The Effect of a Tracking Task on Speech Intelligibility in Noise.

Abstract

The report describes an investigation which was carried out to study the effect on speech intelligibility in noise of simultaneously performing a tracking task. The results indicate that for some subjects there is a significant deterimental effect of tracking on speech intelligibility, and that this effect may be offset by improving the signal/noise ratios of communication. These results suggest that it is inaccurate to use data based on classical single-stress intelligibility tests in the design and assessment of communication systems to be used in multi-activity, real life situations.
