I’ve never been much of an academic. I tend to learn You could feel it traveling up and along the walls. It by a process of experimenting, making, learning could be activated by whistling (I would run down it and repeating. It was a surprise to be asked by the trying to ‘catch’ the sounds I made), banging sticks or RIBA to write a book, and that several architects had bouncing balls.

This is primarily because I have spent most of my career developing tools and techniques to explain I was always fascinated by the sounds and noises acoustics using sound instead of words.

I learned to of these thoughts and experiences will be useful to play musical instruments, both classical and modern, others in the future. listening to myself and others play in concert halls and rock clubs, subconsciously thinking about the relationship between sound and space. At a crucial moment around the age of 16, I stumbled on a prospectus for the University of Southampton. Acoustics was listed frst in the index. I read it, visited, and took the course. I have been practising some form of acoustic consulting, sound or multimedia design ever since.

Acoustic Terminology a space? Good acoustic design is inherent to captures key words that will likely be encountered architecture. Every decision you make about shape, in a working career as a designer. The Case Studies form, geometry, volume and materials defnes the present projects by type, to quickly understand acoustics. So how do you design proactively for the what is important and why, with project examples right outcomes, the frst time? for guidance. The intention is to foster an approach to thinking about sound at the start of projects, the Architects generally receive little, if any, education positive potential of using sound creatively, and in acoustics. In formulating design goals for to help engage your clients in dialogue about it. projects, acoustics is a low priority – except Hopefully it helps to elevate the acoustics profession when it is fundamental to a building’s function and its integration with other design disciplines. (e.g. a concert hall). This is a missed opportunity. Great aural environments can be transcendental. This book does not replace the essential role of the Acoustics is the invisible art.

It We should strive to create spaces that delight all requires integrated thinking from the start. the senses. The right blend of what you see and Understanding acoustics – the propagation of how it feels is what creates exceptional, emotionally vibration through air and solids, the conversion of engaging spaces. I advocate thinking about sound in vibration into sound, the range of subjective views on the way you design from the outset. Ask the question: what constitutes pleasant sound or unwanted noise 'How do I want people to feel in this space?' and at diferent frequencies (low, medium, high or to use consider every sense when you do. the musical analogy bass, mid, treble) is extremely complex. It requires a fundamental grasp of the Raj Patel, New York, February 2020 physics, engineering, art and psychology of sound. Experiencing acoustics during the design process by listening is now accessible using auralisation tools. Used well, this encourages better design outcomes. There are plenty of technical books on architectural acoustics for those who want to delve deeper into the subject. This book is intended to help those unsure why acoustics is important in design at all, approaching acoustics for the frst time, or as a refresher when starting work on new projects. It aims to capture the essential information needed to design well. The opening essays provide background and INTRODUCTION [ 1 ]
