Introduction to Acoustics
In a nutshell
Sound is everywhere, from speech and music, to traffic and everyday noise. Acoustics is about exploring the physics of these sounds and the psychology of how people react when hearing them. Acoustical engineering has endless applications, from designing loudspeakers in smart phones to creating spaces where audio is at its best. Where there is sound, there is the potential to reduce or improve it through Acoustical Engineering.
For over 60 years Salford has pioneered acoustics teaching and research and is recognised by the UK Institute of Acoustics with a route to Chartered Engineer status. Our acoustical and audio engineering degree will guide you through this creative area of science and engineering, through a suite of modules designed to embed theoretical knowledge and creative application, to help you become a world-class acoustic and audio professional. With a focus on real-world problems solving, you'll explore the principles of acoustics, analogue electronics, speech, environmental noise measurement, digital signal processing, psychoacoustics, audio systems and speaker design.

Environmental Noise Measurement
You will carry out measurement of environmental sound using appropriate sound measuring instrumentation. You will develop the ability to describe and explain the main provisions of current environmental noise legislation, and to interpret the requirements in order to carry out reliable measurements and apply acoustic theory to decisions about when, how and where to measure environmental sound.
Measurement Analysis and Assessment
You will develop an understanding of the relevant scientific principles underlying acoustic measurement techniques, and effectively undertake standardised acoustic measurements, taking full account of uncertainty introduced throughout the process.You will perform appropriate analysis of measured data, and communicate findings effectively to a specialist audience.
