Abstract

Svakodnevna izloženost različitim oblicima buke naročito je izražena u zračnom prometu, čiji su dio i helikopteri. Bitna obilježja helikoptera jesu visoke razine unutarnje i vanjske buke te let na malim visinama u naseljenim područjima. Dugotrajna izloženost buci kod pilota ili putnika u kabini helikoptera kao i kod pasivnog promatrača u blizini helikoptera dovodi do znatnog narušavanja kvalitete komunikacije te oštećenja sluha. U ovom diplomskom radu prikazani su i analizirani rezultati... More mjerenja vanjske i unutarnje buke helikoptera EC 135 na osnovu kojih je proračunata razumljivost govora u kabinskom prostoru putem SIL i SII metode. Less

Abstract (english)

Daily exposure to various forms of noise is particularly expressed in air traffic that helicopters are part of. Important characteristics of helicopters are high levels of cabin and outside noise and low altitude flight in populated areas. Long-term exposure to noise as a pilot or a passenger in the cabin of helicopter or as a passive observer in the vicinity of helicopter can lead to significant interference with communication and hearing impediment. This research shows and analyses... More the measured results of helicopter EC 135 cabin and outside noise levels which were used for the speech intelligibility calculations via SIL and SII methods.
