Lecture: Acoustic Basics II
  • Difference between geometric and statistical room acoustics
  •  Absorption: effect and measurement
  •  Resonators: principles and calculation
  •  Cross-sectional jumps: effect and impedance
  •  Room acoustics: impulse response, dimensions and their measurement/calculation/evaluation
  •  Methods for the auralization of sound
  •  Architectural acoustics: basics, sound reduction index

Walk - Acoustic Basics II

  1. Absorption
    The absorption of sound waves in a room is one of the most crucial aspects in designing acoustic conditions. Determining the absorption capacity of materials can be done in several ways. Here, the determination of the reflection factor for plane waves in Kundt's tube and the measurement of the absorption coefficient in the reverberation chamber are described. Learn more...
  2. Resonators
    This section establishes the relationship between wave propagation at interfaces and the effect of various resonators, which are fundamental both for room acoustics and musical acoustics. Learn more...
  3. Room acoustics
    Room acoustics deals with sound fields within rooms. Acoustic measurements are defined to describe the auditory impression of a room, corresponding to the perception of sound. The most important measure is the reverberation time of a room. Other measures describe the energetic distribution of early and late reflections as well as the reverberation. Acoustic modeling allows predicting the acoustics during the planning phase of buildings and the impact of structural changes. Learn more...
  4. Auralisation
    Auralisation refers to the audible rendering of real or virtual acoustic signals. The modeling of sound fields can be based on acoustic measurements of real rooms or simulated spaces. In any case, the result of the modeling should produce a plausible auditory impression. Modeling can, for example, be used to estimate the building or room acoustics during the planning phase of buildings and the impact of structural changes based on audio samples. Learn more...
  5. Soundproofing
    The transmission of sound waves from the environment into the room is very important for undisturbed work. The branch of acoustics that deals with these phenomena and the resulting measures for soundproofing is called building acoustics. Learn more...
  6. Architectural acoustics
    Architectural acoustics is of great importance for the sound engineer's daily work. Since all music recordings take place in rooms that are either connected to the outside by external walls or to other rooms by partition walls, floors, and ceilings, music recording is affected by sound that is not directly under the sound engineer's control. This section explains methods for describing the methods and parameters associated with this problem. Learn more...
