The local police service has had handheld noise meters in use off and on for the past few years. The use of them is spotty because in the beginning, charges were lost in court due to "creating reasonable doubt" in the judge's minds that reflecting sound waves off pavement, ambient noise from passing traffic and so on may have affected the readouts. The use of these 'wastes of money' has virtually stopped.
Enter the next level of enforcement. Pole mounted noise meters complete with cameras so tickets can be mailed out. Several of these over priced items were installed on main thoroughfares as well as in busy roadways through residential areas. They were installed last fall and turned on. A digital board showed the dB level of noise. Then the problems started. Individuals in the middle of the night would pause at them and scream toward the microphone to see how loud they could be measured. Residents complained and they were summarily turned off.
The handheld units were purchased for motorcycle enforcement only and that's not right. They aren't the only noise makers being driven on the roads. The pole mounted ones I assume are to enforce all vehicle traffic. But I can't imagine how courts will believe in the accuracy of them.
This is how Honda measured sound levels of their Goldwing's mufflers years ago and perhaps even today. An anechoic chamber that is dead-quiet inside is accurate. The devices the City bought are nothing less than suspect in accuracy. I assume almost all violators who receive tickets in the mail will pay them online. Because the City knows how reluctant people are to attend traffic court to challenge the charge.
