This part of ISO 717<\/span><\/span>:<\/p>\n

    \n
  1. \n

    defines single-number quantities for impact sound insulation in buildings and of floors;<\/p>\n<\/li>\n

  2. \n

    gives rules for determining these quantities from the results of measurements carried out in one-third-octave bands in accordance with ISO 10140-3<\/span><\/span> and ISO 16283-2<\/span><\/span>, and in octave bands in accordance with that option in ISO 16283-2<\/span><\/span> for field measurements only;<\/p>\n<\/li>\n

  3. \n

    defines single-number quantities for the impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3<\/span><\/span>;<\/p>\n<\/li>\n

  4. \n

    specifies a procedure for evaluating the weighted reduction in impact sound pressure level by floor coverings on lightweight floors.<\/p>\n<\/li>\n<\/ol>\n

    The single-number quantities in accordance with this part of ISO 717<\/span><\/span> are intended for rating impact sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty (except for spectrum adaptation terms).The required numerical values of the single-number quantities are specified according to varying needs.<\/p>\n

    The rating of results from measurements carried out over an enlarged frequency range is described in Annex A<\/span>.<\/p>\n

    A method for obtaining single-number quantities for bare heavy floors according to their performance in combination with floor coverings is described in Annex B<\/span>.<\/p>\n

    Examples of the calculation of a single-number quantity is given in Annex C<\/span>.<\/p>\n

    A method for rating heavy\/soft impact sound insulation performance of building and building materials by A-weighted maximum impact sound pressure level is given in Annex D<\/span>.<\/p>\n","protected":false},"excerpt":{"rendered":"
