Black hole ringdowns could reveal signs of surrounding matter or new physics, giving scientists a new way to test gravity in ...

A new theoretical framework suggests that “hair” around black holes, representing surrounding matter or departures from the simplest general-relativistic models, could leave distinct signatures in ...

Brushing your retainer only does so much. The best ultrasonic retainer cleaners remove bacteria and debris —all without ...

Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful ...

Ultrasound-generated water microdroplets convert 56% of lignin waste into a potentially useful chemical in 20 minutes, ...

Some people are more sensitive to low-frequency noise, such as from ventilation systems, heat pumps, wind turbines and transformers. Why is that? The brain perceives low-frequency sounds in a ...

Engineers have been using piezoelectric crystals to generate acoustic ripples, surface acoustic waves (SAWs), that propagate along a material’s surface at gigahertz (GHz) frequencies for decades.

IT MAKES SENSE THAT BLUE WHALES, the largest animal on Earth, would also be among the loudest. Their calls can reach up to 188 decibels. If they traveled through the air, above the surface of the ...

Theories about the cause of the phenomenon The Hum abound, from acoustic pollution originating from human sources, to sounds that nature itself makes. Or that the ear itself produces the humming sound ...

Some people occasionally hear a low buzzing or humming sound that doesn't have a clear source. An estimated 2–4% of the world's population hear this. Scientists have been trying to figure out for ...
