Can noise pollution affect our sleep?

• Noise pollution only affects daytime activities, not sleep.

• Yes, noise pollution can negatively affect our sleep.

• Noise pollution has no impact on sleep quality.

• Noise pollution can improve sleep by masking other sounds.

Answer explanation

Yes, noise pollution can negatively affect our sleep by causing disturbances that lead to fragmented sleep patterns, increased awakenings, and reduced overall sleep quality.

What are some sources of noise pollution in cities?

• Traffic, construction, public transportation, industrial operations.

• Birdsong in parks

• Soft music from cafes

• Whispering conversations

Answer explanation

Sources of noise pollution in cities include traffic, construction, public transportation, and industrial operations, as they generate significant sound levels. In contrast, birdsong, soft music, and whispering are generally not considered noise pollution.

How does construction work contribute to noise pollution?

• Construction work generates loud sounds from machinery and transportation.

• Construction activities are silent.

• Construction work reduces noise levels.

• Construction sites use soundproof materials.

Answer explanation

Construction work generates loud sounds from machinery, tools, and transportation, significantly contributing to noise pollution. The other options incorrectly state that construction is silent or reduces noise.
