    Abstract: Raytracing is a simple but powerful tool in acoustics consulting because of its ability to geometrically approximate wave behavior across a large portion of the audible spectrum. The use of this method requires an understanding of the frequency-dependent interaction between sound waves and geometry, which is a wave-specific behavior that any use of ray-based approximations must consider. The limitations of these approximations may necessitate geometric modifications in a model to render credible results, or may even dictate raytracing is inappropriate for a given application. Ray-based analysis can be used for applications with a wide range of complexity, from hand-traced sketches to computational simulation for full-scale rooms. Common applications include analysis of reflector coverage, design of room shape and major room components, and impulse response simulation for analysis and auralization. Due to their efficiency and simplicity, ray methods remain indispensable in architectural acoustic analysis.

    Abstract: Flutter is generally considered an acoustical defect – the timbral distortions and rhythmic nature can be distracting, annoying, or downright disruptive. The paper recontextualizes flutter as a compositional tool for sound art, particularly when the flutter of existing rooms is used for site-specific installations. Due to the global COVID-19 pandemic, the artist was unable to travel, allowing us to visit the site and take several room impulse responses. The measured spaces were parallelpiped, sound reflective, and fluttery. To give the artist creative flexibility, we simulated the rooms for an extended range of source and receiver locations informed by the in-situ measurements. This paper will discuss our calibration and modeling techniques to simulate flutter and reverberation coloration in real rooms, which is non-trivial for image source methods or ray-based software.

    Abstract: Communication is at the heart of everything we do as consultants. We are constantly striving for new and better ways to guide our clients to make informed decisions. In situ auralizations of major pieces of future mechanical / electrical equipment allows major stakeholders and decision makers to get an aural sense for various equipment configurations, enclosure types, and barrier wall buildups prior to installation. After the auralization, board members and homeowners from past projects had a richer understanding of the anticipated experience at the property line and nearby classroom spaces when compared to reviewing graphs and charts alone. We will explore the value of, and challenges with, this in situ auralization method, as well as some future improvements to further validate the process through the lens of two past projects—New Trier High School and Lake Bluff Middle School in Illinois.

    Abstract: The recently completed Lindemann Performing Arts Center on the Brown University campus is an exploration in all things flexible. To satisfy the programmatic needs of Brown Arts Initiative, the primary user of this new building, who needed five rooms but only got one, the Main Hall redefined the concept of multiuse hall. All sixsurfaces that define the major acoustically supportive surfaces (ceiling elements, walls, and floors) move to manipulate the otherwise beautifully simple architectural concept into five room configurations—Orchestra, Recital, End Stage Theatre, Experimental Media, and large Flat Floor. A mix of manual and motorized curtains and banners adds still more flexibility. As the paint still dries on the building, this paper will investigate the acoustic challenges, happy accidents, and areas where we might have done with less (or more) in a building that is sometimes heavy handed and sometimes a light touch. The paper will cover topics such as glass as a major reflecting surface, wall buildups that break rules of thumb to produce warm acoustic responses, use of variable acoustic solutions, and ensemble to audience size ratios that challenge conventional wisdom.
