New audio tech uses ultrasound to create isolated pockets of sound, enabling private listening without headphones.

Learn about localized audio spots, dubbed "audible enclaves," which can be placed with pinpoint accuracy while remaining ...

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a specific location.

Alphonse Pierre’s Off the Dome column covers songs, mixtapes, albums, scenes, snippets, movies, Meek Mill tweets, fashion trends—and anything else that catches his attention. This week, Alphonse meets ...

Late last year, a massive ocean swell caused by a low pressure system in the North Pacific generated waves up to 20 meters ...

For the first time, MIT scientists have successfully imaged how heat actually travels in a wave, known as a “second sound,” through this exotic fluid. Understanding this dynamic could help ...

It describes how sound waves are created through vibrations, how they can be visualized using electrical devices, and how different frequencies affect pitch. The film demonstrates the properties ...

A singing balloon experiment is a great way to learn how sound works. If you put a small coin inside a balloon and spin it, the coin spins around the balloon, making the balloon vibrate very quickly.

The “Helmholtz resonator” concept explains the frequencies of sound produced by clapping the hands together in different configurations.

Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher supply voltages, implement it using discrete ...
