Traffic noise stresses out frogs, but some have adapted

Frogs from noisy ponds near highways have altered stress and immune profiles compared to frogs from more quiet ponds—changes that reduce the negative effects of traffic noise on the amphibians. According to a new study, ...

Traffic noise may make birds age faster

Traffic noise may be associated with an increased rate of telomere loss in Zebra finches that have left the nest, according to a study published in Frontiers in Zoology. Telomeres are caps on the ends of chromosomes that ...

New greener and more efficient noise barriers

Researchers from Universidad Politécnica de Madrid (UPM) have developed a new vegetal and affordable noise barrier that significantly reduces both noise and the environmental and landscape impact.

Image: Evaluating the noise of future aircraft

As air traffic continues to surge in the U.S., neighbors who live near airports are complaining about the escalating noise. All the while, the demand for faster aircraft that travel at supersonic speeds is accelerating.

Birds sing shorter songs in response to traffic noise

Birds sing differently in response to traffic noise, which potentially affects their ability to attract mates and defend their territory, according to research published in Bioacoustics. The study found that a species of ...

Traffic noise reduces birds' response to alarm calls

Pollution can take many forms—including noise. Excess noise in the environment from sources such as traffic can have negative effects on animals that rely on sound to communicate and get information about their surroundings. ...

Songbirds sound the alarm about traffic noise

A new study led by Pacific University biologist Chris Templeton demonstrates that the alarm calls of songbirds are dramatically impaired by road traffic noise. Research by Templeton and colleagues has shown that signals critical ...
