travels in a material, not how much is reduced; and the acoustical quality rating of a room relates to how sound behaves inside a space rather than how well external noise is blocked.
