The life and work of Renaissance man Leo Beranek: scientist, professor, engineer, busisess leader, inventor, entrepreneur, musician, television executive, philanthropist, and author. Leo Beranek, an Iowa farm boy who became a Renaissance man—scientist, inventor, entrepreneur, musician, television executive, philanthropist, and author—has lived life in constant motion. His seventy-year career, through the most tumultuous and transformative years of the last century, has always been propelled by the sheer exhilaration of trying something new. In Riding The Waves, Leo Beranek tells his story. Beranek's life changed direction on a summer day in 1935 when he stopped to help a motorist with a flat tire. The driver just happened to be a former Harvard professor of engineering, who guided the young Beranek toward a full scholarship at Harvard's graduate school of engineering. Beranek went on to be one of the world's leading experts on acoustics. He became Director of Harvard's Electro-Acoustic Laboratory, where he invented the Hush-A-Phone—a telephone accessory that began the chain of regulatory challenges and lawsuits that led ultimately to the breakup of the Bell Telephone monopoly in the 1980s. Beranek moved to MIT to be a professor and Technical Director of its Acoustics Laboratory, then left academia to found the acoustical consulting firm Bolt, Beranek and Newman. Known for his work in noise control and concert acoustics, Beranek devised the world's largest muffler to quiet jet noise and served as acoustical consultant for concert halls around the world (including the Tanglewood Music Shed, the storied summer home of the Boston Symphony Orchestra). As president of BBN, he assembled the software group that invented both the ARPANET, the forerunner of the Internet, and e-mail. In the 1970s, Beranek risked his life savings to secure the license to operate a television station; he turned Channel 5 in Boston into one of the country's best, then sold it to Metromedia in 1982 for the highest price ever paid up to that time for a broadcast station. “One central lesson I've learned is the value of risk-taking and of moving on when risks turn into busts or odds look better elsewhere,” Beranek writes. Riding The Waves is a testament to the boldness, diligence, and intelligence behind Beranek's lifetime of extraordinary achievement. Leo Beranek is a pioneer in acoustical research, known for his work in noise control and the acoustics of concert halls, and the author of twelve books on these topics. The many awards he has received include the Presidential National Medal of Science, presented in 2003.

This illustrated guide to 100 of the world's most important concert halls and opera houses examines their architecture and engineering and discusses their acoustical quality as judged by conductors and music critics. The descriptions and photographs will serve as a valuable guide for today's peripatetic performers and music lovers. With technical discussions relegated to appendices, the book can be read with pleasure by anyone interested in musical performance. The photographs (specially commissioned for this book) and architectural drawings (all to the same scale) together with modern acoustical data on each of the halls provide a rich and unmatched resource on the design of halls for presenting musical performances. Together with the technical appendices, the data and drawings will serve as an invaluable reference for architects and engineers involved in the design of spaces for the performance of music.

Acoustics: Sound Fields, Transducers and Vibration, Second Edition guides readers through the basics of sound fields, the laws governing sound generation, radiation, and propagation, and general terminology. Specific sections cover microphones (electromagnetic, electrostatic, and ribbon), earphones, and horns, loudspeaker enclosures, baffles and transmission lines, miniature applications (e.g. MEMS microphones and micro speakers in tablets and smart phones), sound in enclosures of all sizes, such as school rooms, offices, auditoriums and living rooms, and fluid-structure interaction. Numerical examples and summary charts are given throughout the text to make the material easily applicable to practical design. New to this edition: - A chapter on electrostatic loudspeakers - A chapter on vibrating surfaces (membranes, plates, and shells) Readers will find this to be a valuable resource for experimenters, acoustical consultants, and to those who anticipate being engineering designers of audio equipment. It will serve as both a text for students in engineering departments and as a valuable reference for practicing engineers. - Provides detailed acoustic fundamentals, enabling better understanding of complex design parameters, measurement methods and data - Extensive appendices cover frequency-response shapes for loudspeakers, mathematical formulas and conversion factors
The book provides a pedagogical approach that emphasizes the physical processes of active materials and the design and control of engineering systems. It will also be a reference text for practicing engineers who might understand the basic principles of active materials but have an interest in learning more about specific applications. The text includes a number of worked examples, design problems, and homework problems (with a solutions manual) that will be useful for both instructors and practicing engineers.
Long-awaited update and expansion of a widely recognised classic in the field by pioneering acoustics expert, Leo L. Beranek Builds upon Beranek's 1954 Acoustics classic by incorporating recent developments, practical formulas and methods for effective simulation Uniquely, provides the detailed acoustic fundamentals which enable better understanding of complex design parameters, measurement methods and data Brings together topics currently scattered across a variety of books and sources into one valuable reference Includes relevant case studies, real-world examples and solutions to bring the theory to life Acoustics: Sound Fields and Transducers is a modern expansion and re-working of Acoustics, the 1954 classic reference written by Leo L.
