The clever bit here is that each individual wave is inaudible on its own, so nobody hears anything unless they're at the ...

A groundbreaking sound technology could soon allow people to enjoy private listening experiences in public spaces without ...

Audible enclaves are small pockets of sound that are not disturbed by surrounding noise. They are produced by new ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

Researchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high ...

The researchers also tested a 40mm-diameter ping pong ball. By adjusting the magnitude and frequency of the water waves and changing whether some waves moved in step with others, the researchers ...

Study reveals Indian cities prioritize short-term heatwave responses, neglecting crucial long-term strategies.

Researchers at Massachusetts Institute of Technology (MIT) developed a terahertz amplifier-multiplier system that enables the ...

Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel. This effect is particularly strong for low-frequency ...
