Introduction
What is architectural acoustics?
Architectural acoustics is the science and art of designing spaces that have optimal sound quality for their intended use. It involves understanding how sound behaves in different materials, structures, and environments, and applying this knowledge to create spaces that enhance speech intelligibility, music quality, privacy, comfort, and enjoyment. Architectural acoustics also deals with preventing unwanted noise from interfering with the desired sound, such as traffic noise, HVAC noise, or noise from adjacent rooms.
Why is architectural acoustics important?
Architectural acoustics is important because it affects how we perceive and experience spaces. Good acoustics can make a space more functional, pleasant, and attractive, while bad acoustics can make a space unusable, annoying, or even harmful. For example, good acoustics can improve learning outcomes in classrooms, enhance productivity in offices, increase sales in retail stores, and create a sense of awe in concert halls. On the other hand, bad acoustics can cause stress, fatigue, headaches, hearing loss, poor communication, and dissatisfaction in various settings.

Main Content
What are the main topics covered in Architectural Acoustics by M David Egan?
Architectural Acoustics by M David Egan covers the following six main topics in detail:
Basic principles of sound and hearing
This topic introduces the fundamental concepts of sound and hearing, such as sound waves, frequency, amplitude, decibel, sound pressure level, sound power level, sound intensity level, pitch, loudness, timbre, masking, reverberation, reflection, refraction, diffraction, absorption, transmission, and human ear anatomy and physiology.
Sound absorption and noise reduction
This topic explains how to reduce the amount of sound energy that is reflected or transmitted by surfaces and materials, and how to measure and evaluate the sound absorption properties of various materials, such as porous absorbers, panel absorbers, resonant absorbers, and composite absorbers. It also discusses how to design spaces that have appropriate reverberation times and background noise levels for different purposes.
Sound isolation and criteria for noise
This topic describes how to prevent sound from traveling from one space to another through walls, floors, ceilings, doors, windows, and other openings. It also presents the methods and standards for measuring and rating the sound isolation performance of various building elements and assemblies, such as sound transmission class (STC), impact insulation class (IIC), noise reduction coefficient (NRC), and noise criteria (NC).
Control of HVAC systems noise and vibrations
This topic addresses one of the most common sources of noise in buildings: heating, ventilation, and air conditioning (HVAC) systems. It covers the causes and effects of HVAC noise and vibrations, such as fan noise, duct noise, equipment noise, structure-borne noise, and flow-induced noise. It also provides guidelines and techniques for controlling HVAC noise and vibrations at the source, along the path, and at the receiver.
Auditorium acoustics design
This topic focuses on the design of spaces that are intended for speech or music performance or reproduction, such as auditoriums, theaters, concert halls, churches, lecture halls, classrooms, conference rooms, and recording studios. It covers the acoustical criteria and objectives for different types of auditoriums, such as clarity, intimacy, warmth, liveness, spaciousness, envelopment, balance, blend, and loudness. It also discusses the design factors and strategies that affect auditorium acoustics, such as room shape, size, volume, proportion, configuration, orientation, surface treatment, seating arrangement, stage design, and sound reinforcement system.
Electronic sound systems
This topic covers the basics of electronic sound systems that are used to amplify or reproduce sound in various spaces. It introduces the components and functions of electronic sound systems, such as microphones, mixers, amplifiers, speakers, equalizers, crossovers, and feedback control devices. It also explains how to design electronic sound systems that meet the acoustical requirements and expectations of different spaces and users.
What are the main features of Architectural Acoustics by M David Egan?
Architectural Acoustics by M David Egan has the following four main features that make it a unique and valuable resource for anyone interested in architectural acoustics:
Highly illustrated format
The book has more than 540 illustrations that are not merely supplements to the text as with nearly all traditional books. In this book, the illustrations are the core of the coverage of the topics. The illustrations are clear, concise, and informative. They help the reader to visualize and understand the concepts and principles of architectural acoustics more easily and effectively.
Concise and clear presentation
The book is written for architects, interior designers, engineers, and all others concerned with the design and construction of buildings who need to know the basics of architectural acoustics, but who do not have the time to digest wordy presentations. The book is concise and clear in its presentation of the topics. It avoids unnecessary jargon and technical details. It uses simple and straightforward language and examples. It summarizes the key points and highlights the practical implications of each topic.
Practical and relevant examples
The book provides many practical and relevant examples of architectural acoustics applications in various types of buildings and spaces. The examples illustrate how the concepts and principles of architectural acoustics can be applied to solve real-world problems and challenges. The examples also demonstrate how good acoustical design can enhance the functionality, aesthetics, and user satisfaction of different spaces.
