Guest editors’ introduction to the special issue on “performance spaces for music: Acoustical and psychological measurements and their interactions” honoring Dr. Leo Beranek.

Abstract

This special issue of Psychomusicology: Music, Mind, & Brain, entitled "Performance Spaces for Music: Acoustical and Psychological Measurements and Their Interactions," is dedicated to Dr. Leo Beranek not only in acclaim of his 100th birthday in 2014 but also in recognition of his lifelong contributions to the field of architectural acoustics. The significance his work as a researcher, consultant, and author is manifested in countless ways and seems impossible to overestimate. His books, Music, Acoustics, and Architecture (1962), Concert Halls and Opera Houses: How They Sound (1996), and Concert Halls and Opera Houses: Music, Acoustics, and Architecture (2004, represent one of the most important textbook series in concert hall acoustics, and has significance far greater than the sum of its parts. The impetus from reading these works ranges from fuelling an individual's interest and enthusiasm for concert hall acoustics to building bridges between experts from different fields collaborating on concert hall projects, allowing both scientists and practitioners to figuratively stand upon Leo Beranek's "giant's shoulders" so as to see a little further.There is no doubt that the initial publication of Beranek's book in 1962 on concert hall acoustics triggered ongoing research on how sound is perceived in auditoria. This ranges from the initial works of Hawkes and Douglas (1971) in London, United Kingdom; the works by the Göttingen group (e.g., Gottlob, 1973); and research in Berlin, Germany; (Wilkens, 1977) to more recent works by Barron (1988) in the United Kingdom and Lokki, Pätynen, Kuusinen, and Tervo (2012) in Finland. Their studies and many others have refined the fundamental ideas that Leo Beranek had put into discussion.Scientific research on panel reflector arrays, audience absorption of grazing sound (also known as the seat dip effect), and interaural cross correlation as a predictor of spatial perception of sound all carry the distinctive signature of Leo Beranek's work as a consultant on many outstanding projects. Just to name a few, these
