An ever-growing body of scholarship on suburbia has largely focused on the adverse effects of suburbanization. However, suburbia was also a fruitful experimental field for modern architecture. Lina Bo Bardi built her ...

Public transit in the United States has depended increasingly on public subsidies since the inception of the federal mass transit assistance program in the early 1960s. The subsidies are associated with declining efficiency and labor productivity, as urban transit systems have overcapitalized, simplified fare structures, and extended service into sparse suburban markets. Despite these subsidies, transit has not proved successful in countering the effects on its market of increased automobile ownership and use and of decentralization of residences and places of employment.

Most room acoustic parameters are calculated with data from omni-directional or figure-of-eight microphones. Using an ambisonic microphone to record room impulse responses can open up several new areas of inquiry. It can yield much more information about the spatial characteristics of the sound field at the points of interest, including the diffuseness of the sound field and the directions of individual reflections. This method can also be used to produce high quality auralizations through ambisonic reproduction techniques. In this research, room impulse responses are measured in reverberant rooms used for music from stage and audience positions using a 16-channel, second-order ambisonic microphone and a dummy head. The results are analyzed using beamforming techniques and compared to those produced by acoustics models.

Utilizing the Bayesian inference framework, a model-based approach to the design of multilayer microperforated panel absorbers is developed. Capable of producing high acoustic absorption coefficients without fibrous porous materials, microperforated panel (MPP) absorbers are used in many situations where traditional materials do not suffice. By constructing composite sound absorbers comprising several MPP layers, the narrowband absorption of single MPPs can be increased to create wideband absorption. We develop a method for designing such multilayer MPP absorbers, which meet a user-specified absorption profile. By applying Bayesian model selection and parameter estimation to the design problem, the proposed method embodies Occam's razor, producing a design which meets the specified absorption requirements while minimizing the number of MPP layers used. The minimum number of layers required as well as the physical design parameters for each layer are returned automatically.
