Acoustics of Auditoriums

A scientific publication written in the early 20th century, specifically around the 1910s. This work focuses on the examination of acoustical properties of auditoriums, particularly emphasizing the challenges and solutions related to sound quality and clarity in performance spaces. It serves as both an investigation into specific issues within a given auditorium and a more general study of acoustic principles applicable to auditorium design. The book details the acoustic deficiencies found in the University of Illinois Auditorium, highlighting problems such as excessive reverberation and disruptive echoes. Watson discusses the methodologies applied to diagnose these issues, including the use of innovative sound tracing techniques. Through systematic experiments, the author identifies key reflections and echoes caused by the auditorium's architectural features, including its curved walls and large arches. The findings lead to recommendations for improvements through the application of sound-absorbing materials and structural modifications, which aimed to enhance the overall auditory experience for both speakers and listeners. Watson's study also contributes to broader architectural acoustics knowledge, providing practical insights for future construction and design of similar spaces.
