This web seminar will provide an introduction to the characteristics of sound waves, human perception of sound, sound and vibration measurements, measurement facilities, and various noise sources and noise control principles. It will include an overview of sound pressure, power, intensity, decibels, and frequencies. Practical examples will be used to familiarize participants with the acoustic fundamentals for solving noise and vibration problems and the associated solution principles.

Learning Objectives
By participating in this web seminar, you will be able to:

  • Discuss the differences of various acoustic terminologies that are important to solve noise and vibration problems
  • Define a relationship between sound pressure, sound power, and sound intensity
  • Associate decibel to both sound and vibration
  • Prepare effective acoustic specifications encompassing all variables that affect noise and vibration
  • Select correct instrumentation for noise and vibration measurements recognizing the challenges of measurements
  • Define the source-path-receiver relationship
  • Determine the steps of noise and vibration source identification process for a given application
  • Employ different noise control options to address specific noise and vibration issues

Who Should Attend
This fundamental web seminar will be especially valuable for technical staff, engineers, and managers with limited experience in noise and vibration. It is designed to be suitable for all areas of the mobility industry. An Associate degree in the field of science or technology is recommended; BS degree is preferred.

Registration Information
Registration for this live web seminar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access (at least 56K) and a telephone. The fee includes one connection to the 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 presentations, class session recordings, supplemental materials, and assignments.

Registrations will be accepted until 5:00 p.m. the day before the start of the web seminar, but early registration is encouraged to allow for pre-course set-up and instructions.

*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 web seminar. If your country is not listed, you may still connect using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).

Although WebEx Training Manager will automatically launch when you join the web seminar, you or your system administrator are encouraged to download the plug-in in advance to help ensure successful setup. Click here, then follow the onscreen instructions.

NOTE: The course presentation will be recorded and made available for 30 days to those who register by the deadline.

Multiple Seat Discount - Does your company have a group of employees who need this course? Register one individual at the appropriate member or list price, then register additional employees at half off the list price. Registration by phone with SAE Customer Service is required to take advantage of this discount. Register all individuals at the same time or mention the confirmation number for the first registrant. The offer is good for only the same web seminar offering. All registrants will receive a personal account and opportunity for CEUs.

Cancellations
Can't attend on the date/time above? The presentation will be recorded and made available for 30 days to those who are registered, regardless of availability for the live session. If you still need to cancel, transfer to a future offering, or designate a substitute, a full refund is issued if you notify SAE at least 14 days prior to the web seminar start date.
