20.500.12556/DKUM-47001 Zasnova in konstruiranje komore za merjenje hrupa The design and construction of a chamber for measuring noise Magistrsko delo je nastalo v sodelovanju s podjetjem Doorson d.o.o., ki izdelujejo avtomatska drsna vrata za prehod ljudi. Magistrsko delo (v nadaljevanju naloga) obravnava podroben opis zasnove in izdelave komore za merjenje hrupa, s čimer si bo lahko podjetje v prihodnje pomagalo pri razvoju novih vrat za prehod ljudi, ki bi naj povzročala čim manj hrupa. Naloga spada v področje tehnične akustike, zato je v uvodnih poglavjih opisan zvok, kaj zvok sploh je, kako nastaja in kako se širi. Nato sledi predstavitev in opis gluhe, polgluhe sobe, odmevnice in cevi, ki predstavljajo različne vrste laboratorijskih testnih polj. V tem delu naloge je opisan tudi koeficient absorpcije zvoka, kako ga izmerimo in kaj nam pove. Glavni del naloge pa opisuje nastanek komore za merjenje hrupa. V tem delu je podrobneje opisano kako smo izmerili in določili frekvenčno območje ter spodnjo mejno frekvenco, potem kako smo določili dimenzije komore, zvočno izolacijo in kako je potekala izdelava celotne komore z vsemi pomembnimi elementi. Na koncu naloge so predstavljeni rezultati in razprava o le teh. The master thesis was created in collaboration with Doorson Ltd. which produce automatic sliding doors for the passage of people. The Master's thesis (hereinafter referred to as work) deals with a detailed description of the design and manufacture of a noise measurement chamber, which may help the company in the future in the development of new doors that cause about as little noise as possible. The work falls within the scope of technical acoustics. In the introduction it describes the sound, what sound actually is how it is produced and how it spreads. In further the work is followed by a presentation and description of anechoic and semi-anechoic rooms and reverberation rooms and tubes which present various laboratory test fields. Also in this part of the work the absorption coefficient is described, how it is measured and what he tells us. The main part of this thesis describes the development of the chamber for noise measurement. This part of the work describes in detail, how we have determined and measured the frequency range and the cutoff-frequency and how we determined the dimensions of the chamber, the sound insulation and how the production of the entire chamber with all the relevant elements has transpired. At the end of the work, the results and the discussion of those will be presented. : komora za merjenje hrupa gluha soba polgluha soba zvok vibracije akustika chamber for noise measurement anechoic chamber semi-anechoic chamber sound vibrations acoustics true true false [N.
