The audible space : attuning the Orpheum in downtown Vancouver

Lo, Hiu Ying 11 1900 (has links)
We live in a culture that readily and pervasively privileges the eye over the ear. Architecture is regarded increasingly as picturesque images by spectators at distance and in isolation. Building starts to lose their plasticity and the close connection with the language and wisdom of the body. However, every touching experience of architecture is multi-sensory. Therefore, architecture involves seven realms of sensory experiences which interact and infuse each other in a continuum. The thesis attempts to locate at the aural realm as a theoretical departure point and to explore ways of counterbalancing the unconscious tendency concerning retinal dominance. It is intended to recapture the fading sensuality, tactility and embodied essence of architecture. The study of audible space corresponds to one specific perceptual phenomenon as the starting point. This is not intended slightly to undermine the reality mat in architectural synthesis, different sensory categories overlap. The experiment attempts to explore and reinstate the relationship between architecture and sound. It seeks to trace for the seams which tie together their adjacencies and to overhear the different mutations of visual sound and acoustical space. Concepts and methodologies that signify the role of sound in architectural and environmental design will be investigated. The project, hypothetically the extension of the Orpheum Theater, will serve as the vehicle for the petrifying the theoretical investigation.. The project attempts to discover room and potential for improvements between the conflicting forces. The locale's charm lies in its specificity and complexity as an enduring historical local musical precinct, a neighborhood of depopulated and deteriorating street life. The study at this particular locale also tries to scrutinize the architectural relationship between the old and new and the possible regain of eminent public activities in public spaces resultant from inappropriate urban planning strategy. / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate

A study of the acoustics of some Stockton auditoriums and rooms

Halik, Glen 01 January 1933 (has links) (PDF)
Though the original purpose of this thesis was to investigate the cause for criticisms of the acoustical properties of the College Auditorium, it has been enlarged to a study of other Stockton Auditoriums and rooms with the idea of securing a technique of acoustical analysis similar to that of acoustical engineers in the industries. It was planned at first to set up an oscillator and reverberation meter, but it was found that the apparatus expense would be quite prohibitive. This research was therefore confined to noise meter measurements and reverberation calculations, and includes much of architectural and engineering branches. However, this is a most practical and growing field for research and vocational opportunities. Unfortunately, the public is very ignorant of the benefits of acoustical treatment, and little can be done until is is educated in the subject. It was found that in actual practice the sound-pulse photography and ripple-tank studies of the reflections of sound waves and water waves in sectional models of auditoriums, as well as the use of reverberation meters, are not used by acoustical engineers (partly on account of expense, of course), for they need only apply the Sabine formula.

Desempenho acústico de templos e igrejas: subsídios à normalização / Acoustic performance evaluation of 3 churches, based on brazilian normalization

Moscati, Sandra Rachel 09 April 2013 (has links)
Este trabalho aborda a problemática da acústica de igrejas construídas a partir da segunda metade do século XX por meio da revisão bibliográfica e do estudo de caso de três igrejas na cidade de São Paulo. O objetivo da pesquisa é estudar o desempenho dos espaços sonoros internos e externos de três templos, escolhidos como amostras, com base na normalização brasileira vigente. Avaliaram-se por meio de medições acústicas o tempo de reverberação nas naves, o nível de ruído ambiente em frente às igrejas, o nível de ruído ambiente interno nas naves das igrejas, bem como o nível sonoro nas naves e em frente às igrejas durante os cultos religiosos. Com isso procurou-se realizar o levantamento dos problemas enfrentados pelas igrejas em relação à qualidade acústica nas naves e as possíveis interferências que causam à comunidade vizinha, quanto aos níveis sonoros emitidos. O equipamento de medição utilizado foi um analisador profissional de áudio. A arquitetura das igrejas e sua localização e implantação na cidade são determinantes para a qualidade acústica das naves e os níveis sonoros emitidos no entorno. A pesquisa revelou que o nível de ruído ambiente em frente às igrejas interfere na relação sinal/ruído nas naves e que a interferência do nível sonoro emitido no ambiente externo pelas igrejas durante o seu funcionamento depende da localização, condições de uso e sobretudo de suas condições arquitetônicas. Estas condições, quando mal resolvidas, decorrem de projetos em que os requisitos acústicos não foram observados ou deixados de lado durante a execução da obra. / This paper discusses the acoustic of churches built from the second half on of the twentieth century based on literature survey and the specific case study of three churches in the city of São Paulo. The objective of this research is to study the performance of internal and external sound in three temples, chosen as samples, based on the Brazilian standards in force. Measurements of the acoustic reverberation time in the aisle, the internal and external noise level of the environment, as well as in front of the churches during religious services were performed. Therefore, the survey of the problems faced by the churches regarding the acoustic quality in the aisles and possible interferences that it may cause to the surrounding community were evaluated. The measuring equipment used was a professional audio analyzer. The architecture of the churches, their implementation and location in the city are crucial to the acoustic quality of the aisles and sound levels emitted to the environment. The research revealed that the ambient noise level in front of the churches interferes in the signal / noise in aisles and the interference of sound emitted by the churches in the external environment during operation depends on the location, conditions of use and mainly its architectural conditions. These conditions, if poorly solved, result from projects in which the acoustic requirements were not observed or left out during the execution of the building
