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 ...

Using EV tires to counter traffic noise

Research shows that fitting tires with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.

Traffic noise reduces wild owls' foraging efficiency

A team of researchers has found that traffic noise reduces the foraging efficiency of wild owls by up to 89 percent. The team's world-first study examined how different levels of such noise affect the hunting efficiency of ...
