The Brothertown Indian Nation has a centuries old heritage of group singing. Although this singing is an intangible heritage, these aural practices have left a tangible record through published music, as well as extensive personal correspondence and journal entries about the importance of singing in the political formation of the Tribe. One specific tangible artifact of Brothertown ancestral aural heritage–and focus of the acoustic research in this case study–is a house built in the 18th century by Andrew Curricomp, a Tunxis Indian.

In step with the construction of the house at Tunxis Sepus, Brothertown political formation also solidified in the 18th century between members of seven parent Tribes: various Native communities of Southern New England including Mohegan, Montauk, Narragansett, Niantic, Stonington (Pequot), Groton/Mashantucket (Pequot) and Farmington (Tunxis). Settler colonial pressure along the Northern Atlantic coast forced Brothertown Indian ancestors to leave various Indigenous towns and settlements to form into a body politic named Brotherton (Eeyamquittoowauconnuck). Nearly a century later, after multiple forced relocations, the Tribe–including many of Andrew Curricomp’s grand, and great grandchildren–were displaced again to the Midwest. Today, after nearly two more centuries, the Brothertown Indian Nation Community Center and museum are located in Fond du Lac, WI, just south of their original Midwestern settlement.

During contemporary trips back to visit parent tribes, members of the Brothertown Indian Nation have visited the Curricomp House at Tunxis Sepus.

However, by then it was known as the William Day Museum of Indian Artifacts. After the many relocations of Brothertown and their parent Tribes, the Curricomp house was purchased by a local landowner of European descent. The man’s groundskeeper, Bill Day, had a hobby of collecting stone lithic artifacts he would find during his gardening around the property. The land owner decided that having the Curricomp house would be a perfect home for his groundskeeper’s musings, as it was locally told that the house belonged to the last living Indian in the town. He had the Curricomp House moved to his property and named it for his gardener, the William Day Museum of Indian Artifacts.

The myth of the vanishing Indian is a commonly held trope in popular Western Culture. This colonial, or “last living Indian” history that dominates the archive, includes no real information about what Native communities actually used the space for, or where the descendants of Tunxis are now living. This acoustics case study intends for the living descendants of Tunxis Sepus to have sovereignty over the digital content created, as the house serves as a tangible cultural signifier of their intangible aural heritage.

Architectural acoustic heritage throughout Brothertown’s history of displacement is of value to their vibrant contemporary culture. Many of these tangible heritage sites have been made intangible to the Brothertown Community, as they are settler owned, demolished, or geographically inaccessible to the Brothertown diaspora–requiring creative solutions to make this heritage available. Both in-situ and web-based immersive interfaces are being designed to interact with the acoustic properties of the Curricomp house.

These interfaces use various music and speech source media that feature Brothertown aural Heritage. The acoustic simulations and auralizations created during this case study of the Curricomp House are tools: a means by which living descendants might hear one another in the difficult to access acoustic environments of their ancestors.

Acoustics should be a bigger piece in the building decarbonization puzzle

Popular version of 5aAA6 – Acoustic design trade-offs when reducing the carbon footprint of buildings
Presented at the 184 ASA Meeting
Read the abstract at https://doi.org/10.1121/10.0019111

The built environment is responsible for upwards of 40% of global carbon emissions and has sparked a change in how buildings are designed in an effort to mitigate the global climate crisis. Design goals to reduce the carbon footprint of a building directly affects acoustics, potentially causing unintended acoustical consequences. Yet building acoustics is often considered much later in the design of a building, if at all, resulting in missed opportunities to harmonize sustainable and acoustical design goals. Significant research is needed to further understand acoustic-decarbonization trade-offs, as preliminary results found that research at the intersection of building decarbonization and acoustic design lacks well behind other building disciplines (see Figure 1). Despite the lack of published work, several studies suggest that holistic building design solutions are possible, including the balancing the mass distribution of structures to achieve high sound insulation with less material, designing with natural materials that can reduce echoes, and selecting efficient mechanical systems that prevent unwanted noise.

Figure 1: Publication trends for five building disciplines and building decarbonization.

Building carbon emissions can be reduced by designing sustainable structural elements (including green roofs and mass timber structures) and reducing the material consumption of structures with high carbon emissions (such as concrete floors, as shown in Figure 2). Innovations in building and construction materials can further improve carbon emission savings, from reducing carbon emissions during material manufacturing and during building operation. Such strategies include the use of natural materials (including straw bales and compressed earth blocks), concrete mixes with lower cement proportions, and material optimization. Carbon emissions during the service life of a building can be reduced by selecting more efficient systems (such as multi-pane windows) and smart mechanical systems. These solutions also highlight the interdisciplinary nature of building design, as decisions in one discipline can directly influence acoustic performance.

