| Abstract | This report gives the results of new listening tests to evaluate various airborne sound insulation ratings in terms of the intelligibility of transmitted speech. These subjective evaluations of sound insulation ratings are a first experiment of several intended to validate existing sound insulation ratings and investigate possible improvements. In these experiments listeners heard test sentences played through 20 different simulated walls in the presence of a constant low level ambient noise. The mean intelligibility scores from 15 subjects, each listening to 5 different sentences for each wall, were used to test the suitability and accuracy of various sound insulation rating measures for speech sounds. |
