In open-plan offices, single screen barriers are widely used to separate individual workplaces as a means of improving acoustical privacy. In this paper, a general model for calculating the insertion loss of a single screen barrier in the presence of

In this paper proposed methods are compared through prediction of flanking sound transmission across a wood frame wall-wall junction. Data measured in the NRC-IRC flanking sound transmission facility is used as input data as well as for the validatio

Structural damping indicates the energy loss in materials and systems respectively. Hereby, different loss mechanisms must be distinguished: namely internal losses or material damping due to conversion of kinetic energy into heat and coupling losses

At NRC-IRC, a double leaf wall assembly has been tested with and without a constrained layer damper (CLD) to determine the improvement on the sound transmission loss (TL). In parallel, a Statistical Energy Analysis (SEA) model was derived to estimate

Low frequency impact sound is one of the most common reasons for complaints by buildingoccupants. Therefore, some countries, Japan and Korea, have introduced heavy soft impactsources into their standards ? the ?tire? and the ?rubber ball? - that effe

ISO 3382 describes a number of objective room acoustics parameters that are generally accepted as useful for rating some specific aspects of concert hall sound fields. They include measures of decay times, energy ratios, measures of sound strength an

This paper describes a new system` of speech privacy criteria in terms of Speech Privacy Class (SPC) values. SPC values can be used to specify the required speech privacy for new construction or to assess the speech privacy of ex-isting closed rooms.

One important issue in building acoustics is the testing and rating of the impact sound isolation of floor assemblies. Although the basic principal of impact testing is equal in all standardized test procedures - i.e. the test specimen is excited wit
