MELVILLE, N.Y., August 5, 2020 – The Acoustical Society of America (ASA) continues to host virtual events in August as part of the International Year of Sound.

On Aug. 6, David Carreon Bradley was scheduled to present at a virtual talk, but he is unable to do so. Instead, Andrew Morrison will discuss how the acoustical physics of the steelpan helps machine learning algorithms process large datasets.

All events are open to the public, and admission is free. ASA encourages media, scientists, audio enthusiasts, students, educators and families to tune in.

Making meaning from data — from the acoustics lab to machine learning: Thursday, Aug. 6

Morrison, a professor of physics and astronomy at Joliet Junior College, was intrigued by the characteristic sound of a Caribbean steelpan drum, which is easy to recognize by ear and yet still does not have a full scientific explanation for the how this musical instrument produces the distinctive tone.

His virtual talk, “Making meaning from data — from the acoustics lab to machine learning,” starts at 1 p.m. Eastern U.S. on Aug. 6.

He will discuss what is known about the physics of the steelpan, how scientists have engaged with the public to help classify the data, and how machine learning algorithms are being used to help process large datasets. He will also discuss how this study is useful for illustrating some parts of the scientific process.

A question-and-answer period will follow.

Morrison’s research interests include using optical methods and machine learning analysis techniques to study the vibrations of musical instruments. He is a past chair of the ASA Technical Committee on Musical Acoustics, is actively involved in the ASA Committee on Education in Acoustics and has a passion for working with undergraduates in his laboratory.

The Acoustical Society of America is the premier international scientific society in acoustics devoted to the science and technology of sound. Its 7,000 members worldwide represent a broad spectrum of the study of acoustics. ASA publications include The Journal of the Acoustical Society of America (the world’s leading journal on acoustics), Acoustics Today magazine, books, and standards on acoustics. The society also holds two major scientific meetings each year.
