Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can ...

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...

IT is a well-known fact that the propagation of sound in the atmosphere is greatly affected by temperature and wind conditions, yet quantitative data on the actual field of intensity from a sound ...

Ten years ago, researchers succeeded in suppressing sound wave propagation in the backward direction; however, this also attenuated the waves traveling forwards. A team of researchers at ETH ...

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...

Acousto-optics is a versatile technology that allows users to precisely and rapidly control the wavelength, amplitude and propagation ... to the frequency of the sound wave. This grating can ...

The effects described above can be implemented by cancelling the forward characteristics of the linear loudspeaker array, and then overlaying the desired sound-wave propagation characteristics.

Speed\((v)\) is in metres per second \(m\,s^{-1}\), distance \((d)\) in metres \((m)\) and time\( (t)\) in seconds \((s)\). Measuring the time taken for a sound wave ...
