In 1991, scientists lowered 10 speakers into the water off of a remote Australian island in order to blast a monotonous 57 hertz tone from them for 10 days. Other researchers listened for the distant ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...

Measuring the speed of sound in matter created in heavy-ion collisions may be possible through analysis of fluctuations in the number of detected particles. Disclaimer: AAAS and EurekAlert! are not ...
