Learning Objectives:

  1. Describe how noise can negatively impact physiological and psychological health, learning, and productivity.
  2. Define key terms related to acoustic performance, including Noise Reduction Coefficient (NRC), Sound Transmission Class (STC), and Ceiling Attenuation Class (CAC).
  3. Explain how to use the Optimizing Absorption matrix to select the right absorption performance (NRC) for a project.
  4. Define Good, Better Best Sound Transmission Class (STC) blocking categories and describe how to use the Optimizing Blocking matrix to select the optimal STC for a project.
  5. Explain how lightweight plenum barriers can be used to control sounds when walls do not extend full height.
  6. Explain how to determine the required background sound level based on the wall blocking capacity.

Noise can have negative physiological and psychological impacts on building occupants, and can compromise learning and productivity. Past approaches to acoustic design did not adequately mitigate noise within buildings; however, new standards and strategies are improving acoustic performance, with positive benefits to occupant health and well-being. In this course, the student will learn how to implement a three-step process to achieve optimized acoustics, by selecting ceiling absorption, wall sound insulation, and background sound level. This course will introduce the reader to key terms related to acoustic performance, including Noise Reduction Coefficient (NRC), Sound Transmission Class (STC), and Ceiling Attenuation Class (CAC). The student will learn how to select the appropriate ceiling absorption and wall insulation for a particular application, and will also learn how lightweight plenum barriers can be used to achieve effective sound blocking when walls do not extend full height. Finally, this course will instruct the reader how to design the appropriate background noise level based on wall blocking capacity.
