Spread of sound pressure on a tractor JCB Fastrac
RYŠAVÝ, Tomáš
The aim of the bachelor thesis is to determine the way how noise spreads from a tractor, noisiness at operator during different operations and then to enumerate equivalent sound-pressure level. The tractor JCB Fastrac 2170 was used for measurement. The first part of the thesis introduces the noise issue, noise of tractors, and then the development of Fastrac tractors. The next part of the thesis shows measured values of the observed tractor in graphs. Then equivalent sound-pressure levels are enumerated from those measured values. In conclusion, these values are evaluated and compared.
