Predicting Outdoor Sound provides a scholarly yet practical examination of the phenomena that affect outdoor sound close to the ground and its prediction. It is devoted to bringing together theories and data to give both researchers and practitioners the basis for deciding which model to use in a given situation. The book covers recent advances in theory, new and old empirical schemes, available data and comparisons between theory and data. Detailed case studies of predictions and their uses are presented. There are chapters on ground impedance models and data, methods of measuring ground impedance, ground effects in homogenous atmospheres, sound propagation in refracting and turbulent atmospheres, sound propagation from moving sources, the performance of outdoor noise barriers, the effects of tall vegetation and both numerical and empirical methods for predicting the various influences on outdoor sound. International in its applications, and written by authors who have been key in many of the recent advances, Predicting Outdoor Sound is a definitive reference for the acoustic engineer.

During the late summer of 1862, Confederate forces attempted a three-pronged strategic advance into the North. The results at Antietam and in Kentucky are well known; the third offensive, the northern Mississippi campaign, led to the devastating and little-studied defeats at Iuka and Corinth, defeats that would open the way for Grant's attack on Vicksburg. Cozzens details the tactical stories of Iuka and Corinth, analyzing troop movements down to the regimental level and providing compelling portraits of the Generals involved.

The battles of Iuka and Corinth admittedly weren't the most significant conflicts of the Civil War, and truth to tell even most historians would have to pause for a moment before recalling them. It is true that the Confederates were indeed turned back, but even a complete victory would only have delayed somewhat General Grant's determination to strangle Vicksburg. And even though the Union's General Rosecrans won, the encounters in northeastern Mississippi only accelerated the downward slope of his career. Why then write a book on these obscure episodes? Independent scholar Peter Cozzens bravely admits that one reason was that they have been neglected by researchers and historians. More to the point, however, they also bring attention to a murky phase of the war, and highlight the personalities of the leaders involved on both sides. This is useful, because those who begin to study America's Civil War soon run into an awkward situation. The great battles and troop movements in the eastern states—Bull Run, Antietam, Gettysburg—are all straightforward, easy to find on maps, and simple to relate to the conflict's "big picture." The same is true of the Mississippi Valley campaign that cut the Confederacy in two. But the large core of the central Confederacy that lay between the two major theaters of war is not so easy to digest. It was a great featureless region of few resources and little strategic value, hosting a mishmash of minor campaigns undertaken by quarrelsome, second-rate generals. All the more reason, then, for this well-done account. Cozzens writes a dynamic narrative filled with real people fighting a typical war: soldiers marching and gossiping while their officerspuzzled over bad maps and scanty intelligence reports, wondering just what the enemy was up to. This is an appealing read, but not always a brisk one. YA readers can easily omit some chapters devoted to the eternal bickering among generals, and to the minutiae of small units being sent back and forth over back roads. The rest of the book is a fascinating insight into the way the Civil War was really fought: i.e., in boredom, confusion, and sudden drama.

During the late summer of 1862, Confederate forces attempted a three-pronged strategic advance into the North. The outcome of this offensive--the only coordinated Confederate attempt to carry the conflict to the enemy--was disastrous. The results at Antietam and in Kentucky are well known; the third offensive, the northern Mississippi campaign, led to the devastating and little-studied defeats at Iuka and Corinth, defeats that would open the way for Grant's attack on Vicksburg. Peter Cozzens presents here the first book-length study of these two complex and vicious battles. Drawing on extensive primary research, he details the tactical stories of Iuka--where nearly one-third of those engaged fell--and Corinth--fought under brutally oppressive conditions--analyzing troop movements down to the regimental level. He also provides compelling portraits of Generals Grant, Rosecrans, Van Dorn, and Price, exposing the ways in which their clashing ambitions and antipathies affected the outcome of the campaign. Finally, he draws out the larger, strategic implications of the battles of Iuka and Corinth, exploring their impact on the fate of the northern Mississippi campaign, and by extension, the fate of the Confederacy.

Peter Cozzens here presents the first book-length study of the battles of Iuka and Corinth. Fought under brutal conditions and resulting in extremely heavy casualties relative to the numbers engaged - at Iuka, nearly one-third of those engaged fell - Iuka and Corinth proved to be two of the most vicious battles of the war. Drawing on extensive primary research, Cozzens details the tactical aspects of each battle, analyzing troop movements down to the regimental level. In addition to a vivid and detailed battle narrative, Cozzens provides compelling portraits of the campaign's key leaders: Generals Grant, Rosecrans, Van Dorn, and Price. He exposes the consequences of their clashing ambitions and antipathies. Finally, Cozzens analyzes the larger, strategic implications of the northern Mississippi campaign, exploring the repercussions of the Confederate defeats suffered at Iuka and Corinth. This is a practical yet academically rigorous reference for acoustic engineers, especially those working on major projects where noise control is a key issue such as the design and construction of Heathrow Terminal 5 There was a festive air in Memphis, Tennessee, the second week of April 1862, a gaiety that seemed to mock at Southern misfortune.
