『INTRODUCTION TO PROFESSIONAL AUDIO JOURNALS’ EDITION
Acoustical Engineering is colloquially called the Bible or “The Holy Grail” of electroacoustics. Serving as a major text for both newcomer and student, entry level and seasoned professional, this book has been not only read but relied upon since its first publication in 1957. In audio magazines and journals, hardly an issue passes without referencing Acoustical Engineering.
What makes this book so special? When RCA struck its deal with Eldridge Johnson to buy the Victor Talking Machine Co., little did they know that Frank Massa came with Nipper. Massa has the distinction of influencing Harry Olson, and together they co-authored two editions of Applied Acoustics in 1934 and 1939 while they both worked at RCA Camden. Later, Olson wrote Elements of Acoustical Engineering in 1940 with a second edition in 1947. The 1957 edition is really a “third edition” of ‘Elements.’
Olson rose through RCA’s ranks to Director of Acoustical and Electromechanical Research of RCA Labs’ Princeton and later became the Labs staff vice-president. Olson’s 100-plus patent credits include the velocity (or ribbon) and cardioid microphones and a myriad of loudspeakers and loudspeaker materials. He also spent time lecturing and was mentor to many students.
While his name appears on these and many other works, the significance is in his association with RCA—a giant in the burgeoning world of electronic sound. The people he closely worked with, and those who worked for him, are the pillars of the electroacoustical world. During the pioneering and fiercely competitive years when motion pictures acquired the ability to talk, RCA and Bell Labs poured unprecedented amounts of money into research. This never-to-be-repeated golden-era is really what Acoustical Engineering is all about, and Harry F. Olson was right there in the middle of it all.
Countless professional careers and technological influences are directly traceable to Acoustical Engineering. Because those seeking this book have rarely found it in the past, to many the search for Acoustical Engineering is a quest—a quest we are fulfilling with this new edition. We look forward to this classic touching the lives of the current generation and those to follow. Here’s hoping your search for “The Holy Grail” was fruitful.

『LINER NOTES FROM THE 1957 EDITION’S DUST JACKET
The momentous strides taken in recent years by modern acoustic science has made this new and greatly enlarged edition imperative. From fundamentals to practical applications, it now presents complete working methods covering the entire field of acoustical engineering.
In all of the diverse areas covered, rapid advances have made much new material and many revisions necessary. Two large chapters have been added, dealing with complete sound reproducing systems and communications systems. The most recent developments are all described including those: in underwater acoustics, systems for detecting and locating crafts and obstacles, and for depth soundings; in ultrasonics, industrial techniques for cleaning machined parts, for drilling and detecting flaws; in architecture, methods of obtaining excellent acoustics under severe artistic considerations; in music, new musical instruments.
Throughout the book consistent and logical use of analogies between electrical, mechanical and acoustical systems is made, for a reduction of a vibrating system to the analogous electrical network has been found a valuable tool in its analysis. Detailed presentations of theory and practice are given for all important transducers, and the material on speech, music and hearing correlates objective and subjective acoustics. As an aid in development and design, a large number of useful formulas, tables and graphs are included together with acoustical elements, radiating systems, and mechanical vibrating systems.
Here for radio, television, sound motion picture and recording engineers, architects and musicians, is an invaluable reference that reflects the most up-to-date information available today. 』

『PREFACE
The first edition of this book, published in 1940, was the subject matter of thirty lectures prepared for presentation at Columbia University. It was an exposition of the fundamental principles used in modern acoustics and a description of existing acoustical instruments and systems.
Many and varied advances were made in acoustical engineering in the seven years following the issuance of the first edition. The second edition of the book, published in 1947, covered the advances in acoustics which were made in the period between the first and second editions. Since the publication of the second edition, the developments in acoustics have been on an even greater scale than in the period between the first and the second editions. Today, the science of acoustics includes the generation, transmission, reception, absorption, conversion, detection, reproduction and control of sound. An important division of acoustical engineering is sound reproduction as exemplified by the telephone, radio, phonograph, sound motion picture and television. These sound reproducing systems are universally employed in all variations of modern living. The impact of the reproduction of sound by these systems upon the dissemination of information, art and culture has been tremendous.
The ultimate useful destination of all informative sound, direct or reproduced, is the human ear. In this connection, great strides have been made in obtaining knowledge on the characteristics and action of the human hearing machine. Measurements play an essential part in the advancement of any scientific field. Instruments have been developed and standards have been established for the measurement of the fundamental quantities in acoustics. The application of acoustics in the field of music have led to a better understanding of the stuff of which music is made. This knowledge has been applied to the development of new musical instruments employing the latest electronic and acoustical principles.
Accelerated by the requirements in World War II, tremendous advances were made in underwater sound. The developments in underwater sound have resulted in systems for detection and accurate location of underwater craft and obstacles over great distances, depth sounders and other acoustic applications in undersea communication. The industrial applications of ultrasonics have unfolded a new field in acoustics. Some of the important ultrasonic developments include the cleaning of

