Russian Engineers Give Every Car a Unique Acoustic Signature
New system identifies noisy vehicles by analyzing their sound profiles
Researchers in Russia have developed a system that can pinpoint noisy vehicles within traffic. The project, led by specialists at Perm National Research Polytechnic University, analyzes road noise using dedicated software that assigns each vehicle a unique “acoustic signature.”
Residents, Drivers, and Pedestrians Affected
The new software can identify specific vehicles that exceed noise limits, potentially forming the basis for next-generation traffic monitoring systems.
Noise pollution affects nearby residents, drivers, and pedestrians alike. Existing control systems measure only the overall noise level of traffic, making it difficult to identify individual offenders. The new approach records road noise and processes it using specialized software, assigning each vehicle a distinct acoustic profile.
According to the researchers, when the sound of a passing car is recorded and broken down into frequencies using mathematical transformations, it produces an amplitude-frequency profile. This profile is unique to each vehicle and remains identifiable even at different speeds. The system could help authorities detect violators and enforce regulations, encouraging drivers to maintain their vehicles properly.
Tracking Violators by Sound
The team plans to integrate the technology into intelligent transport systems in the Perm region. Narrow-direction digital microphones will be installed at specific locations to collect acoustic data.
In the future, the accumulated data could also help improve urban planning and contribute to the development of more effective noise regulations.
Earlier, we reported on how Moscow’s Gorky Park is measuring decibel levels and what artificial intelligence can detect.
