I’d say it’s a curve.
This could be log scale. Or inverse log idk which way you want the curve to be
dB is already log scale
Boring response: I mean, dB is calculated as a function of log, but when it’s on the X axis I imagine it’s typically displayed linearly
Funny response: loglog
meanwhile IQ is not linear or log

There is a house in my neighborhood with your picturesque suburban short king that has a white Chevy Tahoe with the loud muffler setup! As annoying as it is on performance cars, I kinda get it. But in a family SUV? Dumbest thing I’ve ever seen. And he revs it in front of middle school kids waiting for the bus to boot. What a sad little man.
Yea well those performance cars are also not street legal lol
Though I see a reason in there
If it’s on an SUV… Fuck off with your loud shit bro.
Also just loudness is nasty. The sound itself must be nice. If it’s not an H pipe I don’t want to hear that shit.
Deleting cats can be illegal depending on state but trust me there are plenty of legal, loud exhausts
I got an EV so that means i am the smart
I drive an EV, so I’m super smart! /s
you simply don’t understand
I’ve seen data from Austria indicating that 70% of vehicles exceeding legal noise levers are motorbikes, 20% are cars, 10% are trucks and busses. Vast majority of loud vehicles are modified in purpose to make more noise.
Also, loud vehicles will not pass annual technical checks so people put in legal exhaust for the check and then put the illegal, loud one in again. This has nothing to do with people not having money to fix their cars/motorbikes and everything with low IQ street racing sub-culture.
I wanted to be high IQ on this graph so I started walking everywhere. But I still have noisy exhaust.

I mean this is especially valid if you look at measured exhaust noise. Many people have cars that CAN make a lot of sound(if they use it for racing for example) but CHOOSE not to make a lot of sound to not ruin peoples days. The one big problem with this is that cheap motorbikes, which is something you would 100% use because theres no better public transit alternative, are also really loud.
But the whistles go WOO WOOOOOO!
Doesn’t apply to some rockets. NASA vs Space Sex rockets.
Sound pollution is a legit thing.
Yes, and it’s really bad for people: https://www.theguardian.com/environment/2025/jun/24/noise-pollution-harms-health-of-millions-across-europe-report-finds
I don’t think dB is a linear scale, so it would be weird if it increases in step with IQ dropping.
As sound pressure levels increase exponentially, perceived loudness increases linearly. That’s why the dB is used.
Sound is annoying but exhaust in general sucks. One thing that was amazing around april or may of 2020 was how clean the air smelt for a brief time.
2021 was a cyclist’s dream. Clean air and no cars
and everyone was instructed to give you at least 10 feet of distance :)
Related: “A new study by Western University in Ontario says that if you’ve got a car with a modified exhaust system, odds are you’re a guy and probably also psychotic and sadistic.”
https://www.caranddriver.com/news/a60983144/study-loud-exhaust-psychotic/
A few (major) caveats:
- The study is being filtered through a blog post (which isn’t even accurate enough to get the source of the paper correct, attributing it to “Western University in Ontario”).
- The study itself is written by one author and published in a journal by the University of Gdańsk of little import. That’s, of course, just an indicator it might not be the most credible.
- I will defend psychology as a science until I’m blue in the face, but it is right now undergoing a serious replication crisis, especially because of its poorly representative sampling.
- The sample is: “A sample of 529 (52% men) undergraduate business students”, which is a laughably biased sample compared to a global population. They never say which university, but given the publication and the author’s workplace, it’s safe to revise that to “529 (52% men) undergraduate business students at U. Gdańsk”.
- The study evaluates negative personality traits based off a “dark tetrad”, which is a still-controversial extension of the “dark triad”.
- As the author notes, the mean score from the three questions pertaining to “I want to fuck my car” wasn’t all that high (approximate average of “somewhat disagree” on all three with approximate standard deviation of a single “neither agree nor disagree”). This means the actual sample of people who had the problem being addressed in the title of the study was vanishingly small.
This, to me, is flimsy evidence at best even when I already buy into the basic premise.
Thank you for this! I was not familiar with all these shortcomings when I shared that study. I will not share it in the future.
Not true. I don’t have a modified exhaust system.
this whole post should be in fuck_motorbikes
