M2 road noise: how it affects nearby properties
The M2 runs through Kent from the outskirts of London towards Canterbury and the coast, crossing the Medway and carrying a heavy mix of commuter and Channel-bound freight traffic. Because lorry noise is lower-pitched and travels further than car noise, the freight character of the M2 often makes night-time levels the deciding factor for the many homes near its Medway Towns sections.
Traffic on the M2
Around 70,000–90,000 vehicles a day, with a substantial cross-Channel freight share heading for the M20 and the ports. Traffic volume, HGV proportion and speed all influence how much noise reaches nearby homes. As a motorway, the M2 carries sustained high-speed traffic day and night, so night-time levels are often the key concern.
Areas near the M2
Passing through: Kent.
Housing across the Medway conurbation — Rochester, Chatham and Gillingham — sits close to the route, and the Medway viaduct raises the noise line above local screening for some properties. AcoustaPlot reads any Defra contour that applies to your address and otherwise calculates a terrain-aware level, distinguishing the exposed viaduct-side homes from those sheltered by cutting or distance.
How AcoustaPLOT assesses M2 noise for your property
AcoustaPLOT geocodes your property, identifies the nearest carriageway of the M2, and estimates the daytime (Lden) and night-time (Lnight) levels at your facade — reading Defra's mapped value where available, or calculating it from DfT traffic data with real elevation data elsewhere.

M2 noise: common questions
How much noise does the M2 make?
It depends on your distance from the carriageway, the traffic flow and the terrain in between. Around 70,000–90,000 vehicles a day, with a substantial cross-Channel freight share heading for the M20 and the ports AcoustaPLOT estimates the daytime and night-time level at your specific facade rather than quoting a single figure for the whole road.
Can a fence or barrier reduce M2 noise?
Often, yes. A well-placed barrier breaks the line of sight to the traffic and forces the sound to bend over the top, which costs it energy (insertion loss, per ISO 9613-2). Height, length and position all matter — the first two metres usually do most of the work.
Is a property near the M2 a bad buy?
Not necessarily — exposure varies enormously over a short distance, and terrain or existing screening can make a big difference. The only way to know is to check the exact address rather than the road as a whole.
