EN 20717-1 Acoustics - Odd Numbers for Sound Insulation in Buildings and Components - Part 1: Standard Test for Sound Insulation in Air

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 20717-1 testing. It defines odd number quantities for airborne sound insulation in buildings and building elements such as walls, floors, doors and windows.

It takes into account the different sound level spectra of various noise sources, such as noise sources inside the building and traffic outside the building.

Single digit quantities according to EN 20717-1 are designed to rate airborne sound insulation and to simplify the formulation of acoustic requirements in building codes. An additional odd number evaluation is specified in 0,1 dB steps for the expression of uncertainty (excluding spectrum adaptation terms). The required numerical values ​​of odd-numbered quantities are determined by changing needs. Odd number quantities are based on the results of measurements made in one-third octave bands or octave bands.

For laboratory measurements according to ISO 10140, odd-numbered quantities should be calculated using only one-third octave bands. The grading of measurement results performed in an extended frequency range is discussed in an appendix.
