Sound transmission through windows I. Single and double glazing

Abstract

The results of an extensive series of laboratory measurements of sound transmission throul windows are presented. By reference to these data, the systematic dependence of the sound transmission loss on glass thickness and interpane spacing is evaluated.

“…Figure 2. Overview of the measured insulation spectra of the façades/windows at all survey locations (thin lines), including an example of a standard insulation measurement of (single) 3-mm glazing and a double 3-mm glazing (without void space) (Quirt, 1982). Example photographs, taken from the front door of the respondent's dwelling, facing the street.…”

“…In addition, the thicknesses of the individual glazing panels and voids between 212 them play an important role (Quirt, 1982). Examples of a (standard) measurement of a single and 213 double glazing (Quirt, 1982) are added on top of the measured façade insulations. The measured 214 in-situ data gives somewhat lower insulations.…”

Investigation of transmission loss through double wall structures with varying small air gaps using modal analysis.

“…To extend the theory, numerous papers have been published describing the effects of the different variables that drive the performance of the double wall structures [4][5][6][7][8]. These variables are experimentally studied in the literature and include but are not limited to the thickness of the individual walls, material of the wall, thickness of the gap between walls, composition of the gap, stud locations, stud material and screw spacing [4,8].…”

“…There are studies that have investigated metal wall constructions including steel studs, and either steel or aluminum wall faces, but the focus on larger gap spacing has remained [4]. A few studies have been published regarding small gaps between double walls, concentrating on the performance of glass window applications [5][6]10].…”

“…Quirt followed with extensive experimental work comparing experiments with available theory and to determine the dependence of transmission loss on wall thickness and gap spacing [5]. Due to the study being concentrated on widow design, many of the experiments were conducted on double glass walls with small air gaps.…”
