Mobile walls: Rating of expected airborne sound insulation (NT ACOU 086)

Abstract

This Nordtest method specifies a method for mobile walls by which a relation is established between the airborne sound insulation measured in the laboratory and the airborne sound insulation to be expected in the field. The relation given presupposes that certain requirements have been fulfilled. In three informative annexes A, B and C respectively, a classification method, a guideline for the selection of sound insulation and an example of general acoustical guidelines on how to achieve good results are given.
