Historical Perspective on Vehicle Interior Noise Development 2003-01-1518

Over the years different methods of vehicle interior noise development have been used by car companies. During my 38 plus years of experience with General Motors' Noise and Vibration Laboratory and Advanced Vehicle Development Center, I have worked with varying methods, and when looking back, these methods have fluctuated between the application of highly subjective analysis and highly objective analysis.
Stepped up efforts to reduce overall vehicle engineering design and development time have intensified the use of computer modeling techniques. Iterations of acoustic package content proposals once done experimentally can now be accomplished, to some degree, with computer analysis. To achieve appropriate sound1 character that meets consumer expectations will require both subjective analysis and objective testing and analysis early in a vehicle program.
