Noise in Lincoln Heights
Modeled estimates for general information only — not measurements, not a guarantee, and not for legal, medical or real-estate decisions.
Across 33,670 modeled building-façade points in the Lincoln Heights Neighborhood Council area, the median 24-hour level is 56.2 dB CNEL; one point in ten is below 47.0 dB and one in ten above 67.7 dB. At night (10 pm–7 am) the median is 48.1 dB.
The Lincoln Heights Neighborhood Council area is one of the City of Los Angeles’ certified Neighborhood Council areas. Its figures use the boundary from the City’s Neighborhood Councils (Certified) map layer.

What the model shows as the main source
At 100.0% of the building-façade points in the Lincoln Heights Neighborhood Council area, road traffic is the largest modeled contribution to the 24-hour level; aircraft is the largest at under 0.1%, and rail is not modeled here.
Trains: not modeled here. Only the San Fernando Valley main lines are modeled (Metrolink’s Ventura County and Antelope Valley lines, Amtrak and Union Pacific freight, with horns at public crossings); light rail, Metro Rail, other Metrolink lines and rail yards are not.
Under 0.1% of the points here lie inside the estimated 55 dB CNEL airport line, the edge of the airport-contour estimate; aircraft below that line are not in the figures.
Helicopters are not mapped. Sirens are an optional map layer (an estimate of LAFD fire and ambulance responses, City of LA only), off by default and not in these figures.
More on each source: freeway and road noise, train and rail noise and LAX and aircraft noise.
Buildings
The model has walls for 6,818 buildings in the Lincoln Heights Neighborhood Council area. For 42.7% of them the loudest wall is at or above 60 dB CNEL, and for 20.7% at or above 65 dB CNEL. For at least 23.9%, the less-exposed side is 10 dB or more below the loudest wall.
Which side of a building a bedroom or window faces changes the modeled level there: on the decibel scale, a difference of about 10 dB is heard as twice or half as loud. On the map, selecting a building shows its loudest and its least-exposed wall.
About these figures
The points are building façades of all types, 4 m up and 2 m out from the walls of every kind of building, not only homes. Long walls and large buildings have more points, so the figures describe buildings, not people or households.
The model is uncalibrated. At a single spot it is typically about 6 dB off, higher or lower, and compared with measurements it reads about 3.6 to 4.4 dB high on average at measured sites where freeway noise dominates, with a wide spread. An area figure says nothing certain about any one building; look up an address on the map for its own modeled levels.
Partly modeled areas are described by their modeled part only. The figures come from building façades only, so open land does not affect them. On the map, land with no freeway or major road within 3 km has no computed value and shows the lowest color; that is an assumption, not a measurement.
Figures are road, rail and aircraft at building façades; the map’s background “city hum” layer is not included in these figures.
Not in the figures: helicopters (not mapped), sirens (an optional map layer, off by default), construction, events, nightlife, neighbors and sound indoors.
Neighborhood Council areas cover only part of the City of Los Angeles and overlap in places; a point in an overlap counts for each council, so council figures cannot be added up.
