Introduction • Ólafur Daníelsson, M.Sc. Civil engineering. • Division manager – Acoustics and noise control in EFLA • Board member in IAS, Icelandic Acoustical Society • Member of EVHSC, Nordic Ergonomics of Voice, Hearing and Speech Communication – www.hearingthewords.com
Changes in the Icelandic building code • New building code was puplished early this year, and replaced building code nr. 441/1998. Regarding acoustics and noise control, the new building code refers completely to a new standard, ÍST45:2011. The ÍST45:2011 is a sound quality classification standard with classes A, B, C and D, where C defines the minimum requirements for new buildings. • The difference between minimum requirements in 441/1998 and ÍST45:2011 is remarkable.
Icelandic Building Code 441/1998 • The old building code defined minimum requirements for several aspects of acoustics in buildings, that is airborne sound insulation, impact noise level, noise level from various equipment and reverberation time.
