dc.description.abstractDiffusion is used in room acoustics to distribute sound energy and reduce concentrated refected energy and is measured using a goniometer. This experiment explores an improved portable goniometer design with microphones rotated at 1.25 degrees apart in a full circle. The microphones are embedded in a thin, light arch with a radius at 2.5 and 5 meters to collect from 288 points compared to the current standard AES-4id-2001 which collects from 72 points in a semi-circle. The large radius is crucial to satisfy far-eld conditions and higher resolution to validate the physical theory of diffraction, edge diffractions, and improve data of diffusers, both manufactured and simulated.
