An Amphitheatric Hall Modal Analysis using the Finite Element Method Compared to in situ Measurements.
The distribution of the low frequency room modes is important in room acoustics. The Finite Element Method (FEM) is a powerful numerical technique for analyzing the behavior of sound waves in enclosures, especially irregular ones. Also, it is the method which produces reliable results in the low frequency range where other methods like ray tracing and image source methods fail. A modal analysis is presented using the FEM in a non rectangular, medium sized amphitheatric hall and we compare the calculated results with those obtained by on site measurements.
