6 Hours

Who Should Attend
This webinar is ideal for those want to understand the root causes of
many diesel engine noise issues, and how to use this understanding to
better diagnose and control diesel engine-related noises.

Prerequisites
Those intending to take this webinar should have at least a bachelor’s
degree in engineering, or equivalent, and be familiar with basic
engineering mechanics and vibrations.

Topical Outline

This webinar 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.

By connecting with this webinar, 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
