Grand Boulevard noise map: how loud is it?

Grand Boulevard is home to about 23,667 residents across 25 census tracts. 3.2% of them are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 0.6% face the most severe band — 70 dB or louder, the level at which sustained exposure starts to threaten hearing. A further 96.8% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. That ranks Grand Boulevard #75 of 77 Chicago neighborhoods, quieter than most Chicago neighborhoods. Among Chicago neighborhoods it sits just below Chicago Lawn (#74) and just above Dunning (#76).

Grand Boulevard mostly sits away from the loud corridors. Where the noise does climb it traces a single freeway, rail line or flight path near the edge of the neighborhood rather than the residential core, so the great majority of blocks stay calm. The map pinpoints exactly where the exposure is.
