Beyler yol sesi ve rüzgar sesi ile ilgili oldukça iyi bir yazı buldum ilginç olan notlarıda direkt ekledim.
Eminim çok ilginizi çekecek.

VW’s press release for its newest Golf (https://www.thetruthaboutcars.com/vw-offers-to-pay-taxes-on-journo-bribes/) calls ** "the quietest Volkswagen Golf since the model series began" characterized by "first-class acoustic properties." Yes, "a special sound-damping film in the windshield reduces driving noises, as does the newly developed seal design on the doors and side window guides."
Significantly less wind noise is generated by the outside mirrors due to their new shape. Furthermore, special modifications were made to better isolate the engine and passenger compartments from one another acoustically. Quiet rolling tires and new engine bearings round out the noise reduction program.
Empirically, the new Golf offers an improvement of 2 dB in three car generations and thirteen years.
Small cars have gotten much better, though. Corollas and Renaults used to be noisy boxes. Intense competition in the compact field seems to be working its magic. The Auris (the more-advanced, Euro-market Corolla) is a quite soothing small car, and the Megane’s low level of noise is a marvel.
You’d think advanced computer firepower, more precise manufacturing tolerances, double-lip door seals and multi-laminate windows, cars would generally be much quieter than in the 1990s. Why aren’t they? Remember one dirty secret of the car industry: usually, each successive generation of a car is cheaper to manufacture. Cost-cutting means that progress is slow—unless the market actively demands progress.
