IHTAclassroom: 3D Architectural Model for VR Sound Perception Research

IHTAclassroom provides visual and acoustic 3D architectural models of a lecture classroom at the Institute of Hearing Technology and Acoustics (IHTA), RWTH Aachen University. The dataset includes geometry, materials, and light sources at multiple levels of detail (LOD) for visual cues, and high-LOD geometry for acoustic cues. It was created by Josep Llorca-Bofí and used in a 2021 publication in Frontiers in Built Environment.

Use Cases

• Developing VR environments for acoustic experiments based on the detailed 3D classroom model.
• Studying the impact of visual detail (LOD) on sound perception in virtual reality based on the separate visual and acoustic cue modules.
• Creating immersive educational or training simulations using the provided Unreal Engine scenario setup.

Strengths

• Provides separate data modules for visual and acoustic cues, allowing for controlled experiments.
• Includes multiple levels of detail (HighLOD, MediumLOD) for visual geometries, materials, and light sources.
• Offers a pre-configured scenario in Unreal Engine format for immediate use.

Limitations

• The current version includes only the modules used for the referenced 2021 paper; other LODs may be incomplete.
• Dataset scale (rows, file size) and specific file formats beyond FBX and JPEG are unknown.
• Last update date is unknown; freshness unverified.
