Methodology Notes

Where studies measure environmental noise broadly (road + rail + air combined), we disclose that framing explicitly in the on-site citation. Aircraft-specific findings are prioritized where available.

Where the WHO's 45 dB(A) guideline uses Lnight and NavCanada's published contours use Lden or Lmax, we disclose that methodological mismatch in the acoustic physics explainer on the What You Should Know page.
