Noise Simulation & Noise Frame ============================== **Noise Simulation** models how sound propagates from one or more **source points**, taking into account **obstacles**, **vegetation**, and **environmental conditions**. The outputs are **noise exposure maps** that are useful for **urban planning**, **environmental impact assessments**, and **acoustic zoning**. ---- The module provides several simulation methods depending on the required level of detail and computational performance. - **Full wave-based simulation** — physically detailed modeling of sound propagation. - **Simplified geometric frame** — faster approximate results for general assessments. ---- Full Wave-Based Simulation -------------------------- Performs detailed noise modeling using **wave-based acoustic calculations**. This approach accounts for reflections, diffractions, and absorption by materials. .. autofunction:: objectnat.simulate_noise .. figure:: https://raw.githubusercontent.com/DDonnyy/ObjectNat/assets/noise_simulation_1point.png :alt: noise_simulation_1point :align: center :width: 80% Example of full wave-based simulation for a single noise source. ---- Simplified Noise Frame ---------------------- Generates a **simplified noise exposure map** using only **geometric visibility** and **sound decay with distance**, without running a full wave simulation. Ideal for **rapid assessments** or large-scale analyses where precision is less critical. .. autofunction:: objectnat.calculate_simplified_noise_frame .. figure:: https://raw.githubusercontent.com/DDonnyy/ObjectNat/assets/noise_frame.png :alt: noise_frame :align: center :width: 80% Simplified geometric noise exposure frame — fast and efficient. ---- Additional Resources -------------------- For comprehensive documentation and advanced configuration options, see the project Wiki: `Noise Simulation on GitHub `_ ---- Example notebook ---------------- :doc:`examples/noise`
