BUILDING ACOUSTICS - ESTIMATION OF ACOUSTIC PERFORMANCE OF BUILDINGS FROM THE PERFORMANCE OF ELEMENTS - PART 1: AIRBORNE SOUND INSULATION BETWEEN ROOMS
10-05-2017
ISO 12354-1:2017 specifies calculation models designed to estimate the airborne sound insulation between adjacent rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements, and theoretically-derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in the frequency range 1/3 octave 100 Hz to 3 150 Hz in accordance with ISO 717‑1, possibly extended down to 1/3 octave 50 Hz if element data and junction data are available, the single number rating can be determined from the calculation results.
