This map shows modeled outdoor noise across McIntire Terrace Historic District at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

Population Above the EPA Outdoor Threshold
The EPA's 55 dBA outdoor reference level is a common benchmark for residential noise exposure, especially for activity interference, annoyance, and long-term community noise concerns. About 1,427 McIntire Terrace Historic District residents, or 45.4%, live above that level. By land area, 52.0% of McIntire Terrace Historic District is above 55 dBA.

Noise by Part of McIntire Terrace Historic District
Average noise levels for McIntire Terrace Historic District residents, grouped by direction from the center of McIntire Terrace Historic District. Southern McIntire Terrace Historic District carries the highest population-weighted average; Western McIntire Terrace Historic District carries the lowest. Just 10% of residents in Western McIntire Terrace Historic District live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Southern McIntire Terrace Historic District.
Central McIntire Terrace Historic District
40% of people above 55 dBA
Eastern McIntire Terrace Historic District
46% of people above 55 dBA
Northern McIntire Terrace Historic District
35% of people above 55 dBA
Southern McIntire Terrace Historic District
91% of people above 55 dBA
Western McIntire Terrace Historic District
10% of people above 55 dBA
Southern McIntire Terrace Historic District sounds about 117% louder than Western McIntire Terrace Historic District to the human ear, a 11.2 dBA gap. Every 10 dBA roughly doubles perceived loudness. Within any of these directions, two homes a quarter mile apart can still differ by 10 or more dBA depending on how close they sit to a major highway.
Loudest Road Corridors
The model evaluates every road in McIntire Terrace Historic District using federal traffic counts, posted speeds, heavy-truck ratios, and pavement type. The source level shown is the modeled noise at the road centerline, where it is loudest. Noise drops with distance, faster in vegetated areas and slower over open pavement.
How far back from I-70 do you need to be?
I-70 produces an estimated 73 dBA at its loudest centerline points. Noise drops logarithmically with distance, with the exact rate depending on what's between you and the road. Tree cover, walls, terrain, and pavement type all matter. At roughly a quarter mile back, traffic fades into the noise level of a soft rainfall.
Calculated from the model's calibrated attenuation formula. About 16% of McIntire Terrace Historic District sits under tree canopy (about average for neighborhoods) and roughly 43% is impervious surface like pavement and rooftops. Both are folded into the per-place decay rate above. Heavier canopy pulls noise down faster with distance; impervious surfaces slow the drop.
Rail Noise
Active freight rail runs through parts of McIntire Terrace Historic District. For most blocks the rail-only contribution is small. Combined road-plus-rail noise rarely exceeds road noise on its own. The exceptions are the handful of blocks within roughly a quarter mile of the right-of-way during pass-through hours.
Use the Rail toggle on the map above to isolate rail's contribution from road and aviation.
How Noise Is Distributed Across McIntire Terrace Historic District
The bar chart below shows the share of McIntire Terrace Historic District residents in each noise band. About 54% of residents live below the EPA's 55 dBA threshold, and roughly 20% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.
How McIntire Terrace Historic District Compares
McIntire Terrace Historic District sits the highest among the peer group. Below: how McIntire Terrace Historic District's average outdoor noise and share of residents above the EPA threshold compare with Brighton Historic District, putnam-historic-district-zanesville-oh, Wheeling Avenue Historic District, and Granville Historic District.
Average noise level (dBA)
McIntire Terrace Historic District's 55.9 dBA pop-weighted average is the highest among the peer group. Ohio as a whole averages 51.1 dBA and the U.S. averages 52.0 dBA. Both are lower than McIntire Terrace Historic District because most of either area is rural land away from major roads.
Share of residents above 55 dBA
About 45.4% of McIntire Terrace Historic District residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's more than any of its peer group. Measured by land area instead, 52.0% of McIntire Terrace Historic District's footprint sits above 55 dBA, against a Ohio average of 26.4% and a national average of 28.1%.
What This Means if You're Moving to McIntire Terrace Historic District
- Distance from highways matters more than the neighborhood name. Two homes in the same zip code can differ by 20 dBA if one sits 100 meters from I-70 and the other 500 meters away. The model captures this at 100-meter resolution, so noise exposure changes block by block.
- Tree canopy can help reduce modeled noise exposure. Roughly 16% of McIntire Terrace Historic District is under tree cover (about average for neighborhoods), and the dominant land cover is low-intensity developed land. Both are measured from federal USDA Forest Service and USGS satellite imagery at 30-meter resolution. Streets with 60% or higher canopy show 3 to 5 dBA lower noise than comparable streets with bare ground or pavement, which is why the per-place decay rate above already accounts for it.
Sources & Methodology
The BestNeighborhood noise model is calibrated against nearly one million federal ground-truth measurements across four states. Road noise is computed from segment-level federal traffic data and propagated outward using physics-based acoustic decay, with attenuation rates that depend on the surrounding land cover.
Federal datasets used:
FHWA Highway Performance Monitoring System: road geometry, traffic counts, lane configuration
U.S. DoT Bureau of Transportation Statistics National Transportation Noise Map: aviation and rail noise, road calibration ground truth
USGS / MRLC National Land Cover Database: land cover and impervious surface coverage
USDA Forest Service Tree Canopy Cover: vegetation density for sound propagation
U.S. Census Bureau TIGER/Line: block-level geography and population
U.S. EPA Levels Document: 55 dBA outdoor reference level
All inputs are published federal datasets. Block-level noise is computed by combining road, rail, and aviation sound sources in the energy domain, the same physics used in professional environmental noise assessments. Read the full methodology.
