Noise in Southampton: roads, railways and how to check your property
Southampton is ringed by the M27 and reached by the M3, with the A33 and A35 carrying traffic into the city, the South Western Main Line serving it, and a major port and nearby airport adding their own activity. It is a city where several very different noise sources can be in play depending on the neighbourhood.

How noise varies across Southampton
Northern and eastern suburbs feel the M27 and the approach roads, central areas are shaped by the A33 and the railway, and properties near the port or under airport flight paths experience sources a standard road assessment would not capture. AcoustaPlot identifies the nearest and dominant source for your address, flags aircraft-noise proximity separately, and gives an honest rating for the specific property rather than the city as a whole.
How AcoustaPLOT assesses noise for your property in Southampton
AcoustaPLOT geocodes your property, identifies the nearest and dominant source, and estimates the daytime (Lden) and night-time (Lnight) levels at your facade — reading Defra's mapped value where available, or calculating it with the CRTN (road) and CRN (railway) methods and terrain data elsewhere.
