Noise prediction and rating methods, alongside an understanding of their impacts on human health, are crucial components of Environmental Impact Assessment (EIA) for environmental health. These methods help assess and manage noise pollution to mitigate its effects on human well-being and the environment.

### Methods of Noise Prediction and Rating

1. Mathematical Modeling
Mathematical models predict noise levels by considering parameters such as source characteristics, distance from the source, terrain, atmospheric conditions, and reflective surfaces. Common models include:
- The CoRTN Model (Calculation of Road Traffic Noise): Used to estimate noise levels from road traffic based on vehicle flow, speed, and distance.
- CadnaA Software: A computer-aided noise analysis tool used for modeling industrial, urban, and environmental noise.
- ISO 9613-2 Method: Calculates environmental noise attenuation during propagation, taking factors like meteorological ______ ________ _______ ____ _______ _______ _______ ____.
