Abstract

ABSTRACT
The paper is focused on problematic of noise inside a fuselage of one propeller
aeroplane. The aim of this paper is to analyse the noise produced by engine located in
front of cabin for two passengers and also to show an application of specific
polyurethane as an insulation layer. There were a sound absorption coefficient; a sound
reflection coefficient and a sound pressure level are the most important of acoustic
values. The measurements were made in laboratory and in aeroplane. The final
interpretation depends on test results.
