Calgary police are testing out a new device to target vehicles that make a lot of noise.

The device, which registers decibel levels, has been used in Edmonton for three years.

Sgt. Dean Vegso says throughout the month of August, police will test the device out in various parts of the city.

"We want to focus on the areas where the most complaints are coming from," said Vegso.

"If there's a section of the city where there's a high number of noise complaints in regards to vehicles, that's where we're trying to target our enforcement."

Vegso says most traffic ebbs and flows with noise.

"We're focusing on that vehicle that's making that excessive noise, they're trying to make the noise, and we'll watch those decibel levels spike up to 100, 110," he said.

"We don't need the instrument to get a conviction on that charge, but it will assist us with it."

During the test period, police will hand out warnings, but after that drivers can face fines under the Traffic Safety Act.
