From: Noise and mental health: evidence, mechanisms, and consequences
A Association (hazard ratios and 95% confidence interval) between transportation noise source (Lden) and mortality from all intentional self-harm (ICD-10: X60–84, excl. ICD-10 ×61.8, X61.9, X81–82) after multivariable adjustment including PM2.5 exposure. B Exposure-response relationships for the association between transportation noise source (Lden) and mortality from intentional self-harm (ICD-10: X60–84, excl. ICD-10 ×61.8, X61.9, X81–82). Vertical dashed red lines show source-specific WHO guideline levels: road traffic = 53 dB, railway = 54 dB, aircraft = 45 dB. Adapted from [60] with permission.
