Abstract

Buka je značajan faktor koji može utjecati na sposobnost pilota da obavlja svoj posao. Prekomjerna razina buke u kokpitu ili na pisti mogu pilotima otežati komunikaciju s kontrolom zračnog prometa i osobljem na zemlji, povećavajući rizik od pogrešne komunikacije i nesreća, stoga je bitno proučiti karakteristike buke i posljedice na zdravlje prekomjerne razine buke kojom su izloženi pilot zrakoplova. Prvih par poglavlja opisuje karakteristike buke i zvuka te opisuje posljedice na sluh i zdravlje osoba izloženim velikim razinama buke. Preostali dio rada opisuje helikopter kao izvor buke i tehničko eksplotacijske karakteristike helikoptera Bell 206B te metodu i postupak mjerenja s analizom dobivenih rezultata. Cilj ovog rada je izmjeriti i analizirati razinu kabinske buke helikoptera Bell 206B i procijeniti jesu li postojeće metode zaštite sluha dovoljne.

Abstract (english)

Noise is a significant factor that can affect a pilot's ability to perform his job. Excessive noise levels in the cockpit or on the runway can make it difficult for pilots to communicate with air traffic control and ground personnel, increasing the risk of miscommunication and accidents, therefore it is essential to study the characteristics of noise and the health consequences of excessive noise levels to which aircraft pilots are exposed. The first couple of chapters describe the characteristics of noise and sound and describe the consequences for the hearing and health of people exposed to high levels of noise. The remaining part of the paper describes the helicopter as a source of noise and the technical operating characteristics of the Bell 206B helicopter, as well as the measurement method and procedure with an analysis of the obtained results. The aim of this thesis is to measure and analyze the cabin noise level of the Bell 206B helicopter and evaluate whether the existing hearing protection methods are sufficient.
