The study of underwater sound propagation modelling is crucial for advancing the understanding of acoustic behaviour in complex marine environments. Researchers use an array of numerical ...

The content discusses the fundamentals of acoustics, focusing on sound refraction, the anatomy of the ear, and how sound waves are perceived. It explains how sound travels through the ear, the ...

Ultrasound scans could soon be much more detailed, thanks to a novel material that can bend sound waves the “wrong” way. This property, known as negative refraction, means the material should bring ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

Noise barriers made from trees and other plants can provide a respite from unwanted noise pollution. When strategically placed by a roadway, in a backyard, or in a park, trees help reduce pesky noises ...

Editor's note: This article and the subsequent articles provide an introduction to Sound. It is excerpted from the book Audio in the 21st Century published by Intel Press. This excerpt is from Chapter ...

Many buildings serve purposes other than just giving us a roof over our head for shelter. Buildings such as hotels, offices, shops and medical facilities seek to offer inhabitants a sense of calmness, ...
