They are the most commonly used types of sound in multimedia productions today. For example, if we plot the amplitude over a period of time for both the sound generated by speech and by a piece of music, we would find that the shape of the two waves is quite different. The requirements...
In subject area:Computer Science Audio compression refers to the process of reducing the size of audio files by applying techniques such as sampling and quantization. It involves modeling sound as a collection of sine and cosine waves and can be applied in speech and music compression. ...

Wavelet analysis and interpretation of gravity data in Sichuan-Yunnan region, China The Bouguer gravity anomaly data of Sichuan-Yunnan region and its vicinity were analyzed with wavelet transformation method. In the process, complete ortho... L Hai,CY Wang - 《Earthquake Science》 被引量: 70发表...
A part of the shock-waves science and technology has stimulated the research field of "Materials Dynamics" which needs some technological evolution for the diagnostics of ultra fast phenomena and some conceptual evolution for the hierarchy of the material domain dependent on sound speed. This article...
Solitons are nonlinear waves present in diverse physical systems including plasmas, water surfaces and optics. In silicon, the presence of two photon absorption and accompanying free carriers strongly perturb the canonical dynamics of optical solitons. Here we report the first experimental demonstration of...
15.2 Sound waves and boundaries Like other waves, sound waves can be reflected by surfaces and refracted as they pass from one material to another. Sound waves reflect from hard surfaces. Ex. Echo 15.3 Music The pitch of a sound is how high or low we hear its frequen...

This book presents a set of basic understandings of the behavior and response of solids to propagating shock waves. The propagation of shock waves in a solid body is accompanied by large compressions, decompression, and shear. Thus, the shear strength of solids and any inelastic response due to...
