Tracing the Evolution of Sound in Six Generations of the Chevrolet Corvette

This study presents the noise characteristics of six generations of the Chevrolet Corvette, an iconic American sports car that has undergone technological leaps and design innovations over the years, redefining performance and handling. The research conducted as part of an undergraduate noise control project is meant to study the auditory experiences of drivers, occupants, and pedestrians, considering the implications of improved cabin noise reduction in newer models while examining the changes surrounding powertrain and exhaust expectations in various generations of the model. Focusing on the evolution of sound pressure levels, the study analyzes both interior and exterior sound pressure level data to extract insights into the acoustic metamorphosis of the Corvette. This exploration enhances the understanding of the difference between sound and the Corvette driving experience. The research's significance extends to the community of Corvette enthusiasts, contributing to the historical narrative of this sports car and impacting automotive culture. Anticipation regarding the exterior experience for pedestrians aligns with sentiments about the powertrain and exhaust personality. The study concludes that stock Corvettes, even older models, do not significantly endanger hearing, mainly due to road noise. The interior sound at various speeds and accelerations can reach close to 90dBA periodically. Also, aftermarket exhaust systems hint at the possibility of extremely high sound pressure levels.
