Dr. Mendel Kleiner received his M.Sc.Eng. degree in Electronic Engineering from Chalmers in 1969 and obtained the Ph.D. in Building Acoustics in 1978. From 1980 to 1995, Mendel Kleiner held a position as lecturer at Chalmers, teaching and doing research on active room acoustics and sound field simulation. In 1989, Dr. Kleiner was awarded the honorary title of ‘Docent’. During the period 1995-2013 Dr. Kleiner was professor at the Division of Applied Acoustic at Chalmers, continuing research on presence, dynamic sound field simulation, interaction between visual and auditory stimuli in human perception, scattering of sound by architectural objects, product sound quality, auditory icons, and the acoustics of organs and organ pipes. Dr. Kleiner retired from his chair in 2013 and is now Professor Emeritus at Chalmers pursuing his research interests and teaching room acoustics.
Current research interests are auditory presence, virtual acoustics and human behavior, sensory interaction, room acoustics and auralization (particularly spaces for music and worship), acoustic measurement, audio and electroacoustics, sound reproduction systems (microphones, loudspeakers and arrays), sound quality (vehicles, machinery, technical and communication systems), as well as musical acoustics.
In the summer of 2003 Prof. Mendel Kleiner moved to Rensselaer Polytechnic Institute (RPI) to become the director of the Program in Architectural Acoustics at its School of Architecture. While at RPI Dr. Kleiner was a tenured professor at the School of Architecture. In July 2005 Dr. Kleiner moved back to Chalmers and became Director of research and teaching within the Chalmers Room Acoustics Group, CRAG, in the division of Applied Acoustics.
Dr. Kleiner became a fellow of the Acoustical Society of America in 2000, and is a member of its technical committee on architectural acoustics. Dr. Kleiner was chair of the Audio Engineering Society’s technical committee for acoustics and sound reinforcement as well as its standards committee for acoustics during 1993-2011. In 1997, he was a visiting professor at the Environmental Research Laboratory, Kobe University, Kobe, Japan. Dr. Kleiner has been invited as lecturer for many international courses on Auralization arranged by the Acoustical Society of America and the Institute of Noise Control Engineering.
Dr. Kleiner is the author or co-author of more than 130 technical papers and holds two patents. Dr. Kleiner also works as a consultant in ultrasonics, audio and electroacoustics, as well as room acoustics (Please phone +46 70 877 9669 for further information).
In 2010 Prof. Kleiner co-authored a book on the acoustics by churches, mosques and synagogues with David L. Klepper and Father Rendell R. Torres. The book Worship Space Acoustics, published by J. Ross Publishing, is a unique guide to the design, construction, and use of religious facilities such as churches, synagogues, and mosques, for optimum acoustics. The book is divided into two parts: Part I discusses methods and techniques of room optimization, including how the acoustics of large and small spaces are designed, implemented, and adjusted; how acoustical privacy is attained; noise and its control; sound reinforcement; and numerical and physical modeling techniques. Part II provides the architect, student, and lay person a review of the characteristics of the religious services pertinent to various beliefs and how these are provided for in the acoustic design of spaces in churches, mosques, and synagogues. The book is available from Amazon at

In 2011 the 3rd edition of Prof. Kleiner’s book Acoustics and Audio Technology was published by J. Ross Publishing. This is a new, considerably revised, and expanded version of the book Audio Technology and Acoustics previously published in two editions at Chalmers University.
Acoustics and Audio Technology, 3rd edition, is an introductory text for students of sound and vibration as well as electrical and electronic engineering, civil and mechanical engineering, computer science, signals and systems, and engineering physics. A basic knowledge of basic engineering mathematics and physics is assumed. Problems are included at the end of the chapters and a solutions manual is available to instructors. This classroom-tested book covers the physical background to and mathematical treatment of sound propagation, the properties of human hearing, the generation and radiation of sound as well as noise control, and the technologies used for pickup, recording, and reproduction of sound in various environments, and much more. The book is available from Amazon at
Electroacoustic devices such as microphones and loudspeakers are used everywhere sound needs to be picked up or broadcast, from cars and mobile phones to homes, places of worship, and sports arenas. They are a key part of the modern communication society, helping to transmit information to our ears. Mendel Kleiner’s book Electroacoustics explains the design of these sound transducers and also examines the compromises that are necessary when designing transducers for use in the real world.
Published in 2013, Electroacoustics is a modern textbook alternative to the classical books on electroacoustics and is based on the author’s extensive experience teaching the scientific and engineering principles of electroacoustics to advanced graduate and graduate students.
Electroacoustics uses electrical circuit analogies to help readers quickly grasp the fundamentals of acoustical and mechanical systems. The book covers both traditional electrodynamic audio and ultrasonic transducers and includes up-to-date material on arrays, planar transducers, loudspeaker enclosure design, and more. Since the book also includes background material on room acoustics, electrical circuits, and electrical filters it can be used by readers without a background in electrical engineering. Each chapter also features review questions and detailed, individual problems at the end of most chapters, making the book suitable for both teaching and self-study. Basic ideas are explained with the help of simple engineering math. The book is available from Amazon at
Much time is spent working out how to optimize the acoustics of large rooms, such as auditoria, but the acoustics of small rooms and environments can be just as vital. The expensive sound equipment of a recording studio, or the stereo in a car or living room are likewise rendered useless if the acoustic environment is not right for them.
Changes in wavelength to room size ratio and the time difference between the direct and reflected sound at the listening location mean that the acoustics of small spaces are quite different to those of large spaces. Tackling these specific aspects of physics, sound perception and applications for small spaces, this book brings together the important themes of small room acoustics.
Published in 2014, the book Small Room Acoustics covers this field of room acoustics. It is co-written by Mendel Kleiner and Prof. Em. Jiri Tichy at Penn State University. The book merges the physics, sound perception and applications for small spaces having volumes less than about 200 cubic meters. The major differences between the sound propagation and listening condition in large (widely covered in literature) and small rooms are due to the soundâs wavelength to room size ratio and the time differences between the direct and reflected sounds at the listening location. Distinct resonances at the low frequencies and small time differences between the direct and reflected sound result in sound coloration and distorted image localization. The book will provide the reader with a full physical description of sound fields, sound perception, possible remedies of the sound field non-uniformities, and examples of practical solutions in small rooms such as living rooms, control rooms, and music practice rooms.
