I'm taking an Auto Technology class at my nearby community college. I can receive extra credit for doing a presentation on a topic and because I hound my junior high daughter to take advantage ALL AVAILABLE extra credit opportunities at school, she is turning the tables on me and demanding I do the same with my night class.
I'm 50 and most of the people in the class are, not surprisingly, more than half my age. I like all the kids but MY GOD do they have some obnoxious exhaust set ups. I was also young and dumb once so I mostly understand but I thought I'd do a sort of public service presentation on what makes a car sound good as opposed to just being loud.
For this I thought I might elicit some of your help. I'd like to use the timbre of this 2800 race car that has been posted here before as an example of what sounds good.
Specifically, what do you guys hear that makes this car sound so amazing.
The first thing that strikes me is the intake noise from the ITBs. There's also a wonderful balance between the bass, middle, and higher frequencies to my ear but I don't know if that is the correct way to describe it. It sounds “throaty" at low rpms but then starts to sound like an F1 car when it gets up in the revs. I love the sound it makes off throttle as well. I’m down for a car that pops and shoots fire as much as the next guy but there's something about the smoothness of that inline 6 off throttle that I just want to shot directly into my veins. And truth be told, I think the hillside location is adding a reverb that sounds almost ghostly as the sound continues to echo as the car moves out of frame.
What are you guys hearing? Feel free to be as specific and technical or impressionistic as you like.
