Acoustics - Field measurement of sound insulation in buildings and of building elements - Part 1 : airborne sound insulation

<p>ISO 16283-1:2014 specifies procedures to determine the airborne sound insulation between two rooms in a building using sound pressure measurements. These procedures are intended for room volumes in the range from 10 m<sup>3</sup> to 250 m<sup>3</sup> in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the airborne sound insulation in unfurnished or furnished rooms where the sound field may or may not approximate to a diffuse field. The measured airborne sound insulation is frequency-dependent and can be converted into a single number quantity to characterize the acoustic performance using the rating procedures in ISO 717‑1.</p>
