Architectural Acoustics is the study of how sound behaves within a space. At GTCMT, research is two-fold, focusing on the acoustics of historical theaters and modern techniques for evaluating human perception of room acoustics. Through the compilation of historical documentation, computer modeling, and simulation, the lab re-creates the acoustic environment within fallen theaters. This gives insight into how each theater sounded and allows the acoustical performance to be quantified and compared to modern standards. Research in historical acoustics has led to investigation of the relationship between the precision of a computer model and the perception of a virtual sound field within a space. Through extensive modeling, auralization, and listening tests, the lab is determining how a change in computer model complexity affects a change in sound perception.
The hybrid violin attempts to join acoustic and mechanical elements in a standard violin to unlock nontraditional new acoustic sounds.
The research in vocal acoustics focuses on the human voice as an instrument. The lab studies the vocal tract and how each of the formants shapes and affects the voice. A specific focus of the research in vocal acoustics is vocal health and studying the effects of vocal disorders on the acoustic output of the human voice. The lab explores how growths on the vocal folds alter their oscillatory motion and change the pressure waves they create, which ultimately affect their sound. The acoustics lab also looks at vocal disorders from the audio signal end and is working on a way to diagnose different vocal disorders using a signal processing and machine learning approach.
