Abstract
We have developed a Virtual Reality model for an Underground Loader for mines. One important part of the model is the Audio Rendering Subsystem for real-time noise generation. It replicates the sounds which are audible in the loader cabin. Audio Rendering Subsystem is built around the Audible Model Platform, which consists of engine noise and ventilation noise parts. Engine noise is re-constructed from the engine orders and engine broadband noise. The ventilation noise is generated based on the calculated air flow patterns within the cabin.
The cabin noise is generated by the model has been compared to binaural recordings in the real operating conditions and have found to be representative.
Future development steps include taking account the separately-driven cooling fans and the effects of the torque converter to the audible noise.
