Architectural Acoustics: General Topics in Architectural Acoustics
The Audio Arts and Acoustics department at Columbia College in Chicago acquired a new building in 2003. The facility, a former bank, contained an old steel and concrete vault that was converted to a reverberation chamber. The acoustic properties of the space, including reverberation time, modal density, and early reflection maps were analyzed and compared to a computer model. Reflectograms were...
متن کاملArchitectural Acoustics, Noise, and INCE: Case Studies, Applications, and Integration of Architectural Acoustics in Building Information Modeling Three-Dimensional Modeling
Architecture and engineering firms use building information management BIM software applications increasingly in the design process; similarly, building owners create BIM models for existing facilities both for internal use and to aid future tenants, facilities managers, and designers in planning for maintenance programs, restoration, or renovation. As for other design and engineering disciplin...
متن کاملArchitectural Acoustics: New Frontiers in Room Acoustical Modeling I
Geometrical-acoustics GA modeling techniques assume that surfaces are large relative to the wavelengths of interest. For a given scenario, practitioners typically create a single 3D model with large, flat surfaces that satisfy the assumption over a broad range of frequencies. Such geometric approximations lead to errors in the spatial distribution of the simulated sound field because geometric ...
متن کاملArchitectural Acoustics: Current Topics in Measurement and Modeling
This study explores how paint affects the specific airflow resistance and visual appearance of nonwoven scrims used on acoustical ceiling tile. Nine different scrims are included. Each scrim is finished with two application rates of paint. The specific airflow resistance is measured by the ASTM C522 method. The painted samples are also scanned and the images processed by ImagePro software to ch...
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...
