Abstract
Every space, outdoor or indoor, exhibits different acoustic properties. These properties depend on the space's shape, size, and surface material; therefore, architects' design influences their resulting acoustical signature. This course introduces room acoustics and its applications in architecture and design.
Objective
The course lays out the theoretical background on how sound propagates in space, interacts with surfaces, and is ultimately perceived. Furthermore, hands-on exercises provide the tools to measure and analyse the acoustics of existing spaces and how to design and predict the acoustics of modelled spaces. The course provides a comprehensive understanding of acoustics and its practical applications in architecture, enabling students to apply their knowledge of acoustics in real-world scenarios.
Content
The course examines room acoustics and its applications in architecture and design. It introduces physiological and psychoacoustics by exploring audible space impressions in daily life and our ability to perceive and localise sounds. It provides the theoretical background on how sound propagates in space and interacts with surfaces by looking closely into reflection, absorption, and diffusion. It demonstrates basic mathematical and physics concepts such as decibels and reverberation time through practical examples and hands-on exercises. The course examines how headphones and loudspeaker systems made electroacoustics and their application in room acoustics simulation and auralisation, a tool for acoustic design in architecture. It provides the software and hardware tools to measure and analyse the acoustics of existing spaces. It demonstrates acoustic simulation tools for designing and predicting the acoustics of digitally designed spaces. The course concludes with a short design project, allowing students to apply their acquired knowledge. Lectures by guest speakers round up the content and broaden the focus outside the box.
