All Flashcards
How can regulations and standards reduce noise pollution?
Governments can set limits on noise from construction, factories, and transport.
How do noise barriers help mitigate noise pollution?
Walls, fences, and noise-absorbing materials can block or reduce noise.
How does quieter technology contribute to noise reduction?
Electric vehicles and low-noise aircraft reduce noise levels.
How does public transportation help reduce noise pollution?
Buses and trains are generally quieter than individual cars.
How do green spaces mitigate noise pollution?
Trees and vegetation can absorb sound and reduce noise in urban areas.
Explain how noise regulations can mitigate noise pollution.
Regulations set limits on noise levels, reducing the impact of construction and other sources.
What is a decibel (dB)?
Unit to measure sound intensity; logarithmic scale.
What is the CDC?
Centers for Disease Control; focuses on public health.
What is NIOSH?
National Institute for Occupational Safety and Health; focuses on workplace safety.
What dB level can cause hearing damage?
85 dB
At what dB level does hearing damage begin?
85 dB
How does noise pollution affect children?
Decreased reading ability, hyperactivity, poor speech development, and stress.
How does noise pollution affect adults?
Increased blood pressure and difficulty concentrating.
How does noise pollution affect marine life?
Disrupts communication, causes hearing loss, alters migration.
Why is the decibel scale important to understand?
Small increases mean a big difference in loudness due to its logarithmic nature.
What are the effects of noise pollution on animals?
Hearing loss, stress, communication issues (echolocation, bird songs).
