This definitive guide covers the design and application of absorbers and diffusers in acoustics. Surface diffusion is a relatively young subject area, and diffuser design, application and characterisation are often not well understood. Although there is greater knowledge of absorption, it is also informed by new research. As two of the main design tools for altering the acoustic conditions of rooms, the correct use of absorbers and diffusers is important to the creation of quality acoustics. This text details the evolution and the current state of the art in diffuser and absorber research and application. It covers a range of practical and theoretical aspects, with extensive examples of installations and case studies to cater to practitioners working in the measurement, modelling and design of rooms, semi-enclosed spaces as well as in noise control. It is also invaluable for students and researchers wanting a grounding in acoustic treatment, as well as understanding the latest developments. All chapters have been revised and brought up to date in this new edition, with new applications, absorbers and diffusers featured. Sustainability, portable vocal booths, and fast time domain models for diffusers are just a few of the new sections. Improved techniques for measurement and prediction are included, as well as bringing old methods up-to-date with the latest refinements from standards and research. Most of the prediction methods in the book are now linked to open source implementations and downloadable MATLAB scripts, enabling readers to exploit the knowledge in this book more readily in design and research.

Trevor Cox is on a hunt for the sonic wonders of the world. A renowned expert who engineers classrooms and concert halls, Cox has made a career of eradicating bizarre and unwanted sounds. But after an epiphany in the London sewers, Cox now revels in exotic noises creaking glaciers, whispering galleries, stalactite organs, musical roads, humming dunes, seals that sound like alien angels, and a Mayan pyramid that chirps like a bird. With forays into archaeology, neuroscience, biology, and design, Cox explains how sound is made and altered by the environment, how our body reacts to peculiar noises, and how these mysterious wonders illuminate sound s surprising dynamics in everyday settings from your bedroom to the opera house. The Sound Book encourages us to become better listeners in a world dominated by the visual and to open our ears to the glorious cacophony all around us."

As an acoustic engineer, Trevor Cox has spent his career eradicating unwanted noises - echoes in concert halls, clamour in classrooms. Until the day he heard something so astonishing that he had an epiphany: rather than quashing rare or bizarre sounds, we should be celebrating these sonic treasures. This is the story of his investigation into the mysteries of these Sonic Wonders of the World. In the Mojave Desert he finds sand dunes that sing. In France he discovers an echo that tells jokes. In California he drives down a musical road that plays the William Tell Overture. In Cathedrals across the world he learns how acoustics changed the history of the Church. Touching on physics, music, archaeology, neuroscience, biology, and design, Cox explains how sound is made and altered by the environment and how our body reacts to peculiar noises - from the exotic sonic wonders he encounters on his journey, or the equally unique and surprising sounds of our everyday environment. In a world dominated by the visual, Sonic Wonderland encourages us to become better listeners and to open our ears to the glorious cacophony around us.

Mit dem Buch der Klange fuhrt uns der britische Wissenschaftler Trevor Cox in verborgene Hoerwelten. Es weckt in uns das Verlangen, in einem Alltag, in dem das Visuelle so sehr dominiert, doch einmal genauer hinzuhoeren - und unsere Ohren fur das wunderbare Klangdurcheinander um uns herum zu oeffnen. Als Fachmann fur technische Akustik hat sich Trevor Cox lange damit beschaftigt, unerwunschte Gerausche verschwinden zu lassen, ob Echos in Konzertsalen oder Larm in Klassenzimmern. Eines Tages aber verschaffte ihm ein Ausflug in die Londoner Kanalisation ein erstaunliches Hoererlebnis - und die Erkenntnis: Statt seltsame Gerausche abzustellen, sollten wir die seltsamsten und bizarrsten akustischen Effekte zu schatzen lernen: als die Klangwunder unserer Erde. Das Buch der Klange beschreibt seine Suche nach diesen Klangwundern. In der Mojave-Wuste besucht Cox singende Dunen. In Frankreich entdeckt er ein Echo, das zu Scherzen aufgelegt ist. In Kalifornien fahrt er eine "singende" Strasse entlang, die die Ouverture zu Wilhelm Tell erklingen lasst (wenn auch ziemlich schief). Und eine Entdeckung ist so beeindruckend, dass sie einen Eintrag ins Guinness-Buch der Rekorde verdient hat.

'A lively, intelligent and persuasive history of speech...Expertly and patiently explained' The Times Why are human beings the only animals that can speak? And why does it matter? If you've ever felt the shock of listening to a recording of your own voice, you realise how important your voice is to your personal identity. We judge others - and whether we trust them - not just by their words but by the way they talk: their intonation, their pitch, their accent. Now You're Talking explores the full range of our voice - how we speak and how we sing; how our vocal anatomy works; what happens when things go wrong; and how technology enables us to imitate and manipulate the human voice. Trevor Cox talks to vocal coaches who help people to develop their new voice after a gender transition; to record producers whose use of technology has transformed the singing voice; and to computer scientists who replicate the human voice in their development of artificial intelligence. Beginning with the Neanderthals, Now You're Talking takes us all the way to the digital age - with the frightening prospect that we may soon hear 'Unexpected item in the bagging area' more frequently than a friendly 'Hello, how are you?' in the street.

Hove, west of its immediate neighbour Brighton, was a small fishing village on the Sussex coast until its development in the early nineteenth century as a fashionable seaside resort for wealthy Londoners following the patronage of the prince regent, later George IV. Elegant Regency estates and large Victorian mansions were built in Hove, most of which survive today, albeit as flats, and the town is also characterised by the wide boulevards and avenues laid down in that era. Sussex Cricket Club made Hove its home, as did Brighton & Hove Albion FC until it relocated in the 1990s. Hove has always retained its separate identity to Brighton, and today is proud to be a counterpoint to its neighbour. Hove: The Postcard Collection takes the reader on an evocative journey into Hove's past through a selection of old postcards that offer a fascinating window into the history of this historic town in east Sussex.
