An Introduction to Acoustical Engineering
Acoustical engineers play a vital role in almost every field of technology, from the built environment to transport, from audio systems to green energy production, from underwater communication to medical imaging and treatment.
Acoustical engineers need to understand the physical mechanisms of sound wave generation, propagation, but they also need to understand the way we hear and respond to sound, the way acousticians quantify and measure sounds. Beyond that acoustical engineers need to know how their role addresses the needs of society, how to communicate, both with engineers from other disciplines and the public, and what their professional and ethical responsibilities are.
This module will be the first step in your journey to becoming a professional acoustical engineer. It consists of four inter-related themes.
The ACOUSTICAL ENGINEERING theme explores the questions of what an acoustical engineer does, who employs them, and how they benefit society. It surveys the wide range of engineering undertakings to which acoustical engineers can contribute, and deals with the ethical and societal responsibilities of a professional engineer.
The SOUND PERCEPTION theme introduces the human auditory system and how we assess hearing. It explores the relationship between objective measures such as amplitude and frequency to subjective phenomena, such as loudness and pitch. It explores how we quantify and regulate noise.
The PHYSICAL ACOUSTICS theme deals with mathematical models for the physical processes involved in acoustic wave motion. It shows how wave motion arises from the fundamental laws of fluid motion and develops the relationship between pressure fluctuations (which we hear as sound) and the associated fluid motion, making use of analytical techniques learnt in your Mathematics module, and drawing on concepts from your Thermofluids module.
In the DATA PROCESSING theme, you will be taught to use the Python programming language to process, visualize and (since this is an acoustics course) auralize data. You will learn to create and play audible sounds, analyse recorded sounds and make animations of wave motions to deepen your understanding of acoustical processes.
