After developing the largest subwoofers in the world, Geoffrey Heinzel explains how wave theory and room acoustics influence ...

Sound, when emitted by a source — whether a person or a piece of equipment — propagates in all directions through space, being reflected, absorbed, transmitted, or diffracted as it encounters surfaces ...

If you live in a noisy urban area, you're gonna love the sound of this. Researchers in Switzerland have developed a material that can dampen street noise while being four times thinner than ...

School of Mechanical Engineering, Xi’an Jiaotong University, Xi’an, China Due to the sub-wavelength structural characteristics and excellent wave regulation ability, metamaterials have important ...

The seafloor is an important boundary of the ocean sound field, and the acoustic property of seafloor sediment and its spatial distribution are important factors that affect the propagation and ...

Decentralization involves spreading control and decision-making across a network instead of a single authority. Unlike centralized systems, where one entity controls everything, decentralized ...

From echoing hallways and idling buses to boisterous band practices and shop classes, schools have long been known as noisy environments. Beyond the sounds produced by occupants and vehicles, ...
