Uncertainty determination of in situ airborne sound insulation measurements

Applied Acoustics, 2015
Abstract In building acoustics the measurement uncertainty of sound insulation measurements is traditionally either not reported or reported as stated in the corresponding standard ISO 12999–1:2014. Determination and application of measurement uncertainties in building acoustics — Part 1: Sound insulation (former ISO 140-2).

Effects of thermal insulation on the airborne sound insulation of AAC masonry walls

Ce/Papers, 2018
AbstractInsulation systems change the acoustic properties of solid walls. A thermal insulation can have positive or negative effects on the airborne sound insulation. The behavior of heavier walls (e.g., calcium silicate bricks or clay bricks) is very well documented.

Airborne sound insulation referred to the ‘A’ weighting curve

Applied Acoustics, 1973
Abstract The ‘A’ weighting curve, drawn from the 56 dB datum, forms a very good compromise between the British House Party Wall Grade curve, and the International Standard Organisation R 717 reference curve. Since the ‘A’ weighting curve is already internationally standardised for noise measurements, its adoption as a reference curve for sound ...

The airborne sound insulation of glass: Part 1

Applied Acoustics, 1971
Abstract This paper is to be published in three consecutive issues of Applied Acoustics . This first part is a brief survey of the theory and practice of the measurement of the sound insulation of glass. In Part 2 the effects of changes in the various parameters will be discussed.

Analysis of Predictive Calculation Methods of Airborne Sound Insulation

Applied Mechanics and Materials, 2016
Acoustic properties of building structures are currently very actual theme with regard to the development of new building and insulating materials, while the methods for estimating the airborne sound reduction index evolve mainly from the second half of the 20th century.

A new method for auralisation of airborne sound insulation

Applied Acoustics, 2013
Abstract Auralisation techniques have quickly grown in popularity during the last few years, mostly due to their application in virtual reality, the gaming industry and room acoustics. The application of auralisation to sound insulation has also become a valuable tool to assess the sound insulation of buildings, and to suitably describe to the non ...

Group subjective ratings of airborne sound insulation

The Journal of the Acoustical Society of America, 1999
This paper will compare various sound insulation measures as predictors of the grouped subjective ratings obtained from a field survey of 600 subjects and the airborne sound insulation of their 300 party walls. The subjects lived in both row housing and multi-floor apartment buildings in three different Canadian cities.

An Alternative Method for Measurement of Airborne Sound Insulation

Building Acoustics, 2001
A method for determination of the transmission coefficient from Complex Modulation Transfer Functions CMTF:s based on measured impulse-responses is shown. In the method a separate measurement of the equivalent sound absorption area is not needed in contrast to in the standardised measurement.
