Fighting tuberculosis with light and sound

A UK-wide research team, led by the Schools of Physics and Astronomy and Medicine at the University of St Andrews, has developed an innovative way to monitor the reaction of living bacteria to antibiotics using lasers and ...

Using AI to map marine environments

Sonar is commonly used to map the ocean floor, and seabed composition (e.g. mud, clay or rock) affects the way the sound is reflected back. Salinity, depth and water temperature also affect how sound waves are propagated ...

How COVID-19 shutdowns are allowing us to hear more of nature

On a Friday, in late February, during rush-hour in Truro, N.S., I recorded 80 seconds of noise dynamics at a four-way intersection. I returned on April 3 after the COVID-19 restrictions sent people in Canada indoors. More ...

Bats can use 'vocal learning' to change their tune

Humans learn to speak by mimicking speech sounds. Are there other mammals who can learn sounds by imitation? In an experimental study, researchers from the Max Planck Institute for Psycholinguistics in Nijmegen and the Ludwig ...

Seeking 'soundwaves' in the superfluid order parameter

A Swinburne University of Technology study published this week examines the propagation of energy as sound waves in a quantum gas, revealing for the first time strong variations in the nature of the sound wave as a function ...

Sound

Sound is a travelling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
