This book is a fine, general HISTORICAL overview of more current uses of sound in its many different (mostly ARTISTIC) forms (though, many other volumes from the MIT Press are even better). It is NOT a book on "noise" qua signal processing or information theory or anything of that sort of technical nature. It's more of a history book for art history students (and others) interested in the sonic arts, or art forms that utilize sound to a great degree.
If you want a more techie kind of thing then, of course, don't buy this book...go to the more mathematically-based volumes on the (correct) subject matter and dive in (P.S. for the other reviewer; don't rip on a book for being something that it wasn't even trying to be in the first place. And, for the record, sound is not simply "noise"...go check out the work of John Cage).
