Vehicle Sound Package Materials Webinar
I.D. # WB1204 Duration 8 Hours
This four-session webinar provides a detailed understanding of the source ¿ path-receiver relationship for developing appropriate sound package treatments in vehicles, including automobiles, commercial vehicles, and other transportation devices. The webinar provides a detailed overview of absorption, attenuation (barrier), and damping materials and how to evaluate their performances on material, component, and vehicle level applications. A significant part of this course is the case studies that demonstrate how properly designed sound package materials successfully address vehicle noise issues.
Learning Objectives
By connecting with this webinar, you will be able to:
  • Identify various descriptors that are used in acoustics while working with sound package materials
  • Identify three fundamentally different sound package materials that are used in the industry
  • Explain how these materials work and how to improve their performance
  • Describe how various measurements are made and why they are necessary on a material level, component level, and vehicle level
  • Prescribe appropriate sound package materials for specific NVH issues
  • Construct proper protocols for combining different sound package materials for different components so that the final vehicle meets the required acoustic target
Who Should Attend
This webinar will be especially valuable for those new to the vehicle sound package area and those interested in how absorbers, barriers, and dampers work, how they are different from each other, how they interact with each other in an application, and what one needs to be aware of while making measurements so the results are meaningful. The webinar is also designed for OEM or supplier engineers and those in roles involved with design, evaluation, trouble-shooting, procuring, releasing, supplying, and/or manufacturing noise control materials and parts for passenger cars and light trucks, heavy trucks, off-highway vehicles, farm machinery, and other transportation systems including aircraft, watercraft and rail transit. An undergraduate degree and familiarity with basic acoustics and vibration, or acoustical materials would be beneficial.
