Acoustic Engineering 2

This activity asks students to use the CAFEQUE (Cost, Aesthetics, Function, Ergonomics, Quality, User, Environment) principles to analyse Bang & Olufsen earphones.

A link is given to a case study of the marketing of these earphones, which students then use as a standard or model to analyse their own headphones/earphones and to produce a critique of them, focusing on which areas they would develop and why. This leads to the production of a detailed design-development sheet using a range of presentation techniques, such as CAD, 3-D modelling, exploded views and sections.

The resource, from the Institution of Engineering and Technology (IET), is one of a number of activities which explore ergonomics and aesthetics in an authentic context, and supported by the Sound Design film. The full set of resources for this topic can be found in the Sound Design collection.
