Free motorcycle sound level test in Toronto on July 22nd.
- Thread starter cruiserider
- Start date
I like that they are trying to do this. The cynical side of me would keep me far away from that. Either I know my exhaust is pretty quiet and I will pass in which case the test is just a waste of my time or I know it is questionable and I can't guarantee that I am not volunteering for a ticket (or note attached to my plate).
If anyone really wants to know, I can run the test and I don't work for any government entity so no repercussions for the results.

There are many. The results can vary greatly based on app/phone/case/sound level/etc. You may have a good combination to conduct the measurement or you may have completely useless readings. Without comparing to a calibrated measurement, it is hard to know if your results were reasonable. Most of the apps are garbage for error trapping. For instance over ~120 dB, mems mics are useless as you are overloading the sensor, most apps continue to happily display numbers without a huge warning that you may be overrange. Same with measurements at lower sound levels where you can be measuring the noise floor of the system and not the device under test.
Stupid or incomplete notice. I'm sure they intend to test and then just caution anyone who's bike is louder than spec. Obvoiusly no one is going to show up with an illegal exhaust so they can be ticketed.
This might be of value for people who purchased a bike with a modified exhaust system and don't know if it is legal. If you have an unmodified exhaust then it's a waste of time.

It may have no involvement from TPS. This type of event could be entirely run by by-law staff. They may just be trying to help people learn the limits ( or alternatively, tell the loud bikes to stay out of toronto or expect a ticket). Their goal is less loud bikes in the city, so telling people to stay away is as effective as a ticket.

Does anyone other than TPS have the equipment ? It will be interesting to see who (if anybody) shows up.
When I was talking to Toronto staff before, the plan was by-law would hold/maintain/operate the equipment. They needed TPS assistance to conduct roadside checks as by-law doesn't have the power to stop vehicles. Doing a clinic removes the obstacle that required TPS involvement. The equipment isn't cheap, it is cheaper for by-law to own a kit or two and train a few by-law staff as that is a much larger percentage of staff than if you trained a few TPS officers.
It's on gov't owned land. Trying to do it at semi-organized meets on private property requires approval from more people many of whom are hard to get permission from. Now, if enough complaints were received, using cops and setting up a checkpoint at the parking lot exit could be an efficient scheme to process a lot of potentially offending vehicles.
The original standard contemplated multiple exhaust pipes. I don't know how Toronto is measuring them. I highly suspect they just measure at the documented position from one pipe. At the measurement position, for most multiple pipe bikes you will be 1 to 2 dB down over the same bike with a single pipe. I also suspect (but do not know) that they may be providing some leniency between test results and ticket. If you are within a few db, there is a reasonable potential for local environmental factors to influence the measurements. Similar to speeding tickets, if they allow a buffer over the official limit, that is much easier to prosecute.
I have never heard of a local municipality testing off idle. It just adds another layer of complication for the municipal staff. Also risk. If municipal employee has their hand on the throttle when something goes wrong, the owner has a path to money. Also path to victory in court, who says your tach is correct? If they use a sirometer, is that accurate enough to stand up in court? Testing at idle means municipal employees do not need to touch your bike.
