Early 1900s: The Birth of Acoustic Design in Interiors

In the late 19th and early 20th centuries, there was a significant advancement in the field of architecture with regard to acoustics, largely due to the groundbreaking work of Wallace Clement Sabine. Sabine is widely regarded as a pioneer in the science of acoustics, particularly for his influential work on the Fogg Art Museum at Harvard University in the 1890s.

This work laid the groundwork for the development of modern acoustic engineering. During this era, the primary focus of acoustic design was on practical functionality, aiming to reduce echo and enhance sound clarity in large spaces, particularly in venues such as theatres and auditoriums. Sabine's contributions in this period have had a lasting impact on architectural acoustics and continue to influence the design of spaces for optimal sound quality to this day.
