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
