60+ International Standards
SoundPLAN supports the most comprehensive collection of noise prediction standards worldwide, ensuring compliance with local regulations anywhere you operate
SPD - Spectral Propagation Difference
The SPD function is a groundbreaking feature exclusive to SoundPLAN that enables unprecedented flexibility in noise modeling. SPD calculates the difference between emission and immission spectra, allowing you to:
- Apply any propagation model to any source type with full spectral accuracy
- Combine different calculation methods within the same project seamlessly
- Handle complex multi-source scenarios with mixed standards (e.g., road + rail + industry)
- Maintain full frequency-dependent calculations even when mixing propagation methods
No other noise modeling software offers this level of flexibility and accuracy in combining different calculation standards within a single integrated model.
