The American Wallace Sabine was the first modern scientist to study the actual acoustic behaviour inside a room such as a lecture theatre or concert hall in the 1900s, at a time before electrical microphones and loudspeakers were available. Furthermore, the passage of sound waves was invisible. He developed a technique of model testing using a spark to generate a sound and using schlieren photography to capture the passage of the sound waves. The Swiss acoustician Franz Osswald developed more accurate version of this technology in the 1930s. Other model studies of acoustic behaviour used light rays and water waves produced in a ripple tank. Quantitative studies of room acoustics became more accurate and useful with the development of new modelling techniques in the 1960s using electric microphones, amplifiers, loudspeakers and tape recorders. Early models at this time were made at 1:8 scale; with the development of more precise tools, it became possible to study models at 1:50 scale. By the 1970s many major concert halls were designed with the aid of scale‐model tests.
