Description
This course is aimed at anyone who is curious about the fundamentals of sound and acoustic design. It is a foundational course in acoustics targeted at the beginner level. It provides an introduction to acoustic theory and applications of acoustic design in the built environment .It is assumed that students have a basic understanding of mathematical concepts, but it is not essential to progress through this course.Topics covered include: what is sound, how we hear sound, measuring sound, sound outdoors, sound in rooms, acoustic properties of materials, sound insulation and impact noise. Demonstrations of concepts are provided with visualisations, videos and auralisations (audio files).Twelve case study topics are presented based on real engineering projects. The case studies range from the design of a theatre, acoustics in offices and impact noise in a residential apartment .By the end of this course students will have enough background knowledge in acoustics to understand how sound and acoustics influences engineering and architectural designs in the built environment.Detailed course content:Section 1.
