Abstract

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.

Zwicker的响度模型作为一种稳健的计算方法来评估住宅隔墙的空气隔声描述符的充分性
开发和验证用于直接评估和比较隔墙的空中隔声性能的单数字量通常受到对人类受试者进行大量实验室听力测试的必要性的挑战。这是因为要对单个数字进行可靠的验证,需要对许多不同类型的墙壁进行测试,并使用多种现实生活刺激,这些刺激代表了日常生活中的声景。在本文中,提出了一种替代方法,允许测试大量的“隔墙-现实生活中的声音刺激”组合。这种方法使用公认的兹威克响度理论来量化声音穿过墙壁时的主观响度,并由此得出主观感知的隔音效果。使用建议的评估方法,比较目前使用的单数字数量和一些新提出的单数字数量的充分性。

期刊介绍: Acta Acustica, the Journal of the European Acoustics Association (EAA). After the publication of its Journal Acta Acustica from 1993 to 1995, the EAA published Acta Acustica united with Acustica from 1996 to 2019. From 2020, the EAA decided to publish a journal in full Open Access. See Article Processing charges. Acta Acustica reports on original scientific research in acoustics and on engineering applications. The journal considers review papers, scientific papers, technical and applied papers, short communications, letters to the editor. From time to time, special issues and review articles are also published. For book reviews or doctoral thesis abstracts, please contact the Editor in Chief.