machine parts, drilling and flaw detection. The science of architectural acoustics has advanced to the point where auditoriums, studios and rooms can be designed to obtain excellent acoustics under severe artistic conditions. With ever increasing industrial expansion comes an increase in noise. Work is now under way actively to control noise by the use of a variety of acoustic countermeasures.
The preceding brief description of the present status of acoustics shows that it plays a very important part in our modern civilization. Furthermore, the fundamentals and applications of the science of acoustics are so well formulated and substantiated that a large area of the field of acoustics has attained an engineering status. In preparing new material and in revising existing material in the third edition, the same principles were followed as in the first and second editions. Particular efforts have been directed towards the development of analogies between electrical, mechanical and acoustical systems because engineers have found that the reduction of a vibrating system to the analogous electrical network is a valuable tool in the analysis of vibrating systems. Each chapter has been brought up to date and amplified. Two new chapters on Complete Sound Reproducing Systems and Means for the Communication of Information have been added. As in the first and second editions most of the illustrations contain several parts so that a complete theme is depicted in a single illustration.
The author wishes to express his appreciation to Miss Patricia Durnan for her work in typing the manuscript and to his wife Lorene E. Olson for assistance in compiling and correcting the manuscript.

『HARRY F. OLSON 1901-1982
HARRY F. OLSON was born in Mt. Pleasant , Iowa , and attended the University of Iowa , where he received his B.E. in 1924, his M.S. in 1925, his Ph.D. in 1928, the professional degree of Electrical Engineer in 1932, and an honorary D.Sc. degree from Iowa Wesleyan College , Mt. Pleasant , in 1959.
In 1928, he joined the Radio Corporation of America as a member of the Research Department. Except from 1930—32 while at RCA Photophone, Dr. Olson was continuously associated with the RCA research organization from 1928 to 1967. In 1934, he was placed in charge of acoustical research for the RCA Manufacturing Company, and became the Director of the Princeton Labs upon its creation in 1943. Dr. Olson continued to head RCA’s research activities in this field during the ensuing years, retiring as staff vice-president Acoustical and Electromechanical Research Laboratory.
One of Dr. Olson’s early contributions during his career with RCA was his pioneering work on the velocity microphone which became a standard in broadcasting. Subsequently, he co-developed several other types, including the uni-directional which became a standard in television broadcasting and sound motion picture filming. He also made milestone contributions to loudspeaker development, including the famed duo-cone loudspeaker for high-fidelity sound reproduction, and to the development and improvement of phonograph pickup and recording equipment, underwater sound equipment, and sound motion picture and public address systems. In addition, he guided and contributed substantially to the development of such novel systems as the RCA magnetic tape recorder for television (1957), the legendary RCA Electronic Music Synthesizer (1959) “capable of producing any real or imaginable sound,” and the multi-lingual phonetic typewriter (1961), forerunner to today’s voice recognition systems.
A frequent contributor to professional journals, Dr. Olson wrote several books, Dynamical Analogies, Applied Acoustics, Elements of Acoustical Engineering, Musical Engineering (reprinted as Music, Physics, and Engineering), and Modern Sound Reproduction, and held more than 130 U.S. patents on devices and systems in the acoustical field.
Recognized for his innovations, Dr. Olson was elected to the National Academy of Science in 1959, and later became a fellow of the American Physical Society, the Institute of Electronic and Electrical Engineers (IEEE), the Audio Engineering Society (AES), the Society of Motion Picture and Television Engineers (SMPTE), and the Acoustical Society of America (ASA). He was the editor and editor emeritus of the AES journal, and a president of both the AES and ASA.
For his contributions in the field of electroacoustical engineering, Dr. Olson received many honors including the Modern Pioneer Award of the National Association of Manufacturers in 1940; the John H. Potts Medal (now the Gold Medal) of the Audio Engineering Society in 1952 and the Emil Berliner Award (now the Silver Medal) in 1965; the Samuel L. Warner Medal of the Society of Motion Picture and Television Engineers in 1955; the John Scott Medal of the City of Philadelphia in 1956; and the John Ericcson Medal of the American Society of Swedish Engineers in 1964. He received four awards from the IEEE: the Achievement Award of the Professional Group on Audio of the Institute of Radio Engineers (now IEEE) in 1956; the Mervin J. Kelly Award in 1967; the Consumer Electronics Award in 1969; and the Lamme Medal in 1970. Dr. Olson was awarded the first Silver Medal of the Acoustical Society of America in 1974 and the Society’s Gold Medal Award in 1981. 』
