Abstract
With the image-source method the room acoustics can be visualized by plotting
image sources around the listener, which yields an intuitive illustration of acoustics.
Lately, the image-source method has been extended to also include edge
diffraction. In this paper, a visualization method for diffraction phenomenon is
presented, which illustrates how diffraction behaves in different conditions. As an
example, first- and second-order diffraction in loudspeaker enclosure is visualized.
1 Introduction
Visualization of sound field is useful in design of acoustics and in educational purposes.
For visualization, the sound field has to be either measured or modeled.
While measurement of 3D sound fields is in many cases impracticable, modeling
of an acous