Many of the strategies to reduce carbon emissions while balancing acoustic design goals have important trade-offs that should be further studied. Many sustainable structures can have unfavorable sound insulation due to a lack of mass. Many natural materials deteriorate at a faster rate than conventional materials. Lastly, the upfront cost and maintenance of efficient systems can make these solutions unattractive to building owners. This emphasizes the importance for further research at the intersection of building decarbonization and acoustics to better understand how to provide sustainable solutions that benefit the planet, building occupants, and building owners. Future decarbonization technologies will need to consider the acoustic implications to prevent post-construction retrofits and other design modifications. As the building industry continues to pursue aggressive sustainable targets, a holistic approach to building design is needed to truly provide a sustainable building.

Popular version of 1aCA1 – What would a Webchuck Chuck?
Presented at the 184 ASA Meeting
Read the abstract at https://doi.org/10.1121/10.0018058

Take all of computer music, advances in programming digital sound, the web and web browsers and create an enjoyable playground for sound exploration. That’s Webchuck. Webchuck is a new platform for real-time web-based music synthesis. What would it chuck? Primarily, musical and artistic projects in the form of webapps featuring real-time sound generation. For example, The Metered Tide video below is a composition for electric cellist and the tides of San Francisco Bay. A Webchuck webapp produces a backing track that plays in a mobile phone browser as shown in the second video

Video 1: The Metered Tide

The backing track plays a sonification of a century’s worth of sea level data collected at the location while the musician records the live session. Webchuck has fulfilled a long-sought promise for accessible music making and simplicity of experimentation.

Video 2: The Metered Tide with backing track

Example webapps from this new Webchuck critter are popping up rapidly and a growing body of musicians and students enjoy how they are able to produce music easily and on any system. New projects are fun to program and can be made to appear anywhere. Sharing work and adapting prior examples is a breeze. New webapps are created by programming in the Chuck musical programming language and can be extended with JavaScript for open-ended possibilities.

Webchuck is deeply rooted in the computer music field. Scientists and engineers enjoy the precision that comes with its parent language, Chuck, and the ease with which large-scale audio programs can be designed for real-time computation within the browser. Similar capabilities in the past have relied on special purpose apps requiring installation (often proprietary). Webchuck is open source, runs everywhere a browser does and newly-spawned webapps are available as freely-shared links. Like in any browser application, interactive graphics and interface objects (sliders, buttons, lists of items, etc.) can be included. Live coding is the most common way of using Webchuck, developing a program by hearing changes as they are made. Rapid prototyping in sound has been made possible by the Web Audio API browser standard and Webchuck combines this with Chuck’s ease of abstraction so that programmers can build up from low-level details to higer-level features.

Combining the expressive music programming power of Chuck with the ubiquity of web browsers is a game changer that researchers have observed in recent teaching experiences. What could a Webchuck chuck? Literally everything that has been done before in computer music and then some.

NASHVILLE, Tenn., Dec. 8, 2022 – During some of their most formative years, many children go to daycare centers outside their homes. While there, they require a supportive, healthy environment that includes meaningful speech and conversation. This hinges on the soundscape of the childcare center.

In his presentation at the 183rd Meeting of the Acoustical Society of America, Kenton Hummel of the University of Nebraska – Lincoln (UNL) will describe how soundscape research in daycares can improve child and provider outcomes and experiences. The presentation, “Applying unsupervised machine learning clustering techniques to early childcare soundscapes,” will take place on Dec. 8 at 11:25 a.m. Eastern U.S. in the Summit A room, as part of the meeting running Dec. 5-9 at the Grand Hyatt Nashville Hotel.

“Few studies have rigorously examined the indoor sound quality of childcare centers,” said Hummel. “The scarcity of research may deprive providers and engineers from providing the highest quality of care possible. This study aims to better understand the sound environment of childcare centers to pave the way toward better childcare.”

The goal of the research is to understand the relationship between noise and people. High noise levels and long periods of loud fluctuating sound can negatively impact children and staff by increasing the effort it takes to communicate. In contrast, a low background noise level allows for meaningful speech, which is essential for language, brain, cognitive, and social/emotional development.

