Airborne sound insulation of new composite wall structures

Abstract

Abstract. Protection against noise is one of the essential requirements of the European Construction Product directive. In buildings, airborne sound insulation is used to define the acoustical quality between rooms. In order to develop wall structures with optimal sound insulation, an understanding of the physical origins of sound transmission is necessary. To develop a kind of knowledge that is applicable to the improvement of real walls and room barriers is the motive behind this study. The purpose of the work is to study the sound insulation of new composite wall structure.

Fifteenth Workshop Solar Influences on the Magnetosphere, Ionosphere and Atmosphere

“…The results show a very good coincidence between the model values and the measured ones in the conditions of the geomagnetic storm on 3-4November 2021 [Mukhtarov et al, 2021]. The obtained results confirm that the proposed dependency sufficiently accurately manages to solve the tasks set by the Ministry of Defense and the practical needs of environmental technologies [Ivanova et al, 2018].…”

Avaliação em campo do ruído aéreo de uma sala de aula tipo em campus universitário

“…Se tratando de edifícios, o isolamento sonoro de ruído aéreo é utilizado como parâmetro para definir a qualidade acústica entre os ambientes (IVANOVA et al, 2018). A norma ISO 16283-1 (2014) utiliza como parâmetro ponderado, no caso de avaliações de isolamento sonoro aéreo em medições em campo, para acústica de sistema de vedação vertical interna (SVVI) a Diferença Padronizada de Nível Ponderada (D' nT ), já a ISO 16283-3 (2016) adota para fachadas ou sistemas de vedação vertical externo (SVVE) a Diferença Padronizada de Nível Ponderada a 2 metros de distância da fachada (D' 2m, nT ).…”

A Study of Stress – Induced Subtle Magnetic Changes in a Mild Steel using Barkhausen Emission-Aided Analysis Approaches

“…Today, despite extensive and intensive theoretical and experimental investigations, [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], the applied stressinduced micromagnetic effects in ferromagnetic steels are complex and not yet fully understood. In general, the investigation of stress effects on polycrystalline ferromagnetic materials needs a basic reduction to a formulated set of problems solvable by detailed experimental investigations and/or mathematical analysis concerning the dynamics of domain wall motion.…”
