“…Based on earlier reports [14,15] that Zwickers' Loudness is an adequate quantity to be used for the perceived loudness of sound transmitted through walls in the framework of airborne sound insulation assessments, this quantity has here been used to compare the adequacy of existing and newly conceived single number quantities for airborne sound insulation. Two different emitting sounds (pink noise and newly proposed indoor noise) were filtered through 40 different lightweight, heavyweight and combined walls, and the Zwicker's Loudness values of the transmitted sounds were calculated.…”

“…As reported by Hohmann [15], A-weighting was based on an early version of the 40-phon equal-loudness-level contour, as defined by Fletcher and Munson [16]. It should be noted that, for the calculation of single number quantities, it seems reasonable to use a moderate loudness level as reference, considering that proper sound insulation should ensure low to moderate sound pressure levels in the receiving room.…”

The development and validation of single number quantities that are meant to serve for straightforward assessment and comparison of airborne sound insulation properties of partition walls are typically challenged by the necessity to perform large numbers of laboratory listening tests with human subjects. This is because a reliable validation of a single number quantity requires testing for many different wall types with multiple real-life stimuli that are representative for daily life soundscapes. In this article, an alternative approach is presented that allows to test a large number of “partition wall – real-life sound stimuli” combinations. This approach uses the well-established and nowadays generally accepted Zwicker’s Loudness for quantifying the subjective loudness of sound passing through a wall, and derive from that the subjectively perceived sound insulation. Using the proposed assessment method, the adequacy of single number quantities that are currently in use, and a number of newly proposed single number quantities, are compared.
