Noise is discussed in terms of a source–path–receiver model. After an introduction to sound propagation and radiation efficiency,
the quantities measured for noise control are defined, and the instruments used for noise measurement and control are described.
The noise emission of sources is discussed with emphasis on the determination of the sound power level of a variety of sources.
The properties of two very significant sources of environmental noise, aircraft and motor vehicles, are presented. Tire noise
is identified as a major noise source for motor vehicles. Criteria for the noise emission of sources are given, and the basic
principles of noise control are presented. A section on active control of noise is included.
The path from the source to the receiver includes propagation in the atmosphere, noise barriers, the use of sound-absorptive
materials, and silencers. Guidance is given on the determination of sound pressure level in a room when the sound power output
of the source is known.
At the receiver, the effects of noise are presented, including both hearing damage and annoyance. A brief section is devoted
to sound quality.
Finally, noise regulations and policies are discussed. Many activities of the US government are discussed, and information
on both state and local noise policies and regulations are presented. The activities of the European Union are included, as
are the noise policies in many countries.
