St. Patrick's Church, Patrington - Model

Information

Description: 
St Patrick's Church in Patrington dates back to the medieval era and expresses the decorated design of English Gothic Churches of the early 14th century. It has a cruciform plan, with an external length of about 46 meters, a breadth of 27 meters and a height of 57.5 meters up to the very top of the central tower. The impulse responses were generated using a ray-tracing model. 3 sets of measurements were recorded for 3 different source-reciever configurations (S1-R1, S2-R2 and S3-R3). The positions of these sources and receivers are described in the attached diagram.
