Noise created by humans is pervasive in US protected areas

Protected areas in the United States, representing 14 percent of the land mass, provide places for respite, recreation, and natural resource conservation. However, noise pollution poses novel threats to these protected areas, ...

Quantum sound waves to open doors for more powerful sensors

For the last decade, scientists have been making giant leaps in their ability to build and control systems based on the bizarre rules of quantum mechanics, which describe the behavior of particles at the subatomic scale.

Reducing jet noise by controlling turbulence

Airlines and aircraft manufacturers are under increasing pressure to keep noise levels low for airport personnel and for people in surrounding neighborhoods.

How noise pollution is changing animal behaviour

Noise pollution, generally an unintended byproduct of urbanisation, transport and industry, is a key characteristic of human development and population growth. In some cases, it is produced intentionally, for example when ...

Electric cars are a hazard for blind people

Electric cars are good for the environment – but not for people who cannot see. They have problems detecting the silent vehicles. However, Norwegian research scientists are working on a solution.

Taking gravity from strength to strength

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but ...

Listeners may adapt to speaker-specific acoustics, study shows

Phonetic convergence, or phonetic imitation, is a form of speech production in which a talker's speech becomes similar to that of the person with whom they are speaking. In a recent article published in the journal Speech ...
