Sound Package Materials for Vehicle Noise Control
I.D. # 92032 Duration 2 Days
The sound package materials for vehicle noise control seminar provides a detail and thorough analysis of three different classes of acoustical materials ¿ namely absorbers, barriers, and dampers, how they are different from each other, and acoustical properties that materials should possess for optimum vehicle noise control. The seminar addresses new advances in acoustical materials, primarily in absorption materials that impact the vehicle acoustics. The seminar covers ways to evaluate the acoustical performance of these materials using different test methods, including material, component, and vehicle level measurements. The two day seminar starts with the fundamentals of NVH and sound quality related to sound package materials and discusses the importance of various noise sources that impact the development of sound package treatments in a vehicle.

Learning Objectives
By attending in this seminar, you will be able to:
  • Identify various descriptors that are used in NVH and sound quality while working with sound package materials
  • Recognize various noise sources and paths in a vehicle
  • Identify three different classes of acoustical materials
  • Describe ways that acoustical materials work and how they differ from each other
  • Road map for vehicle sound package development
  • Distinguish test methods used to evaluate the acoustical performance of material
Who Should Attend
Designed for OEM or supplier employees responsible for various noise activities, such as design, evaluation, trouble-shooting, procuring, supplying, and/or manufacturing noise control treatments and parts, this seminar will also benefit those with responsibilities including the areas of manufacturing, design, engineering, process, noise and release engineering, supervision or management. Attendees should have an undergraduate engineering degree and/or a working knowledge of noise control and automotive acoustics.
