Evaluating airborne sound insulation in terms of speech intelligibility

The Journal of the Acoustical Society of America, 2008
This paper reports on an evaluation of ratings of the sound insulation of simulated walls in terms of the intelligibility of speech transmitted through the walls. Subjects listened to speech modified to simulate transmission through 20 different walls with a wide range of sound insulation ratings, with constant ambient noise.

Airborne sound insulation of thin walls

The Journal of the Acoustical Society of America, 1991
Approximate analytical solutions are presented for the transmission of airborne sound through a plate between two rooms. The rooms are placed above each other and are of different size. The area of the plate is larger than the area of either room. Simple formulas are derived from the Euler–Bernoulli plate theory for the transmission due to the forced ...

Airborne sound insulation as a measure for noise annoyance

Proceedings of Meetings on Acoustics, 2013
There is currently a lack of measure to describe airborne sound insulation in terms of subjective evaluation of noise annoyance. With a given sound insulation value, different kinds of sound signals could produce rather different hearing sensation levels.

Simulation and Auralization of Airborne Sound Insulation

2020
As previous chapters dealt with virtual environments with sound in free-field and in enclosures (room acoustics, Sect. 11.7), situations with partition walls and complete buildings will be discussed in this chapter. This concerns the field of classical building acoustics as part of architectural acoustics.

The summary of techniques on the airborne sound insulation measurement

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
This paper indicates that there are some shortcomings in the traditional sound pressure method for sound insulation measurement, such as sound leakage, flanking transmission and the low signal-noise-ratio. And then the impulse and sound intensity measuring methods are introduced. The progress of the sound intensity methods is also illustrated.

An algorithm for auralization of airborne sound insulation

The Journal of the Acoustical Society of America, 1999
On the basis of a prediction model for airborne sound insulation (EN 12354-1), a signal processing tool was developed for auralization of indoor and outdoor noise in receiving rooms. For this purpose the direct transmission and four flanking paths were taken into account according to their one-third octave band data.

The airborne sound insulation of glass: part 3

Applied Acoustics, 1971
Abstract This paper has been published in three consecutive issues of Applied Acoustics. This final part consists of the author's conclusions and findings and the tabulated data discussed in Part 2. A considerable amount of information has been collected which was not previously available in one paper and some areas in which more information is ...

The airborne sound insulation of glass: Part 2

Applied Acoustics, 1971
Abstract This paper is being published in three consecutive issues of Applied Acoustics . In this second part, published results of sound insulation measurements are discussed in relation to the effects of the various factors. The tabulated data supporting this discussion will constitute the final part.

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 ...

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.
