Metodika stanovení hlučnosti energetických strojů

Abstract

The bachelor's thesis discusses the methodology to determine the noise level of energy machines. In the introduction, it describes what sounds and vibrations are, how they occur, how they can be quantified by measurement and what is their impact on the environment. It will discuss the basics of how acoustic quantities are measured and what measurement standards are used in acoustics. And last but not least, it deals with the measurement itself, its methodology and the ways how to determine the emission of sound pressure. Based on the measurement, it is assessed whether the power machine meets the manufacturer's guaranteed noise regulations.
