Isolation of Performance Halls from Ground Vibration
One of the inherent characteristics of transportation systems, especially steel wheel and rail systems, is that vehicles running on the roadway or trackway generate vibration which transmits through the ground into nearby buildings. As our urban areas build up or are redeveloped, it is frequently desired for a variety of reasons to place a concert hall or theater in a location which is in close...
متن کاملMultiplex cinema halls: Design and construction of six halls in the city of Mar del Plata
A shopping promenade that incorporates six cinema halls with capacities ranging from 150 to 310 locations has been built in the city of Mar del Plata, Argentina. The authors of this project were the architects Mariani, Pérez Maraviglia and Cañadas. The employer of the project was Florencio Aldrey Iglesias, who has a long and recognized trajectory both locally and nationally. The place chosen by...
متن کاملArchitectural Acoustics: Acoustics of Concert Halls II
Some high-resolution direction-of-arrival DOA estimation methods, such as the MUSIC method, have been developed based on vectorsensor array. However, these high-resolution methods suffer from serious drawbacks. Indeed, they are not able to estimate coherent signals and sensitive to calibration errors. Mainly to overcome these limitations and in particular to satisfy practical engineering applic...
متن کاملLecture Halls - Room Acoustics and Sound Reinforcement
This paper describes our experience with lecture halls with regard to the room acoustics, sound reinforcement and audio frequency induction loops for persons with hearing impairment. The optimum reverberation time and geometrical conditions for classrooms are well known. Recent research basically confirms this knowledge but indicates the need for shorter reverberation times. However, many exist...
متن کاملAn algebraic approach to Halls matching theorem
The purpose of this note is to present a proof of Hall's matching theorem (also called marriage theorem) which I have not encountered elsewhere in literature-what yet does not mean that it is necessarily new. We refer to Hall's theorem in the following form: Theorem 1 (Hall). Let n be a positive integer. Let be a bipartite graph whose set of vertices consists of n blue vertices B 1 ; B 2 Some n...
