Using Sound Waves to Put Out Fire: Story of Two George Mason University Students

New audio tech could let you listen privately without headphones | With acoustic metasurfaces, researchers bend sound waves to their will

Swirling sound waves used to rip apart kidney stones | Scientists have devised a method of non-invasively tearing the objects apart, using what are known as "acoustic vortex beams."

One-way street for sound waves

Handheld diagnostic that can isolate biomarkers for different diseases using sound waves, from a single drop of blood, in around an hour.

Researchers develop method to make sound waves travel in one direction only | The research has applications in various fields, including radar technology and signal routing

Physicists Generated Sound Waves That Travel In One Direction Only

Physicists generated sound waves that travel in one direction only

Spiderwebs can pick up vibrations in air flow caused by sound waves, and researchers say microphones designed this way could become more sensitive and compact.

Sound waves cut cold brew coffee-making time from 24 hours to 3 mins | Researchers have developed an ultrasonic machine to speed up the cold brew of ground coffee beans.

How scientists are using sound waves to hack the brain

Researchers developed a battery-free sensor that reacts to sound waves, producing vibrational energy to power an electronic device | The novel sensor would not only reduce battery waste but could also power medical devices like cochlear implants or monitor buildings for faults.

Revolutionary X-ray microscope unveils sound waves deep within crystals. Scientists developed a groundbreaking technology that allows them to see sound waves and microscopic defects inside crystals, promising insights that connect ultrafast atomic motion to large-scale macroscopic behaviors.
