Compact Audio Design

Havelock North High School

This course provides students with an opportunity to learn about amplification in audio devices and to develop skills in designing and manufacturing a prototype sound system. It requires students to: assemble a kitset amplifier circuit and contain it in a case which has prescribed specifications; and to design a prototype sound projection system that incorporates the amplifier and speaker(s) for use in a specific location.

Technological Practice

  • Brief Development
    • Justify the nature of an intended outcome in relation to the need or opportunity and justify specifications in terms
      of key stakeholder feedback and wider community considerations.
  • Planning for Practice
    • Critically analyse their own and others' past and current planning practices in order to make informed selection and effective
      use of planning tools.
    • Use these to support and justify ongoing planning that will see the development of an outcome through to
  • Outcome Development and Evaluation
    • Critically analyse their own and others' outcomes to inform the development of ideas for feasible outcomes.
    • Undertake ongoing experimentation and functional modelling, taking account of stakeholder feedback and trialling in the physical and social environments.
    • Use the information gained to select, justify, and develop a final outcome.
    • Evaluate this outcome's fitness for purpose against the brief and justify the evaluation using feedback from

Technological Knowledge

  • Technological Modelling
    • Understand that functional models are used to represent reality and test design concepts and that prototypes are
      used to test technological outcomes.
  • Technological Products
    • Understand that technological products are made from materials that have performance

Nature of Technology

  • Characteristics of technological outcomes
    • Understand that some technological outcomes can be perceived as both product and system.
    • Understand how these outcomes impact on other outcomes and practices and on people's views of themselves and possible futures.
