Perceived quality of speech degraded by wind noise: An assessment of sources of variability in a Web experiment

Iain Jackson


An online speech-in-noise task was used to assess the effect of wind noise degradation on perceptions of audio quality. Many researchers in experimental psychology are increasingly confident of the potential of web-based tasks of perception and cognition. Investigations of the perception of audio quality, however, require consideration of additional factors (e.g. different reproduction systems) which may contribute to variability. Here we report analyses of potential sources of variability, in self-reported categories by participants pre-test. These categories are participant age, audio expertise, method of audio reproduction and level of background noise in the testing environment. Some effects on quality ratings were found but, overall, effect sizes suggest these were small relative to the effect of the main experimental variable of wind noise.
