Airborne sound insulation and graphical indices

Journal of Sound and Vibration, 1982
Abstract The use of graphical indices is interpreted as an approximate approach to the estimation of sound insulation performance of building elements. Differences of weighted sound pressure levels are considered as quantitative measures for subjective sound insulation. The indices considered are formed by shifting a reference curve until the highest

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.

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 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.

Technical Note: Airborne Sound Insulation of Hollow Brickwork

Building Acoustics, 2007
This paper reports on the uncertainty of in situ measurements of the airborne sound insulation of hollow-brick walls in different housing plans, with emphasis on the influence of expansion joints. The mean and standard deviation of multiple measurements are obtained, which show significant differences in insulation values despite the fact that the same
