Loud vehicle activity on 17 Avenue S.W. dropped during the City's August noise enforcement push, according to monitoring data released by the City of Calgary.

The City compared readings from a noise monitor near Tomkins Park for August 2026 with the same period last year. During enforcement hours, loud vehicle events fell 25.2 per cent, from 357 to 267, and average sound levels dropped from 71.18 dBA to 68.80 dBA. Across the full analysis period, loud vehicle events fell 10.7 per cent, from 801 to 715.

The City calls 17 Avenue its highest-priority vehicle noise hot spot. The biggest drops came while officers were actively on the street, which the City says points to the effect of awareness and a visible enforcement presence. It also notes that weather, traffic volumes and special events can affect sound levels, so the numbers aren't a perfect before-and-after comparison.

“The results show that when drivers understand the rules and see a visible enforcement presence, we can make a meaningful difference in reducing excessive vehicle noise and improving the quality of life for residents and businesses,” said Inspector Brad Johnson, head of the Traffic Safety Team.

The City says the data also shows the value of its citywide network of noise monitors, which helps it spot hot spots and track whether initiatives are working.
