Room Acoustics

Scientific area of pertinence: ING-INF/11

The course builds upon basic acoustics courses for applications to listening spaces. It provides the fundamentals that are required for understanding how sound is perceived in rooms, and includes methods for computing sound fields in rooms with wave theoretical methods; statistical methods; geometrical acoustics methods; and computational implementations. Acoustical measurement techniques, sound absorption, and psychoacoustic criteria for evaluation of room acoustic quality are covered as well.

Learning outcome

Knowledge
  • an in-depth understanding of theoretical models of sound fields in enclosures
  • an in-depth understanding of how sound is perceived in listening spaces
  • an in-depth understanding of room acoustics measurement techniques
Skills
  • determining the correct acoustic parameters for various listening environments
  • measuring the acoustic properties of a room
  • analyzing and predicting sound fields according to various theoretical models (including the use of computer implementations for some of such methods)
  • analyzing a measured, or predicted, room impulse response in terms of its psychoacoustic impact
  • finding adequate solutions for correcting the acoustics of various types of listening spaces: (classrooms, restaurants, rehearsal and listening room, studios and auditoria)

Learning methods and activities

Lectures, exercises and laboratory exercises.
