The main purpose of hearing aid domes is to direct the amplified sound from the hearing device directly into the ear canal. Depending on what type of behind-the-ear hearing aid you have, the sound amplification starts with the small processor behind the ear as soon as the sound waves are received through the microphone.

What exactly is a "dome"?
The Washington Post described it like so: “When the summer sun warms air above the ground or ocean, that air can then rush up into the atmosphere to form a mountain — or dome — of slow-moving hot air under higher pressure that blocks new weather systems from moving in. Basically, it’s a mass of warm air that’s stuck over a certain area.”

What is a dome in architecture?
Architecture portal. v. t. e. A dome (from Latin: domus) is an architectural element similar to the hollow upper half of a sphere; there is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome.
How does a dome work?
The thrusts generated by a dome are directly proportional to the weight of its materials. Grounded hemispherical domes generate significant horizontal thrusts at their haunches.
Why are voussoir domes thinner than hemispherical domes?
Because voussoir domes have lateral support, they can be made much thinner than corresponding arches of the same span. For example, a hemispherical dome can be 2.5 times thinner than a semicircular arch, and a dome with the profile of an equilateral arch can be thinner still.
How are paraboloid domes formed?
A paraboloid dome is a surface formed by the rotation around a vertical axis of a sector of a parabola. Like other "rotational domes" formed by the rotation of a curve around a vertical axis, paraboloid domes have circular bases and horizontal sections and are a type of "circular dome" for that reason.
How are ellipsoidal domes formed?
The ellipsoidal dome is a surface formed by the rotation around a vertical axis of a semi-ellipse. Like other "rotational domes" formed by the rotation of a curve around a vertical axis, ellipsoidal domes have circular bases and horizontal sections and are a type of "circular dome" for that reason.
Where are bulbous domes found?
An onion dome is a greater than hemispherical dome with a pointed top in an ogee profile. They are found in the Near East, Middle East, Persia, and India and may not have had a single point of origin. Their appearance in northern Russian architecture predates the Tatar occupation of Russia and so is not easily explained as the result of that influence. They became popular in the second half of the 15th century in the Low Countries of Northern Europe, possibly inspired by the finials of minarets in Egypt and Syria, and developed in the 16th and 17th centuries in the Netherlands before spreading to Germany, becoming a popular element of the baroque architecture of Central Europe. German bulbous domes were also influenced by Russian and Eastern European domes. The examples found in various European architectural styles are typically wooden. Examples include Kazan Church in Kolomenskoye and the Brighton Pavilion by John Nash. In Islamic architecture, they are typically made of masonry, rather than timber, with the thick and heavy bulging portion serving to buttress against the tendency of masonry domes to spread at their bases. The Taj Mahal is a famous example.
What is the top of a dome called?
The top of a dome is the "crown". The inner side of a dome is called the "intrados" and the outer side is called the "extrados". As with arches, the "springing" of a dome is the base level from which the dome rises and the "haunch" is the part that lies roughly halfway between the base and the top.
What is a dome in architecture?
Dome, in architecture, hemispherical structure evolved from the arch, usually forming a ceiling or roof. Domes first appeared as solid mounds and in techniques adaptable only to the smallest buildings, such as round huts and tombs in the ancient Middle East, India, and the Mediterranean. The Romans introduced the large-scale masonry hemisphere.
How many piers did the apexes of the dome have?
Their apexes rested on the four piers, to which they conducted the forces of the dome; their sides joined to form arches over openings in the four faces of the cube; and their bases met in a complete circle to form the dome foundation.
What is a dome?
Vocabulary. A dome is a curved formation or structure. It is shaped like half of a sphere. Imagine cutting an orange in half, and placing it cut-side-down on a table. This is the shape of a dome, although most domes in nature are not perfectly rounded. Some natural domes develop when magma from deep within the Earth pushes up surface rock layers.
How do domes form?
Some natural domes develop when magma from deep within the Earth pushes up surface rock layers. This type of geologic dome can form as magma intrudes between two layers of sedimentary rock. The magma creates a dome or triangle shape as it pushes the other layers apart.
How are geodesic domes made?
Geodesic dome s are created using a complex series of triangles. Geodesic domes are an efficient architectural design; they are stronger, lighter, and quicker to construct than more traditional buildings. They also enclose a large amount of space with minimal materials, labor, and energy.
Why are salt domes important?
Salt domes are important sites for industry. Salt is a valuable mineral used in the production of plastic s , pesticide s , preservative s, and fire extinguishing equipment. The salt mines near Avery Island and in the Zagros Mountains are hundreds of years old. Salt domes are also important for the petroleum industry.
What are the most famous domes?
Architectural Domes. Domes are one of the most familiar features in architecture, or the structure of buildings. One of the most famous domes is the Taj Mahal , a mausoleum in Agra, India. Domes are frequently used for government buildings, such as the U.S. Capitol in Washington, D.C.
Where is the Dome of the Rock?
They are also used in religious architecture, such as the Dome of the Rock, an Islamic shrine in Jerusalem, Israel; and the Florence Cathedral, a Catholic church in Florence, Italy. (The Florence Cathedral is even nicknamed the Duomo or Brunelleschis Dome, after its architect, Filippo Brunelleschi .)
Where is the salt dome?
One of the most famous salt domes is Avery Island, in the U.S. state of Louisiana. Avery Island is a salt dome surrounded by low-lying swamp s of the Mississippi River delta.
Why are domes used in architecture?
Before then people of many different religions — including the pagans of Rome, Christians, Hindus, and Muslims — used the dome to express similar types of spiritual symbolism.

