N2  - Experiments concerning the effects of various configurations of background noise are reported. There appear to be two effects, one luminance-dependent which can be described in terms of an equivalent background luminance, and the other 'confusion' effect. The results are reported within ght framework of a theoretical model for noise. If a signal has an intensity adequate for daylight use then it is concluded that for the alerted observer the array of irrelevant lights of the kind found as a background to signal lights in the urban environment at night is unlikely to have a significant effect on its conspicuity.     <p>Language: en</p>
