New theory of deep-ocean sound waves may aid tsunami detection

Acoustic-gravity waves are very long sound waves that cut through the deep ocean at the speed of sound. These lightning-quick currents can sweep up water, nutrients, salts, and any other particles in their wake, at any water ...

Scientists use light to probe acoustic tuning in gold nanodisks

In a study that could open doors for new applications of photonics from molecular sensing to wireless communications, Rice University scientists have discovered a new method to tune the light-induced vibrations of nanoparticles ...

New method provides direct SI traceability for sound pressure

Scientists at the National Physical Laboratory (NPL) - the UK's National Measurement Institute - have developed an optical method for remotely measuring sound pressure inside a fully anechoic chamber which is the first to ...

Sound bullets in water

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by ...
