Edgar Villchur, former President and Director of Research at path-finding Acoustic Research, Inc., has been not only a pre-eminent engineer and scientist in the field of acoustics, but an excellent teacher and writer. In the field of high-fidelity loudspeakers, Villchur was credited with inventing the acoustic-suspension loudspeaker (the AR-1 in 1954), now the standard low-frequency methodology used worldwide. By 1959 Villchur introduced the first commercial hemispherical ("dome") high-frequency tweeter. This design, incorporated in the AR-3 loudspeaker, has been considered to be one of the most accurate transducers ever designed, and an example of this loudspeaker is on permanent display in the Smithsonion Institution's Museum of American History. Villchur also designed a widely-copied turntable and arm before retiring to his work in hearing aids. He founded the nonprofit Foundation For Hearing Aid Research in Woodstock, New York.
It is Villchur's almost unique ability to synthesize difficult scientific principles into easily-understood ideas and concepts that makes his books so enjoyable. His current book parallels his former books and articles in this respect, and this rare ability makes this a must-read book for those interested in understanding more about the basic principles of acoustics. This book should be in every audiologist's library.
