Advanced calculation methods for outdoor sound propagation Seminar

The path from a noise source to a receiver involves complicated mechanisms such as diffractions and reflections from obstacles, ground and material properties, as well as meteorological conditions. In this seminar, we present the methodology applied by P.E. Mediterranean Acoustics Research & Development for outdoor sound propagation applying advanced calculation methods for prediction and simulation purposes in a software application, Olive Tree Lab-Terrain. The methodology makes use of the image source method combined with visibility tracing techniques to implement a novel method of multiple path-detection. This takes into account reflections from finite impedance surfaces and finite-sized objects, applying Fresnel zone corrections as well as diffractions of unlimited orders from edges. These advanced methods are out of the laboratory and are now available to engineers in the field, making theory available in practice.

Demonstration workshop

After lunch (between 13:00 and 16:00), there will be an opportunity to attend an interactive demonstration of the software and to discuss any issues in more detail. Eirini will be joined in the workshop by Panagiotis Charalampous, Senior Programmer and Partner. To attend this session please contact Natasha Webb (details at the foot of the page), as places are limited.
