The Sound of Waves (潮騒, Shiosai) is a 1954 novel by the Japanese author Yukio Mishima. It is a coming-of-age story of the protagonist Shinji and his romance with Hatsue, [1] the beautiful daughter of the wealthy ship owner Terukichi. For this book, Mishima was awarded the Shincho Prize from Shinchosha Publishing in 1954. It has been adapted ...
The frequency of a sound is defined as the number of repetitions of its waveform per second, and is measured in hertz; frequency is inversely proportional to wavelength (in a medium of uniform propagation velocity, such as sound in air). The wavelength of a sound is the distance between any two consecutive matching points on the waveform.
The first mathematical analysis of electromagnetic waves in a metal cylinder was performed by Lord Rayleigh in 1897. [6]: 8 For sound waves, Lord Rayleigh published a full mathematical analysis of propagation modes in his seminal work, "The Theory of Sound". [7]
A sound wave propagates through a material as a localized pressure change. Increasing the pressure of a gas or fluid increases its local temperature. The local speed of sound in a compressible material increases with temperature; as a result, the wave travels faster during the high pressure phase of the oscillation than during the lower pressure phase.
The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave.
This falls within the domain of physical acoustics. In fluids, sound propagates primarily as a pressure wave. In solids, mechanical waves can take many forms including longitudinal waves, transverse waves and surface waves. Acoustics looks first at the pressure levels and frequencies in the sound wave and how the wave interacts with the ...
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals.Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions.
Ring-diagram analysis, first introduced by Frank Hill, [30] is used to infer the speed and direction of horizontal flows below the solar surface by observing the Doppler shifts of ambient acoustic waves from power spectra of solar oscillations computed over patches of the solar surface (typically 15° × 15°). Thus, ring-diagram analysis is a ...
