, I mentioned how I got it acoustic dampened professionally. With so many used Model 3s being available on the market today, I thought it would be appropriate to update the article from February 2021 and run it one more time. Let me remind you that soundproofing can be a very subjective thing. Your driving environment, tires, surface, speed, and even hearing capacity can greatly influence the end result.
It’s important to note here that the gasoline-fed inline 5-cylinder internal combustion engine in the Volvo S40 gets a power stroke every 144 degrees with overlap as opposed to the power strokes of an inline 4-cylinder engine every 180 degrees with no overlap. Because the power strokes have less downtime in a 5-cylinder engine, it runs more smoothly than a 4-cylinder engine, but only at limited mid-range speeds.
“Unfortunately for you, that experience with the Volvo makes good sense. No matter how cool the Tesla Model 3 is, Volvo really has a good reputation for well-built and slightly ‘over engineered cars. We will do our best to limit the noise, but do not expect that we can remove everything. However, my colleague Alexander mentioned that he has experienced that the trunk ‘disappeared’ after the attenuation.
Alexander shows me the subwoofer speaker driver and I can see the cone is made of a paper fiber material, which is very normal, but this is where things can be optimized further. However, my hearing is not perfect after driving a dozen motorcycles over 3 decades, so I will save my money for the day I can buy a “tinnitus-canceling system.”
This is the kind of expenditure that is lost on the spot. The resale value does not increase when you do something like this. But I intend to spend a lot of time inside this car, and the difference I subjectively experience is very much worth the expense.
