What is LDEN?
LDEN is an environmental noise metric used to represent average noise exposure over a 24-hour period, applying additional weighting to evening and night-time noise to reflect increased sensitivity to disturbance during these times.
LDEN is a widely used environmental noise metric that represents average noise exposure over a 24-hour period. It applies additional weighting to evening and night-time noise, reflecting the increased potential for disturbance during these periods.
In this video, we explain:
- What LDEN is and how it is calculated
How LDEN is used in environmental noise assessments
Why it is important for noise mapping and planning decisions
If you’re involved in environmental noise assessment, acoustic consultancy, or planning and development projects, understanding LDEN is essential. Want to explore more acoustics and noise terminology? Visit the AcSoft Ltd Knowledge Hub for practical guides, FAQs, and the full acoustics glossary.
