In physics, sound energy is a form of energy that can be heard by living things. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.
In poetry cadence describes the rhythmic pacing of language to a resolution [2] and was a new idea in 1915 [3] used to describe the subtle rise and fall in the natural flow and pause of ordinary speech [4] where the strong and weak beats of speech fall into a natural order [5] restoring the audible quality to poetry as a spoken art. [6]
timbre or phonatory quality (quality of sound) Acoustically, these prosodic variables correspond closely to: Visualization of the prosody of a male voice saying "speech prosody": pitch in ribbon height, and periodic energy in ribbon width and darkness. Audio for the visualization above. fundamental frequency (measured in hertz, or cycles per ...
Sound waves may be viewed using parabolic mirrors and objects that produce sound. [9] The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy of ...
Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne . It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly, emitting a burst of light.
A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. [3] A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase. [4] A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives.

In historical linguistics, a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound (or, more generally, one phonetic feature value) by a different one (called phonetic change) or a more general change to the speech sounds that exist (phonological change), such as the merger of two sounds or the creation of a new sound.
