Abstract

Auditory interference scenarios, where a listener wishes to attend to some target audio while being presented with interfering audio, are prevalent in daily life. The goal of developing an accurate computational model which can predict masking thresholds for such scenarios is still incomplete. While some sophisticated, physiologically inspired, masking prediction models exist, they are rarely tested with ecologically valid programmes (such as music and speech). In order to test the accuracy of model predictions human listener data were required. To that end a masking threshold experiment was conducted for a variety of target and interferer programmes. The results were analysed alongside predictions made by the computational auditory signal processing and prediction model of (Jepsen et al. 2008). Masking thresholds were predicted to within 3.6 dB root mean squared error with the greatest prediction inaccuracies occurring in the presence of speech. These results are comparable to those in (Glasberg and Moore 2005) for predicting the audibility of time-varying sounds in the presence of background sounds, which otherwise represent the most accurate predictions of this type in the literature. © 2013 Acoustical Society of America.
