Damping of sound level with distance - decibel dB damping calculation calculator distance versus sound reduction free field loss - decrease drop fall in sound over distance versus dB sound at different distances microphone calculator distance drop ratio - ● Dampingof sound level vs. distance ● Distance law − Distance damping − Noise − SPL This is an approximation when the venue is a direct sound field or an anechoic chamber How does the sound decrease with change of distance?

How can we calculate the distance drop of the noise? Sound and noise propagation and the level damping.Sound attenuation (dissipation) with distance.How far can sound travel? Changing(decrease) of sound pressure level ΔL or sound pressurewith distance rin a free field (direct field), like in anechoic chambersConversion: Distance values → dB level changing - The 1/r law for sound pressureWith sound level ususally a level of a logarithmic ratio of sound pressure is meant.

Room acoustics and how to treat a room is a HUGE topic, this page only a scratches the surface of Room acoustics as there are so many different variables that effect sound.

FAQ on Room Acoustics and Treatment.

Only the main topics will be discussed here and should form a good starting point for learning what you want in this topic. This page concentrates mainly on improving the sound of a room, NOT sound proofing a room which is completly different. By sound proofing a room, your not only keep the sound out, you also keep sound in the room which can cause problems such as large RT60 and slap echos. Playing Card Polyhedral Construction. Above is a rhombicosidodecahedron, one of the Archimedean solids.

Playing Card Polyhedral Construction

It is "uniform on its vertices" , which means that every vertex is equivalent. At each vertex there is a pentagon, a square, a triangle, and another square. There are 60 vertices. Above is the dual to the rhombicosidodecahedron. It has 60 faces. How to build a paper geodesic dome model. 3-D Shapes.

High Performance Spaces: concert halls and opera houses that hit the right note. Henning Larsen Architects' new Harpa Concert & Conference Centre was conceived of as part of Reykjavik's harbour-development project; photo © Osbjørn Jacobsen Given the digital times in which we live, there's something reassuring about the fact that intelligent, relevant and inspiring performing-arts venues are still managing to be designed and built.

High Performance Spaces: concert halls and opera houses that hit the right note

In all their glorious materiality, they cock a cultural snook at the ever-growing disembodied consumption of online and downloaded music, dance and other art forms. Diorama. The word diorama /ˌdaɪəˈrɑːmə/ can either refer to a 19th-century mobile theatre device, or, in modern usage, a three-dimensional full-size or miniature model, sometimes enclosed in a glass showcase for a museum.


Dioramas are often built by hobbyists as part of related hobbies such as military vehicle modeling, miniature figure modeling, or aircraft modeling. [citation needed] Etymology[edit] The word "diorama" originated in 1823 as a type of picture-viewing device, from the French in 1822. The word literally means "through that which is seen", from the Greek di- "through" + orama "that which is seen, a sight". Mapping Your Room Through Sight and Sound. Max Neuhaus. TrueRTA Audio Spectrum Analyzer Software. TrueRTA's Quick Sweep employs a short digitally generated sweep (chirp) to measure the frequency response of electronic and acoustical systems.

The Bauhaus was initially supported and funded by the Weimar Government, but in 1925, the support was withdrawn and the School moved to Dessau.


In Dessau, the Bauhaus used many of its ‘modernist’ principles to design functional housing for the Government. In 1932, the Bauhaus moved to Berlin. Bauhaus was a front due to the numbers of Russian artists, including Kandinsky, who were a part of the Bauhaus. In 1933, in accordance with other acts to shut down all non-Aryan forms of artistic expression, the Bauhaus was closed.

This was the same year than many Jewish Professors and Directors were removed from University Positions and Government appointments in the arts, including the Opera and Symphony houses and Museums. Jean Arp. Kandinsky: Composition IV. Yuko Nishimura - Optical paper folding. Wednesday, 16 August 2006 The simple act of folding paper gives rise to sculptural forms that with particular lighting can produce architectural forms and geometric patterns of subtle contrast. I’m impressed with paper-folding’s extreme technological economy – requiring no specialist equipment other than a pair of functional hands. Yuko Nishimura produces complex optical paper works and space-structures with undulating folds and creases. Wassily Kandinsky. Excerpted from "Kandinsky: Compositions", by Magdalena Dabrowski Kandinsky and Music "The term "Composition" can imply a metaphor with music. Kandinsky was fascinated by music's emotional power. Because music expresses itself through sound and time, it allows the listener a freedom of imagination, interpretation, and emotional response that is not based on the literal or the descriptive, but rather on the abstract quality that painting, still dependent on representing the visible world, could not provide.

"Kandinsky's special understanding of the affinities between painting and music and his belief in the Gesamtkunstwerk, or the total work of art, came forth in his text "On Stage Composition," his play "Yellow Sound," and his portfolio of prose poems and prints Klange (Sounds, 1913).
