The purpose of this session is to describe solutions for weight savings, which is a well-known strategy for improving fuel consumption in vehicles, and to explain the NVH impact of these weight reductions. Weight savings can come from interior and structural parts of vehicle in the form of one of the following solutions: composite materials, light weight alloys, aluminum & magnesium versus steel, bonding dissimilar materials, new damping compounds, elimination of mass barriers, higher performance acoustical products, reduction of part weight, reduction of part size, material substitutions, or reduced complexity of parts. NVH countermeasures for these weight reduction solutions will be outlined so that lightweight design for next generation vehicles can be implemented with attention to noise and vibration throughout the vehicle.

This workshop will present a practical introduction to SEA Modeling and its use in vehicle applications. A brief introduction to SEA will be followed by a broad spectrum of SEA models applied to vehicle acoustic design. Three distinct applications will be presented. These applications extend from passenger vehicle and heavy truck to SEA applied to aerospace vehicles. This workshop is structured as an introduction to SEA especially for those with limited experience in vehicle acoustics modeling. It also provides an opportunity to establish technical contacts for continuing working relationships.

Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and "Fourier signals." What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a "user perspective" and rules of thumb will be given together with good methods to avoid large errors. After attending this session, a much better understanding in regards to pitfalls and proper methodology will be the outcome.

The Structure Borne NVH Workshop continues with the same lecture team since inception in 2003. If you are still fuzzy about the new ideas you’ve seen, or from the hospitality suites the nights before, we have our new Thursday morning opportunity to root you in the fundamentals of Source-Path-Receiver Principles. A refined theoretical foundation covers the basics of low-frequency NVH , below 100 Hz, and mid-frequency, up to 500 Hz with guidelines for performance achievement. Recent advances in NVH Computer Aided Testing and Simulation will be reviewed drawn from the latest research efforts.

Silencer and muffler design is primarily accomplished via cut-and-try approaches in many industries. Noise issues are identified close to production and mufflers are designed and tested. In this workshop, a design process for mufflers is recommended. The steps that may be taken during the 1) clarification of task, 2) conceptual design, 3) detailed design, and 4) prototyping phases are outlined, and the process is demonstrated at each step for a cross-flow type muffler. It is shown that plane wave analysis is especially valuable in the conceptual design stage whereas numerical simulation is of greater value in the detailed design stage. Basics and tips for both plane wave analysis and numerical simulation are discussed. Measurement of transmission loss using the two-load method will be described and demonstrated using a transmission loss test bench.

The purpose and orientation are to empower engineers to recognize and fully connect their innate hearing capabilities with interactive analytic tools to characterize, design and improve mobility-product sounds considering human perception. An overview differentiates sound quality engineering from general acoustics as historically practiced, introduces the scientific field of Soundscaping, and provides a thought-context for productive work. “Ear training” examples will be included for recognizing sound characteristics such as modulation, tonality not caused by pure tones, and various types, scales and superpositions of time-dependence. The workshop illustrates and trains the approach to issues by linking perception with technical measurements, including both conventional and psychoacoustic tools. As always, a CD of the presentation will be given out at the close of the Workshop.
