Noise Levels in Como, MS | Find Quiet Neighborhoods With Our Sound Map

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 328 Como residents, or 9.2%, live above that level. By land area, 13.8% of Como is above 55 dBA.

Noise by Part of Como

Average noise levels for Como residents, grouped by direction from the center of Como. Northern Como carries the highest population-weighted average; Southern Como carries the lowest. Just 1% of residents in Southern Como live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Northern Como.

Northern Como sounds about 97% louder than Southern Como to the human ear, a 9.8 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 Como 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.

Rail Noise

Active freight rail runs through parts of Como. 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 Como

The bar chart below shows the share of Como residents in each noise band. About 90% of residents live below the EPA's 55 dBA threshold, and roughly 2% live in blocks above 60 dBA. Long-term exposure in that range is linked to elevated stress hormones and cardiovascular risk.

How Como Compares

Como sits at the quieter end of the spectrum. Below: how Como's average outdoor noise and share of residents above the EPA threshold compare with Sardis, Courtland, Tunica, and Coldwater.

Average noise level (dBA)

Como's 44.7 dBA pop-weighted average is at the quieter end of the spectrum. Mississippi as a whole averages 47.9 dBA and the U.S. averages 52.0 dBA. Both are lower than Como because most of either area is rural land away from major roads.

Share of residents above 55 dBA

About 9.2% of Como residents live in blocks where outdoor levels exceed the EPA's 55 dBA threshold. That's in the middle of its peer group. Measured by land area instead, 13.8% of Como's footprint sits above 55 dBA, against a Mississippi average of 17.8% and a national average of 28.1%.

What This Means if You're Moving to Como

• 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 Interstate 55 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 50% of Como is under tree cover (heavier than most cities), and the dominant land cover is pasture / hay. 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.
