Long considered one of the key books on the well-informed audio engineer’s shelf, Sound System Engineering provides 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 sound Digital theory Mathematics for audio systems Using the decibel Interfacing electrical and acoustical systems Audio and acoustic measurements Large room and small room acoustics Designing for acoustic gain Designing for speech intelligibility Wave equations Microphones Loudspeakers, loudspeaker arrays, and loudspeaker directivity Power ratings for amplifiers and loudspeakers Computer-aided system design Signal delay, signal synchronization, and signal processing Sound 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.

A world-renowned criminal profiler takes a fascinating look at one of the most tragic mysteries in history. For more than two thousand years, the great pharaoh Cleopatra VII has been portrayed as a failed monarch. Various ancient sources state that she desperately ended her life with the bite of an asp, as her nemesis - the Roman general Octavian, later known as Augustus, the first Roman emperor - stormed Alexandria. Now, a completely unique interpretation of history is brought to light by world-renowned criminal profiler Pat Brown in her new myth-busting book, The Murder of Cleopatra. As host and profiler of The Mysterious Death of Cleopatra (Discovery 2005), Brown challenged the long-enduring myth that Cleopatra died via snakebite and that she committed suicide to avoid further humiliation. Using the techniques and methodology of investigative criminal profiling and crime reconstruction, The Murder of Cleopatra takes up where the Discovery Channel documentary left off. Brown's findings, borne of scientific method, rigorous inquiry, and deductive reasoning, will be revealed against a historical backdrop of mystery, drama, politics, danger, and romantic intrigue. The result: a thought-provoking analysis of the amazing woman Cleopatra truly was, a fascinating account of the queen's final desperate attempt to escape Egypt with her ships and treasure, and the brutal homicide that ended her life as the last Egyptian pharaoh.
