abstract = "In Austria the standard for classifying sound insulation is {\"O}NORM B 8115-5. The building legislation regulates the minimum standard only by single number values in the standard frequency range without using spectrum adaption terms. The higher sound insulation classes have significantly
higher requirements for airborne and impact sound and this formulated in combination with spectrum adaptation terms including the extended frequency range. It seems to be necessary to explore the uncertainties of sound measurements in this context. This was done in an in situ round robin test
conducted in 2018, in which 20 laboratories participated. The measuring objects were chosen in a music school during summer holidays. The sound insulation between the measurement rooms is rather high because of the purpose for music exercise. The measurements had to be carried out according
to EN ISO 16283-1 and -2. The challeng due to the high sound insulation was the influence of the external noise and the uncertainty of the low frequencies. Planning, implementation and evaluation of the round robin test were carried out according to the ISO 5725 series. The results are presented
and discussed by their causes and consequences.",
