Architectural acoustics deals with the design and construction of accoustically good buildings, music halls, sound recording rooms and movie theatres where the audience receive the best sound quality. In 1911, Wallace C. Sabine, professor of physics at Harvard university laid the foundations of acoustic engineering. Here, we see some definitions of sound:
