What animals are being affected by noise pollution?
Whales and dolphins
are particularly impacted by noise pollution. These marine mammals rely on echolocation to communicate, navigate, feed, and find mates, and excess noise interferes with their ability to effectively echolocate.
What are three ways that noise pollution can negatively impact wildlife?
- hearing loss, resulting from noise levels of 85 db or greater;
- masking, which is the inability to hear important environmental cues and animal signals;
What are the effects of a noisy environment?
Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause
high blood pressure, heart disease, sleep disturbances, and stress
. These health problems can affect all age groups, especially children.
What level of sound is hazardous to human?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise
