Question

Trees must be removed from the road sides and around buildings to reduce the harmful effects of noise pollution.

• A. True
• B. False
• C. Ambiguous
• D. Data insufficient

Answer 1

Answer: (B)

False

Trees absorb and block noise and reduce glare. A well-placed tree can reduce noise by as much as 40 percent.

Vegetation reduces noise pollution through a phenomenon called sound attenuation, which is the reduction of sound intensity. Leaves, twigs, and branches on trees, shrubs, and herbaceous growth absorb and deflect sound energy.
