Long considered one of the key books on the well-informed audio engineer’s shelf,Sound System Engineeringprovides an accurate, complete, and concise tool for all those involved in designing, implementing, and testing sound reinforcement systems. This new fourth edition includes eight new chapters leading the reader through both cutting-edge topics—e.g., IBM’s proposed thought-controlled sound system—and solid basics, such as loudspeaker specifications, wave equations, and digital audio.Topics covered include:Psychoacoustics and how the brain processes soundDigital theoryMathematics for audio systemsUsing the decibelInterfacing electrical and acoustical systemsAudio and acoustic measurementsLarge room and small room acousticsDesigning for acoustic gainDesigning for speech intelligibilityWave equationsMicrophonesLoudspeakers, loudspeaker arrays, and loudspeaker directivityPower ratings for amplifiers and loudspeakersComputer-aided system designSignal delay, signal synchronization, and signal processingSound system equalizationPacked with numerous illustrations and useful appendices, this is a concentrated capsule of industry standards and knowledge that spans the complete range of sound systems, from the simplest all-analog paging systems to the largest multi-purpose digital systems.
