A sounding board, also known as a tester and abat-voix is a structure placed above and sometimes also behind a pulpit A pulpit is a raised stand for preachers in a Christian church. The origin of the word is the Latin ''pulpitum'' (platform or staging). The traditional pulpit is raised well above the surrounding floor for audibility and visibility, accesse ... or other speaking platform that helps to project the sound of the speaker. It is usually made of wood. The structure may be specially shaped to assist the projection, for example, being formed as a parabolic reflector. In the typical setting of a church building, the sounding board may be ornately carved or constructed. The term "abat-voix," from the French word for the same thing (''abattre'' (“to beat down”) + ''voix'' (“voice”)), is also used in English. The term “sounding board” is also used figuratively to describe a person who listens to a speech or proposal in order that the speaker may rehears ...

Pulpit
A pulpit is a raised stand for preachers in a Christian church. The origin of the word is the Latin ''pulpitum'' (platform or staging). The traditional pulpit is raised well above the surrounding floor for audibility and visibility, accessed by steps, with sides coming to about waist height. From the late Middle Ages, late medieval period onwards, pulpits have often had a canopy known as the sounding board, ''tester'' or ''abat-voix'' above and sometimes also behind the speaker, normally in wood. Though sometimes highly decorated, this is not purely decorative, but can have a useful acoustic effect in projecting the preacher's voice to the Church (congregation), congregation below, especially prior to the invention of modern audio equipment. Most pulpits have one or more book-stands for the preacher to rest his bible, notes or texts upon. The pulpit is generally reserved for clergy. This is mandated in the regulations of the Catholic Church, and several others (though not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Parabolic Reflector
A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a Mirror, reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. The parabolic reflector transforms an incoming plane wave travelling along the axis into a spherical wave converging toward the focus. Conversely, a spherical wave generated by a point source placed in the focus (optics), focus is reflected into a plane wave propagating as a collimated beam along the axis. Parabolic reflectors are used to collect energy from a distant source (for example sound waves or incoming star light). Since the principles of Specular reflection, reflection are reversible, parabolic reflectors can also be used to collimate radiation from an isotropic source into a parallel beam (optics), beam. In optics, parabolic mirrors are used to gather light in reflecting telescop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Baldachin

It had its beginnings as a cloth canopy, but in other cases it is a sturdy, permanent Architecture, architectural feature, particularly over Altar, high altars in cathedrals, where such a structure is more correctly called a Ciborium (architecture), ciborium when it is sufficiently architectural in form. Baldachins are often supported on columns, especially when they are disconnected from an enclosing wall. A cloth of honour or cloth of estate is a simpler cloth hanging vertically behind the throne, usually continuing to form a canopy. It can also be used for similar canopies in interior design, for example above beds, and for processional canopies used in formal state ceremonies such as coronations, held up by four or more men with poles attached to the corners of the cloth. "''Baldachin''" was originally a luxurious type of cloth from Baghdad, from which name the word is ultimat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chhatri
''Chhatri'' are semi-open, elevated, dome-shaped pavilions used as an element in Indo-Islamic architecture and Indian architecture. They are most commonly square, octagonal, and round. Originating as a canopy above tombs, they largely serve as decorative elements as opposed to functional elements. The earliest examples of chhatri being used in the Indian Subcontinent were found in the Shrine of Ibrahim in Bhadreswar, constructed between 1159 and 1175 AD. Chhatri are found particularly within Mughal architecture. The most notable surviving examples today are to be found at Humayun's Tomb in Delhi and the Taj Mahal in Agra. The Berar Sultanate in the Deccan added chhatris on buildings in its various capitals. Chhatri have also been used in Rajasthan and other parts of the Indian Subcontinent by both Muslim and Hindu rulers. They are primarily used to manipulate skylines, an important aspect of Rajasthani architecture. For instance, they may be added to building roofs, ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Church Architecture
Church architecture refers to the architecture of Christian buildings, such as Church (building), churches, chapels, convents, and seminaries. It has evolved over the two thousand years of the Christian religion, partly by innovation and partly by borrowing other architectural styles as well as responding to changing beliefs, practices and local traditions. From the Early Christianity to the present, the most significant objects of transformation for Christian architecture and design were the great churches of Byzantium, the Romanesque architecture, Romanesque abbey churches, Gothic architecture, Gothic cathedrals and Renaissance architecture, Renaissance basilicas with its emphasis on harmony. These large, often ornate and architecturally prestigious buildings were dominant features of the towns and countryside in which they stood.