When was the Pantheon built?
One of the most ancient and well preserved domes is that of the Pantheon in Rome. It was built in the 2nd century and proved to be a model for all other domes after it. The building was originally built as a Roman temple dedicated to all the gods, as its Greek name indicates.
What is a dome in architecture?
In its basic form, a dome is a hollowed structure in the form of a semi-sphere.
How efficient are domes?
This is because they are self-supporting, stabilized gravity acting upon their weight to keep them compressed into shape. The weight of classic domes produces both a downward and an outward force. The down thrust should be moved to the structures, whilst the outside thrust should be withstood to keep the dome walls from collapsing. The necessary resistance is supplied by the sheer mass of the walls, buttresses, or by a stress reliever such as a border ring, chain, or network of cables.
Why do domes cost less?
That raises the cost. What lowers the cost is the material. Because domes are such a smart design, they take less material than more traditional buildings . Of course, the cost of material will depend on what you choose to use and how large your building will be.
What materials are domes made of?
Domes can be built from a range of materials, from standard masonry and concrete to cast steel, lumber, and iron . Your choice of product will depend on how large you want your dome to be and you want it to look like inside and out.
What is dome roofing?
Known as “the kings of all roofing,” domes cover a few of our crucial structures. Domes are entirely curved buildings—having no corners nor angles–and they confine a massive quantity of area without the aid of any columns. Regardless of their thin nature, domes are a few of the most structurally sound structures out there today.
What is the most well known dome in the world?
Among the most well-known domes on the planet is Disney’s Epcot Center. A brand-new era of dome structures, geared up with retractable roofing, (the Toronto SkyDome, for example), is becoming a popular option for sports arenas worldwide.
Why is a dome more expensive than a roof?
Not as Expensive as You Might Think. Building a dome may cost more than other types of roofs simply because it’s a unique type of structure. Not all contractors or experienced with or comfortable erecting this type of building, so you’ll have to employ more of a specialist. That raises the cost.
Overview
A dome (from Latin domus) is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.
Etymology
The English word "dome" ultimately derives from the ancient Greek and Latin domus ("house"), which, up through the Renaissance, labeled a revered house, such as a Domus Dei, or "House of God", regardless of the shape of its roof. This is reflected in the uses of the Italian word duomo, the German/Icelandic/Danish word dom ("cathedral"), and the English word dome as late as 1656, when it meant a "Town-House, Guild-Hall, State-House, and Meeting-House in a city." The Frenc…
Definitions
Across the ancient world, curved-roof structures that would today be called domes had a number of different names reflecting a variety of shapes, traditions, and symbolic associations. The shapes were derived from traditions of pre-historic shelters made from various impermanent pliable materials and were only later reproduced as vaulting in more durable materials. The hemisph…
Elements
The word "cupola" is another word for "dome", and is usually used for a small dome upon a roof or turret. "Cupola" has also been used to describe the inner side of a dome. The top of a dome is the "crown". The inner side of a dome is called the "intrados" and the outer side is called the "extrados". As with arches, the "springing" of a dome is the base level from which the dome rises and the "haunch" is the part that lies roughly halfway between the base and the top. Domes can …
Materials
The earliest domes in the Middle East were built with mud-brick and, eventually, with baked brick and stone. Domes of wood allowed for wide spans due to the relatively light and flexible nature of the material and were the normal method for domed churches by the 7th century, although most domes were built with the other less flexible materials. Wooden domes were protected from the weather by roofing, such as copper or lead sheeting. Domes of cut stone were more expensive a…
Shapes and internal forces
A masonry dome produces thrusts downward and outward. They are thought of in terms of two kinds of forces at right angles from one another: meridional forces (like the meridians, or lines of longitude, on a globe) are compressive only, and increase towards the base, while hoop forces (like the lines of latitude on a globe) are in compression at the top and tension at the base, with the transition in a hemispherical dome occurring at an angle of 51.8 degrees from the top. The thrus…
Symbolism
According to E. Baldwin Smith, from the late Stone Age the dome-shaped tomb was used as a reproduction of the ancestral, god-given shelter made permanent as a venerated home of the dead. The instinctive desire to do this resulted in widespread domical mortuary traditions across the ancient world, from the stupas of India to the tholos tombs of Iberia. By Hellenistic and Roman times, the domical tholos had become the customary cemetery symbol.
Acoustics
Because domes are concave from below, they can reflect sound and create echoes. A dome may have a "whispering gallery" at its base that at certain places transmits distinct sound to other distant places in the gallery. The half-domes over the apses of Byzantine churches helped to project the chants of the clergy. Although this can complement music, it may make speech less intelligible, leading Francesco Giorgi in 1535 to recommend vaulted ceilings for the choir areas o…
