From the reviews: "Altered Sensations should of course be read by those with an interest in the science of sound and its development ... . a valuable resource for anyone seeking to identify nineteenth-century acoustic apparatus and indeed could serve as inspiration for anyone presenting physical acoustics demonstrations today. ... The volume is well endowed with scholarly endnotes to each chapter and a comprehensive bibliography; it is liberally illustrated ... ." (Tacye Phillipson, ISIS, Vol. 102 (4), 2011) Pantalony's work offers historians of technology and science and STS scholars an invaluable study of Rudolph Koenig's nineteenth-century acoustical workshop. In so doing, he explores in exquisite detail the importance of musical-instrument making to the production of scientific instruments and the crucial influence of market forces on Koenig's work. Rather than merely limiting himself to written sources, Pantalony forges a historical narrative based on a reading of the instruments themselves, in a sense providing us with an archaeology of artifacts. He also deftly recounts how crucial Koenig's instruments were to the development of nineteenth-century acoustics. This book superbly fills a tremendous gap in the secondary literature. Myles W.
