Northridge is home to about 68,785 residents across 29 census tracts. 3.6% of them are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 1.4% face the most severe band — 70 dB or louder, the level at which sustained exposure starts to threaten hearing. A further 48.2% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. That ranks Northridge #107 of 110 Los Angeles neighborhoods, quieter than most Los Angeles neighborhoods. Among Los Angeles neighborhoods it sits just below Mount Washington (#106) and just above Reseda (#108).
Northridge 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.

How Northridge compares
How this is measured
This is a transparent aggregation of federal data, not an estimate: the US DOT 2020 National Transportation Noise Map (road + rail + aviation), paired with Census population by the University of Washington and area-weighted to the Los Angeles Times boundary for Northridge. It does not count sirens, construction, nightlife or neighbors, and it resolves busy corridors better than quiet local streets. For your exact spot, measure it with the free online decibel meter →
