Matching pipe organs to room acoustics

New research aims to help organ builders better predict how the massive instruments will sound once installed. No other musical instrument can be compared with the pipe organ in terms of size, tonal range, loudness, or complexity. The largest organs have thousands of pipes, the longest of which can extend 32 ft (9.75 m) or more in length. Unlike smaller instruments, which are typically produced according to standard designs, every pipe organ that is constructed must be specifically tailored to the acoustic properties of the space—typically a church or concert hall—in which it will be installed. In other words, an organ’s sound cannot be judged independently of its venue.
