NOISE, VIBRATION AND HARSHNESS
Who Should Attend This academy will be especially valuable for engineers who ad- dress interior noise in the following types of vehicles: • Passenger cars
DAY THREE • Sound and Vibration Sensors −− Microphones
−− Intensity probes −− Accelerometers −− Laser vibrometers • Sound Level Meters and Analysis −− Types of sound level meters −− A- and C- weightings −− Fast, Slow, and Impulse Responses
• Light trucks • Heavy trucks • Off-highway vehicles • Farm machinery • Small planes • Personal watercraft • Rail transit vehicles Topical Outline Pre-Academy
−− Octive-band analysis −− FFT spectrum analysis • Source-Path-Receiver System −− The noise system −− The noise control system −− Standards −− Squeaks and rattles - types and causes • Both tracks combined OEM Facility Tour (evening) DAY FOUR • Acoustical Materials and Test Methods −− Absorbers −− Barriers −− Case examples • Both Tracks Combined - Instrumentation Workshop/Demo (evening)
• The SAE Pre-Academy is a totally optional offering that in no way affects your participation in the SAE Vehicle Noise Control Engineering Academy. • The SAE Pre-Academy consists of 2-1/2 hours of web-based lessons that can be accessed at your convenience. These lessons provide an overview of basic sound and vibration concepts that are the foundation of noise control engineering. It is intended mainly for those new to the field of noise control, while providing a refresher for those more experienced in the field. In addition to the video lessons, a series of self- assessment questions are provided with solutions furnished upon request.
