What This Patent Covers

This patent establishes strong protection for a sound pressure signal output device, method, and program that synthesize engine sounds from physical models. Its broad claims and the examiner's inability to cite prior art indicate a highly novel and robust intellectual property, offering a low invalidation risk and strong market exclusivity.

Competitive White Space

While this patent covers the core engine sound synthesis, it does not explicitly extend to advanced acoustic material simulation or active noise cancellation systems. Licensees could develop complementary IP in areas like spatial audio rendering for virtual environments or integrating synthesized sounds with haptic feedback systems.

Economic Impact

estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming an automotive manufacturer incurs ~$2.0M (AI est.) annually for acoustic design and evaluation costs (recording, engineer salaries, test vehicle operation) during new engine development. Implementing this technology eliminates recording tasks and is estimated to reduce development time by ~50%. This could lead to approximately a ~50% reduction in R&D costs, projecting an annual economic benefit of ~$1.0M (AI est.). Further material cost reductions from fewer prototypes are also anticipated.

Speed to Market
6× faster than in-house development
This technology has a proven track record of implementation and licensing, with its core algorithms already established. This enables adopting companies to achieve market entry significantly faster compared to in-house development from scratch. As it does not rely on physical recording data, the time-consuming data collection and preprocessing phases are eliminated, allowing for immediate integration into existing simulation environments or product development workflows. With validated acoustic synthesis logic, licensees can expect rapid validation and deployment, substantially reducing time-to-market.
