DIN EN ISO 16283-1:2014-06

This part of ISO 16283 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 m³ to 250 m³ 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. This document completely supersedes EN ISO 140-4 as well partly EN ISO 140-5, EN ISO 140-7 and EN ISO 140-14. This test standard is directed at component manufacturers and independent test laboratories. The committee responsible for this standard is NA 062-02-31 AA "Schalldämmung und Schallabsorption, Messung und Bewertung" ("Sound reduction and sound absorption; measurement and evaluation") at DIN.
