One family. One laboratory. Three generations of acoustical science.

The Sabines at Riverbank is now available in full. Download the complete book as a PDF today.

Written by John W. Kopec and published by the Acoustical Society of America in 1997, the book follows three Harvard-trained physicists named Sabine. Their work at Riverbank spanned nearly three quarters of the twentieth century.

Wallace Clement Sabine, the father of the science of architectural acoustics, designed the Riverbank laboratory on Colonel George Fabyan's estate in Geneva, Illinois. It was finished just months before his death in 1919. Paul E. Sabine then led Riverbank through its formative years and was involved in founding the Acoustical Society of America. His son, Hale Johnson Sabine, carried that work forward in the 1950s and 1960s.

As Kopec writes, "That one family could have accomplished so much in one particular science is overwhelming."

Thank you for following along chapter by chapter. Whether you read every installment or are just discovering the story, the full book is ready for you.

Riverbank Laboratory Manager Eric Wolfram joined the Catalyst Conversations podcast ahead of this year's Catalyst Connect to talk about his exciting presentation, The Evolution of Acoustical Testing & Product Innovation.

"Catalyst Connect is a great opportunity for me to connect with acoustical consultants and influencers in the architecture industry, to hear what their needs are, what their concerns are, and to see how I can help." - Eric Wolfram

Have you ever been watching a movie and seen a character (banker, politician, mob boss, etc...) slam a heavy leather door shut, making the room go totally silent, and thought, does that actually work?

Well, we put it to the test. The team at Riverbank took a 1.4 mm sheet of premium top-grain cow hide leather and evaluated its sound transmission, and the results may surprise you.

Check out our latest novelty test report to see what we discovered about the acoustic properties of leather.

A legacy isn't measured by years. It is measured by the people it inspires.

For more than a century, the Sabine family helped shape the science of architectural acoustics.

In the final chapters of The Sabines at Riverbank, readers meet Hale Johnson Sabine, the third generation of Sabine acousticians. Through decades of research, leadership, and mentorship, Hale advanced acoustical science while helping establish many of the testing methods and standards the industry still relies on today.

Perhaps his greatest contribution wasn't a single paper or project, but the knowledge he shared. As one Riverbank researcher recalls, Hale patiently guided the next generation of acousticians, reminding them that everyone starts somewhere, and that curiosity, integrity, and a commitment to learning are the foundations of good science.

As we conclude The Sabines at Riverbank, we're reminded that the best innovations don't end with one generation. They become the foundation for the next.

When great acoustics go unnoticed, that's often the sign of great design.

Behind every successful concert hall is an acoustical consultant balancing science, architecture, aesthetics, and human expectations. Yet even the best designs can become the subject of criticism when plans change during construction or opinions are formed before a hall has time to mature.

Chapters 8 and 9 of The Sabines at Riverbank explore the realities of acoustical consulting through Paul Sabine's experiences on landmark performance halls, including the fascinating story behind Buffalo's Kleinhans Music Hall. His correspondence reveals the collaboration, and sometimes conflict, between architects, owners, musicians, and consultants as they worked toward a common goal: creating spaces where music could truly come alive.

Its a reminder that exceptional acoustics aren't created by chance. They're the result of careful engineering, collaboration, and a willingness to stand behind the science.

Read Chapters 8 and 9 to discover the challenges behind some of America's most celebrated performance halls.

How do you turn scientific research into an industry standard?

In the 1930s, Paul Sabine faced a challenge that still resonates today: how to ensure that acoustical testing produced reliable, comparable results regardless of where it was performed.

Through groundbreaking research, the creation of standardized testing methods, and the formation of the Acoustical Materials Association (AMA), Sabine helped establish the foundation for modern acoustical laboratory testing. His work brought manufacturers, architects, and scientists together to create common benchmarks for evaluating sound absorption and sound insulation.

At the same time, Sabine authored Acoustics and Architecture, a landmark text that helped make the science of sound accessible to engineers, architects, and the public. His research, publications, and consulting work influenced major projects across the country and helped transform architectural acoustics into a recognized engineering discipline.

Discover how Riverbank's work during the 1930s helped shape the standards and practices that continue to influence acoustics today.

What does it take to turn a new scientific field into a true science?

Chapters 4 and 5 of the Sabines at Riverbank follow Paul Sabine as he arrives at Riverbank Laboratories and begins the painstaking work of transforming acoustic from theory into measurable, repeatable practice.

From timing thousands of sound-decay experiments by hand to developing standards that shaped modern architectural acoustics, Sabine's work helped establish the foundations still used in sound testing today. Along the way, Riverbank became a center for innovation, influencing everything from building design and hearing research to the emerging motion picture industry.

These chapters also introduce the broader Sabine family's impact on Geneva, including Mabel Sabine's leadership in progressive education and the next generation's growing connection to Riverbank's scientific legacy.

Explore the people, discoveries, and determination that helped define a decade of groundbreaking acoustical research.

What happens when science, architecture, cryptography, agriculture, and eccentric ambition all collide in one place?

Chapters 2 and 3 of The Sabines at Riverbank explore the fascinating world of Colonel George Fabyan and the extraordinary Riverbank estate, a "community of thinkers" where groundbreaking acoustical research existed alongside codebreaking, experimental laboratories, Japanese gardens, exotic animals, and some of the most unconventional scientific minds of the early 20th century.

These chapters reveal how Riverbank became far more than a laboratory. It became a hub for innovation that helped shape modern acoustics and American cryptography.

Continue reading Chapters 2 and 3 to explore the remarkable history behind Riverbank's legacy.

Summer is almost here, and soon beaches across the country will buzz with lively conversations blending into the sound of crashing waves.

In open environments like these, sand is often seen as just a surface underfoot, but how well does it actually absorb sound?

We tested a 5.5-inch layer of sand to evaluate its acoustic performance across a range of frequencies.

Check out our latest novelty test report to see what we discovered about the acoustic properties of sand.
