Calgary noise data show loud vehicle events down 25.2 per cent on 17 Avenue S.W.

The City of Calgary issued the results of Operation Silent Night at 3:20 p.m. on Tuesday, Oct. 13, 2026. The initiative targeted vehicle noise on 17 Avenue S.W., which the City identified as Calgary's highest-priority vehicle noise hot spot.¹

The City analyzed data from a noise monitor near Tomkins Park. It compared the August 2026 enforcement period with the same period in 2025.¹

During enforcement hours, loud vehicle events fell from 357 in 2025 to 267 in 2026, a reduction of 25.2 per cent. Across the full analysis period, loud vehicle events fell from 801 to 715, a reduction of 10.7 per cent.¹

Average sound levels during enforcement hours fell from 71.18 dBA to 68.80 dBA, a decrease of 2.38 decibels. The City said the strongest reductions came during active enforcement periods.¹

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.¹Brad Johnson, Inspector and head of the Traffic Safety Team, in a City of Calgary release

The City said weather, traffic volumes and special events can influence sound levels. It said the monitoring data indicates a clear improvement during the operation period.¹

The City said its citywide noise-monitoring network provides objective information about loud vehicle activity. It said the monitors help identify noise hot spots, understand trends and evaluate initiatives aimed at improving community livability.¹

The City said Operation Silent Night demonstrates how data, technology and targeted enforcement can work together to reduce excessive vehicle noise. The release did not state whether the operation will continue or when further monitoring results will be published.¹
