All Flashcards
How can regulations and standards mitigate noise pollution?
Governments can set limits on noise from construction, factories, and transport.
How can noise barriers mitigate noise pollution?
Walls, fences, and noise-absorbing materials can block or reduce noise.
How can quieter technology mitigate noise pollution?
Electric vehicles and low-noise aircraft reduce noise emissions.
How can public transportation mitigate noise pollution?
Buses and trains are generally quieter than individual cars.
How can green spaces mitigate noise pollution?
Trees and vegetation can absorb sound and reduce noise in urban areas.
What are the effects of noise pollution on wildlife?
Hearing loss, stress, communication issues, altered migration patterns.
What are the effects of long-term exposure to noise pollution?
Can lead to decreased reading ability, hyperactivity, poor speech development, and stress in children; increased blood pressure and difficulty concentrating in adults.
What is the effect of propellers and sonar on marine life?
Disrupts whale and dolphin communication, causes hearing loss, and can alter migration patterns.
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).
