All Flashcards
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).
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?
