Define noise pollution.
Noise pollution is harmful or annoying levels of noise in an environment, high enough to cause physiological stress and hearing loss.
In which unit is noise measured?
Noise is measured in decibels (dB).
The CDC and NIOSH state that regular noise above dB will damage a person's hearing.
The CDC and NIOSH state that regular noise above 85 dB will damage a person's hearing.
Name three sources of land-based noise pollution.
Land-based noise pollution comes from large urban areas, transport, construction, industry, night activities, and energy production.
True or False?
Sound travels a shorter distance in water than in air.
False.
Sound travels farther in water, so sonar sounds can travel hundreds of miles underwater.
Name three sources of aquatic noise pollution.
Aquatic noise pollution comes from ship propellers, offshore wind turbines, sonar, oil rigs and drilling, seismic surveys, and underwater construction.
How does noise pollution affect bats?
Noise pollution makes it difficult for bats to find their food.
How do birds respond to noise pollution when attracting mates?
Birds alter their singing pitch or sing at different times to attract mates.
How can loud noise lead to whales and dolphins becoming stranded?
Loud noise disrupts the echolocation of whales and dolphins, making it harder for them to navigate, which can lead to stranding.
How have whale pods responded to shipping and sonar noise?
Whale pods have changed their migratory routes to avoid shipping routes and sonar.
True or False?
Only sudden, very loud noises can cause permanent hearing loss.
False.
Long-term exposure to 100 dB or more, such as construction work, damages the inner ear and causes sensorineural hearing loss.
How can noise pollution cause stress and anxiety in people?
Noise pollution disturbs sleep, which leads to stress and anxiety.
In adults, noise pollution contributes to high blood pressure, disease, and impaired thought processing.
In adults, noise pollution contributes to high blood pressure, heart disease, and impaired thought processing.
Name two effects of noise pollution on child development.
Noise pollution can cause reading difficulties, speech delays, stress, and hyperactivity in children.
