EDU Trainings s.r.o.
Popis kurzu
This course 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.
Objectives
By participating in this course, you\’ll 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
