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 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
What is the effect of construction noise on human health?
Can cause permanent hearing damage in as little as 15 minutes at 100 dB.
How does noise pollution impact bird communication?
Birds might have to sing louder or at different times.
How does noise pollution impact bat communication?
Bats struggle to find food with echolocation.
How does noise pollution impact whale and dolphin communication?
Propellers and sonar can disrupt whale and dolphin communication, cause hearing loss, and even alter migration patterns.
