Violin. Violin acoustics is an area of study within musical acoustics concerned with how the sound of a violin is created as the result of interactions between its many parts. These acoustic qualities are similar to those of other members of the violin family, such as the viola. The energy of a vibrating string is transmitted through the bridge ...
In music, timbre (/ ˈtæmbər, ˈtɪm -, ˈtæ̃ -/), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments. It also enables listeners to distinguish different ...
In modern academia, music theory is a subfield of musicology, the wider study of musical cultures and history. Music theory is often concerned with abstract musical aspects such as tuning and tonal systems, scales, consonance and dissonance, and rhythmic relationships. In addition, there is also a body of theory concerning practical aspects ...
Temporal envelope (ENV) and temporal fine structure (TFS) are changes in the amplitude and frequency of sound perceived by humans over time. These temporal changes are responsible for several aspects of auditory perception, including loudness, pitch and timbre perception and spatial hearing. Complex sounds such as speech or music are decomposed ...
Dynamic tonality delivers consonance by tempering the intervals between notes (into "pseudo-just tunings") and also tempering the intervals between partials (into "pseudo-harmonic timbres") through digital synthesis and/or processing. Aligning the notes of a pseudo-just tuning's notes and the partials of a pseudo-harmonic timbre (or vice versa ...
Body capacitance. Body capacitance is the physical property of a human body to act as a capacitor. [1] Like any other electrically conductive object, a human body can store electric charge if insulated. The actual amount of capacitance varies with the surroundings; it would be low when standing on top of a pole with nothing nearby, but high ...
During propagation, waves can be reflected, refracted, or attenuated by the medium. [5] The behavior of sound propagation is generally affected by three things: A complex relationship between the density and pressure of the medium. This relationship, affected by temperature, determines the speed of sound within the medium. Motion of the medium ...
The element hydrogen can be a form of stored energy. Hydrogen can produce electricity via a hydrogen fuel cell. At penetrations below 20% of the grid demand, renewables do not severely change the economics; but beyond about 20% of the total demand, [52] external storage becomes important. If these sources are used to make ionic hydrogen, they ...
