Engineering Contradiction Analysis
1Measurement precision
If complex geometric objects are used to represent acoustic spatial information, then the accuracy of acoustic space representation is improved, but the computational complexity increases
Solution Approach 1:
The patent segments complex geometric objects into simpler constituent elements (vertices, edges, faces) and represents them using hierarchical data structures. This segmentation allows the system to process complex shapes by breaking them down into manageable components, reducing computational complexity while preserving geometric accuracy for acoustic simulations.
Solution Approach 2:
The patent creates simplified computational representations (copies) of complex geometric objects that retain essential acoustic properties. These simplified models serve as proxies for detailed geometries, enabling accurate acoustic impulse response generation without requiring full geometric complexity, thus reducing computational load.
2Measurement precision
If detailed mesh representations are used for acoustic objects, then the precision of sound propagation calculation is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary processing of geometric data into optimized data structures and pre-calculates certain geometric properties before acoustic simulations. This preliminary action prepares the data in advance, allowing faster processing during actual acoustic impulse response generation while maintaining calculation precision.
Solution Approach 2:
The patent implements dynamic processing strategies that adapt the level of geometric detail used based on the specific acoustic simulation requirements. This allows the system to use detailed mesh representations only where necessary for accurate sound propagation calculation, while using simplified representations elsewhere, optimizing the balance between precision and processing time.
