Ilmaääneneristävyyden suunnittelu ja mittaus oppilaitoskohteessa rakenne- ja taloteknisestä näkökulmasta

Abstract

Tässä opinnäytetyössä käsitellään ääntä, huoneakustiikkaa sekä ääniteknisten rakenteiden ja LVIStekniikan suunnittelua ja toteutusta osana rakennuksen ääneneristystä. Työssä tutkittiin lisäksi erilaisten seinärakenteiden ja LVIS-tekniikan yhdistämisen vaikutusta kokonaisilmaääneneristävyyteen. Työssä tutkittiin Karelia-ammattikorkeakoulun Tikkarinteen kampuksen D-talon terveydenhoitajan, psykologin, opinto-ohjaajan, kuraattorin, oppilaitospastorin tiloja sekä niiden välisiä odotustiloja. Lisäksi tutkittavana oli E-talon liikuntasalin ja fysioterapian opetustilojen välistä ilmaääneneristävyyttä sekä ilmaäänen vuotokohtia. Tutkittavissa tiloissa oli aiemmin suoritettu ilmaääneneristävyysmittauksia useampaan otteeseen, ja mittausten välillä on tehty D-talon tilojen välisten ovien tiivisteiden korjaustoimenpiteitä. Vuotokohtien kartoituksessa selvisi, että mm. D-talon ovien reunat vuotavat reilusti ääntä edelleen ja että tilojen välisen ilmaääneneristävyyden parantamiseksi tarvitaan vielä toimenpiteitä. Liikuntasalin ja fysioterapian opetustilan välinen lasiväliseinä vuotaa ääntä useasta eri kohdasta, osittain asennusvirheiden johdosta. Lasiväliseinä ei tämän tutkimuksen valossa sovellukaan ääntä eristäväksi seinärakenteeksi tämänkaltaisten tilojen välille.

In this thesis, sound and room acoustic were studied along with sound technic structures and HVACtechnology for designing and executing a building’s soundproofing. In addition, the effects of combining various wall structures and HVAC technology on overall airborne sound insulation were studied. For this thesis examined airborne sound insulation and sound leaks between rooms in Karelia University of Applied Sciences (UAS) Tikkarinne campus were examined. The examined spaces were Karelia UAS staff’s office spaces and waiting rooms connected to the offices in the D building. Also building E indoor gym was examined. Examinations were based on earlier airborne sound insulation measurements of the offices and indoor gym. Repairs to office doors were conducted between earlier airborne sound insulation measurements. Airborne sound insulation leak spot mapping showed that the office doors still leaked too much, and that more actions are needed to solve the problems in the airborne sound insulation between the spaces. The glass wall in the indoor gym leaks sound from multiple places. A part of this problem arises from incorrect installation. In the light of this thesis, the glass wall as a dividing wall in the indoor gym is not a correct structure between the spaces considering the use of the indoor gym and the surrounding spaces.
