Sound Package Materials for Vehicle Noise Control Webinar
| October 5-28, 2010 (10:00 a.m. - 11:30 a.m. ET ) - via telephone/internet |

This webinar will be presented in eight, 90-minute sessions.
Selection of acoustical materials for vehicle noise reduction requires an in-depth understanding of vehicle noise, noise propagation, and the noise control properties of acoustical materials. This webinar will provide a detailed analysis of three different acoustical materials, namely absorber, barrier, and damper, how they are different from each other, and acoustical properties that materials should possess for optimum vehicle noise control. Participants will also learn ways to evaluate the acoustical performance of these materials using different test methods. Although the illustrations are from vehicle applications, the fundamentals of this webinar are applicable for nonautomotive applications as well.
Learning Objectives
By connecting with this webinar, you will be able to:
- Recognize various types of noise problems and noise paths in a vehicle
- Identify types of acoustical materials
- Describe ways that acoustical materials work and how they differ from each
other
- 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, supplying, and/or manufacturing noise control treatments and parts, this webinar will also benefit those with responsibilities including the areas of manufacturing, design, engineering, process, noise and release engineering, supervision or management. Participants should have an undergraduate engineering degree and a working knowledge of noise control and automotive acoustics.

The fee includes one connection to the 90-minute conference calls (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the webinar presentations, class session recordings, supplemental materials, and assignments.
*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this webinar. If your country is not listed, you may still connect to this webinar using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).
NOTE: The live course presentation will be recorded and made available for 30 days to those who register by the deadline but are unable to attend on the date/time listed above.
Multiple Seat Discount - Does your company have a group of employees who need this course? Register one individual at the full member or list price, then register as many additional employees at half off the list price. To receive the discount, register all individuals at the same time or mention the confirmation number for the first registrant when calling SAE Customer Service. The offer is good for only the same webinar offering. All registrants will receive a personal account and opportunity for CEUs.
Registrations will be accepted until 5:00 p.m. the day before the start of the webinar. A full refund is issued if you notify SAE at least 14 days prior to the webinar start date. If canceled less than 14 days prior, the full fee is charged. Canceling may reduce group or multi-webinar discounts. For the SAE Member registration fees, member dues must be current. NOTE: SAE reserves the right to cancel webinars and cannot be held responsible for related costs incurred by registrants other than the registration fee.
