Planephones
Planephones, or ''planofoni'', represent an innovative sound art creation. They are vibrating systems based on wood panels (or other materials) and different forms. Planephones diffuse the sound according to specifications which depend on the structure of the material, on the geometry of the design, on the orientation and curvature of the surfaces, and on the plastic volumes occupied. Planephones differ from conventional sound diffusion systems in that the sound acquires the timbral quality of the material employed and, in addition, by diffusing the sound homogeneously along the surface, permits designing the acoustic space. according to the architectural space. Planephones were conceived by composer Michelangelo Lupone, as art installations Installation art is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed-Drum
The Feed-Drum is an imperial bass drum with a system of electronic conditioning of the skin conceived by composer Michelangelo Lupone and coproduced between CRM - Centro Ricerche Musicali, Rome and Istituto Gramma in L'Aquila. Through the principle of feed-back, the signal produced by the excitation of the skin returns to the skin in the form of acoustic pressure. The result is an infinitely sustained sound. The system controls the damping of the movement of the skin, and therefore the decay rate of the sound, and permits isolation of high frequency modes by the combined action of nodes present on the skin and the amount of feed-back input energy. The design on the skin surface is a simplified map of the oscillatory modes based on the Bessel functions. The map was limited to 13 diameters and 8 nodal circles, the latter divided into even semicircles (to the left) and odd semicircles (to the right). See also Skin-Act.

Sound Art
Sound art is an artistic activity in which sound is utilized as a primary medium or material. Like many genres of contemporary art, sound art may be interdisciplinary in nature, or be used in hybrid forms. According to Brandon LaBelle, sound art as a practice "harnesses, describes, analyzes, performs, and interrogates the condition of sound and the process by which it operates." In Western art, early examples include Luigi Russolo's '' Intonarumori'' or noise intoners (1913), and subsequent experiments by dadaists, surrealists, the Situationist International, and in Fluxus events and other Happenings. Because of the diversity of sound art, there is often debate about whether sound art falls within the domains of visual art or experimental music, or both. Other artistic lineages from which sound art emerges are conceptual art, minimalism, site-specific art, sound poetry, electro-acoustic music, spoken word, avant-garde poetry, sound scenography, and experimental thea ...

Art Installations
Installation art is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often called public art, land art or art intervention; however, the boundaries between these terms overlap. History Installation art can be either temporary or permanent. Installation artworks have been constructed in exhibition spaces such as museums and galleries, as well as public and private spaces. The genre incorporates a broad range of everyday and natural materials, which are often chosen for their " evocative" qualities, as well as new media such as video, sound, performance, immersive virtual reality and the internet. Many installations are site-specific in that they are designed to exist only in the space for which they were created, appealing to qualities evident in a three-dimensional immersive medium. Artistic collectives such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holophones
A parabolic loudspeaker is a loudspeaker which seeks to focus its sound in coherent plane waves either by reflecting sound output from a speaker driver to a parabolic reflector aimed at the target audience, or by arraying drivers on a parabolic surface. The resulting beam of sound travels farther, with less dissipation in air, than horn loudspeakers, and can be more focused than line array loudspeakers allowing sound to be sent to isolated audience targets.Borgerson, Bruce"Technology Showcase: Focused Loudspeaker Systems."AVInstall, November 1, 2005. Retrieved on August 25, 2009. The parabolic loudspeaker has been used for such diverse purposes as directing sound at faraway targets in performing arts centers and stadia, for industrial testing, for intimate listening at museum exhibits, and as a sonic weapon. Technology A parabolic loudspeaker can send sound farther than traditional loudspeaker designs. The focused waves of a parabolic loudspeaker tend to dissipate in air at about 3 ...
