Direct Sound through various fresh air vents and its impact on accommodation quality (English)
Abstract [en]

A survey is conducted to link sound reduction index with human experiences, the survey shows that the majority of residents value silence in their homes. About one in five residents hear that sound enters their home via the fresh air vents and is willing to pay for a soundproof fresh air vents. The results of the calculations indicate that the reduction index for the measurement object is 29 dB which means that the reduction rate will be 36.6 dB after installation of soundproofed fresh air vent. When switching to a soundproof air vent, an increase of 7,6 dB in sound reduction index is achieved. By providing more information to customers about different air vents with regard to acoustics, knowledge of the subject increases and they can actively take a stand to improve their quality of accommodation. 

Abstract [sv]

En enkätundersökning genomförs för att koppla teoretiska värden på reduktionstal till mänskliga upplevelser. Undersökningen visar att majoriteten av de boende värdesätter tystnad i sin bostad. Cirka en av fem boende hör att ljud kommer in i bostaden via friskluftsventilen och är villiga att betala för en ljudisolerad friskluftsventil. Resultatet för samtliga beräkningar visar att det sammansatta reduktionstalet för väggkonstruktionen är 29 dB. Vid byte till en ljudisolerad friskluftsventil ökar reduktionstalet med 7,6 dB vilket innebär att det sammansatta reduktionstalet blir 36,6 dB efter installation av ljudisolerad friskluftventil. Genom att ge mer information till kunderna om olika friskluftsventiler med hänsyn till akustik ökar kunskapen kring ämnet och de kan aktivt ta ställning till att förbättra sin boendekvalité.