Hummel is a member of the UNL Soundscape Lab led by Dr. Erica Ryherd. Their team collaborated with experts in engineering, sensing, early childcare, and health to monitor three daycare centers for 48-hour periods. They also asked staff to evaluate the sound in their workplace. From there, they used machine learning to characterize the acoustic environment and determine what factors influence the child and provider experience.

“Recent work in offices, hospitals, and schools has utilized machine learning to understand their respective environments in a way that goes beyond typical acoustic analyses,” said Hummel. “This work utilizes similar machine learning techniques to build and expand on that work.”

NASHVILLE, Tenn., Dec. 7, 2022 – If you’ve ever watched a movie where the audio is out of sync, it quickly becomes obvious that smooth, consistent sound is critical for movie enjoyment, especially during dialogue. Even slight discrepancies in background noise can disrupt a moviegoer’s experience.

At the upcoming meeting of the Acoustical Society of America, Jeffrey Reed of Taproot Audio Design will demonstrate the behind-the-scenes audio engineering required to recreate the acoustics of movie sets and locations. During the session, “Modern movie sound: reality and simulated reality,” Reed will share short clips of film to compare the original recording to the studio mixed product. The presentation will take place on Dec. 7 at 2:00 p.m. Eastern U.S. in the Summit A room at the Grand Hyatt Nashville Hotel, as part of ASA’s 183rd meeting running Dec. 5-9.

“Nearly everything you hear in a film has been added later or enhanced for effect. Consistency in background noise has a major impact, especially on dialogue in a movie,” said Reed. “Sometimes every single line of dialogue in a scene can have a different noise profile – the sound in the background varies and makes the sound choppy and disjointed. It’s up to us to smooth that out.”

Modern movie sound mixing uses techniques like impulse responses to reproduce dialogue and other sounds. These methods are crucial to align what moviegoers see and hear and keep them engaged in the story.

An impulse response is a short recording that allows audio engineers to recreate the acoustics of a room. Sonic qualities are recorded when a sound reverberates off the unique layout of a space. The impulse recording is then applied to the audio mix to digitally recreate the sound of that space and make the resulting scene of a film as believable as possible.

“There are a lot of moving parts to a film mix, from dialog, effects, and the ever-important musical score,” said Reed. “Each and every one is crucial to a film, and the joy of mixing is finding out what needs to be where at the right time. When it’s all said done though, dialog is king in a film mix and everything must carefully revolve around it.”

NASHVILLE, Tenn., Dec. 6, 2022 – Blackbird Studio in Nashville has an impressive client list that includes Carrie Underwood, Dolly Parton, Garth Brooks, and Johnny Cash, among many others. Part of its success may be because owners John and Martina McBride have focused on creating unique acoustic environments.

At the 183rd Meeting of the Acoustical Society of America, Dr. Peter D’Antonio of RPG Acoustical Systems and George Massenburg of McGill University will describe “The evolution of Blackbird Studio C,” a space designed to provide an accurate and immersive mixing and production environment. The presentation will take place on Dec. 6 at 5:20 p.m. Eastern U.S. in the Summit A room, following a presentation by D’Antonio on a new Non-cuboid Iterative Room Optimizer (NIRO) at 5:00 p.m. Both talks are part of the conference running Dec. 5- 9 at the Grand Hyatt Nashville Hotel.

Massenburg conceived the design and consulted with D’Antonio to collaborate and design the control room. After sound mixing in all known types of professional and experimental spaces, Massenburg wanted to create a unique, ambient anechoic space. Such a studio allows ambient sound to decay equally across different frequencies and is free from interfering reflections, making it sound like an indoor forest.

To achieve this and control all sound reflections in the room, the team covered the walls and ceiling with primitive root diffusers. Compared to a reflective surface, which bounces sound energy back in one direction, this technology causes sound energy to diffuse and radiate in many directions.

Musicians in the studio can hear and balance themselves without headphones or excessive amplification. Mixing engineers adapt quickly to the room and its ambience.

“In measuring the room, we noticed that the direct sound was followed immediately by reflections 30 decibels below the direct sound, which is what you find in an anechoic (echo-free) chamber,” said D’Antonio. “Yet the room did not exhibit the uncomfortable, ‘acoustically dead’ characteristics of an anechoic chamber. Quite the opposite! The room felt comfortably ambient, and hence we created the ambient-anechoic portmanteau: ambichoic.”

In the presentation, Massenburg and D’Antonio will also discuss user perceptions of the ambichoic studio and improvements to the room’s technology over time.
