Abstract
Nakon subjektivne procjene da je buka helikoptera prekomjerna te da utječe na sigurnost letenja i zdravlje letačke posade, a do koje je došlo uslijed svakodnevnog obavljanja zadaća na helikopteru tipa Mi – 8 MTV-1, pristupa se detaljnijoj obradi teme unutarnje buke na spomenutoj letjelici u okviru diplomskoga rada. Cilj je rada ustanoviti razmjere učinka buke temeljem provedenih mjerenja i analiza. Kao uvod u tematiku, prvi dio rada donosi teorijske osnove neophodne za pobliže upoznavanje s temom. Drugi dio rada opisuje specifičnosti helikoptera Mi – 8 MTV-1 – njegove karakteristike, izvore buke kod tog tipa letjelice te mjere zaštite. Za potrebnu analizu izvršena su mjerenja unutarnje kabinske buke na samom helikopteru u letu po unaprijed zadanim režimima. Analizom dobivenih rezultata ustanovljeno je ima li buka doista štetan utjecaj, odnosno je li subjektivna procjena prekomjernosti buke ispravna.

Parallel abstract (English)
After subjective estimation of helicopter noise as being rather excessive and having an impact on flight safety and health of the aircrew, brought in the course of daily operations on helicopter Mi – 8 MTV-1, the topic related to the internal noise on the aforementioned aircraft has been thoroughly developed within the MA thesis. The aim of the thesis is to establish to what extent is the impact of noise based on the noise measurements and their analysis. The first part of the thesis provides theoretical background necessary for the topic introduction. The second part describes specifications of helicopter Mi – 8 MTV-1 – its characteristics, noise sources and protection measures. The measurements of the helicopter interior noise levels during the flight have been performed, based on criteria previously set. The analysis of the results identified whether the noise has the negative impact indeed, i.e. whether the subjective estimation of noise excessiveness is justified.
