They smelled the foul odors. They heard the power saw buzzing in the dead of night but neighbors never imagined the horrors happening right next door. The hot sultry night of July 22, 1991 was one the tenants of the Oxford Apartments would never forget. A panic stcricken young man--a pair of handcuffs still dangling from his wrists--ran out of Apartment 213 and told police an incredible tale of terror. Shaking with fear, he led officers back to his captor's lair, where they made the gruesome discovery. Inside were the body parts of at least fifteen men--including torsos stuffed into a barrel, severed heads in a refrigerator, and skulls boiled clean and stashed in a filing cabinet. Tacked to the freezer were Poloroid photographs of mutilated corpses. When investigators arrested 31-year-old Jeffrey Dahmer, they realized they had stumbled onto a "real-life Hannibal Lecter"--a sadistic murderer who told them he had saved a human heart "to eat later". What could turn a handsome, former tennis player, the son of middle-class parents, into a perverse serial killer whose unthinkable acts shocked the nation? The Jeffrey Dahmer Story takes you into Jeffrey Dahmer's twisted world of bizarre sexual encounters, mutilation and cannibalism--in one of history's most appalling true crime cases. With 8 pages of chilling photographs.

Long considered one of the key books on the well-informed audio engineers 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 topicse.g., IBMs proposed thought-controlled sound systemand 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.
