Does Transport Noise Impact Property Value? Here’s What the Research Says
Location Matters—But Noise Can Cost You
“Close to public transport” is often marketed as a major selling point for home buyers. But new research shows that living too close to busy roads, railways, or flight paths can significantly reduce property values.
How Close Is Too Close?
Convenience is great—but what about the noise? Studies suggest that increased transport noise can lead to a noticeable drop in property prices. Here’s what you need to know before buying near major transport hubs.
New Research on Noise and Property Prices
A recent study by PropTrack and Ambient Maps analysed noise pollution across Victoria from roads, railways, and air traffic. Then it compared those findings with property sale prices over five months. The results were eye-opening:
- Road Noise: Every 10 dBA increase in road noise = average property value drop of 6%.
- Rail Noise: Every 10 dBA increase = average drop of 4% (even after factoring in convenience).
- Aircraft Noise: Every 10 dBA increase = average drop of 6–9%. Homes outside flight paths can be 20 dBA quieter—meaning big value differences.
Example: A 5% decrease on a $1 million property = $50,000 lost in value.
What Does 10 dBA Sound Like?
The study included a helpful comparison:
- 45 dBA: Quiet cul-de-sac, no through traffic.
- 55 dBA: Suburban street with light traffic.
- 65 dBA: Main road with buses and trams.
- 75 dBA: Six-lane arterial road with heavy traffic.
The Silver Lining
Buying near transport hubs can still make sense—especially if it helps you enter the property market sooner. Plus, there are ways to reduce noise:
- Double glazing windows
- Sealing gaps and installing solid core doors
- Soundproof curtains and insulation
- Acoustic panels for walls
Key Takeaway
Don’t let the “location, location, location” pitch push you into overpaying. Factor in noise levels when assessing property value—and consider soundproofing solutions if you buy near transport corridors.
