Mount Washington is home to about 14,357 residents across 14 census tracts. 3.8% of them are exposed to 60 dB or more of average-day road, rail and aviation noise. Within that, 0.9% face the most severe band — 70 dB or louder, the level at which sustained exposure starts to threaten hearing. A further 22.8% sit in the 45–60 dB band — a noticeable background hum rather than a hearing risk. That ranks Mount Washington #106 of 110 Los Angeles neighborhoods, quieter than most Los Angeles neighborhoods. Among Los Angeles neighborhoods it sits just below Winnetka (#105) and just above Northridge (#107).

Mount Washington 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 Mount Washington 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 Mount Washington. 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 →
