The key ingredients for a fire are heat, fuel and oxygen; take one of these away, and the flames are extinguished. Sound ...

A new acoustic levitation technique combines sound waves and electric charge to control multiple particles without physical ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...

Sonic Fire Tech, co-founded by aerospace engineer Geoff Bruder, has developed a system that uses infrasound – low-frequency sound waves below the threshold of human hearing ...

Determining the "loudest recorded sound" depends on how you define sound and on which measurements you choose to include.

For anyone facing cancer, the treatment options can feel brutally familiar: surgery, radiotherapy, chemotherapy, or a ...

Have you ever stepped outside on a frigid, quiet morning and heard sounds emanating from somewhere far away? It's not your ...

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

In a world buzzing with constant notifications, honking traffic, and daily stressors, the sound of waves offers a rare kind of sanctuary one that doesn’t just relax us, but actually resets the mind.
