It should be remembered that a barrier's performance can be severely reduced by temperature and wind gradients. Diffraction of a low frequency sound wave around a barrier. Note that the barrier does ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

In that paper, they discuss how they improved upon the original design to create a sound wave director that doesn’t cause the waves to lose energy as they travel. They also hope that this new ...

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 ...

Sound bath meditation is a unique mindfulness practice where participants are "bathed" in sound waves generated by various ...

Using an air vortex cannon to focus the sound waves from the bass reflex port, it ‘wiggles’ the flame out in a matter of seconds, as illustrated with a thermal camera. Compared to the much ...

Paimushin, V. N. Gazizullin, R. K. and Firsov, V. A. 2021. Experimental Method to Study the Sound Wave Interaction with a Thin-Walled Obstacle. Russian Aeronautics ...

When the sound waves are in the audible frequency range ... Allow each student to create this motion. After several repetitions, ask students to describe the rope motion. Ask them what kind ...

In fact, this new technology, which uses sound waves to enable digital payments, is slowly taking over the QR Code and NFC. Moreover, the technology works offline and supports both smartphones and ...

The ANC circuitry can cut unwanted noise by up to 45dB, enough to drown out voices and other mid-range frequencies like road noise or the sound of an aircraft’s engines. The EarFun Wave Pro ...
