This  International  Standard  specifies  a  laboratory method  (clause  6)  and  in  situ  methods  (clause  7)  for the  determination  of  the  sound  insulation  performance of  sound-protecting  cabins.  The  sound  insulation  per- formance  is  the  reduction  in  sound  pressure  level  or sound  power  level  afforded  by  the  cabin.  The  methods are  applicable  to  cabins  with  a  small  leak  ratio (e  s  2 %).
