ABSTRACT
This paper analyzed the effects two modern signal detection approaches. The first one is Analysis of signal detection in two senses and the second one is effect of content in Maskers. The analysis was based on Signal Detection Theory, which analyzes humans’ ability to discern between signals and noise. In conclusion, recent studies have shown that, when the effects of the masker are taken into consideration, visual and auditory signal detection have certain similarities. They both, for instance, cover the fundamental characteristics that signal detection theory suggests. Also, they both need the assistance of selective attention to complete the signal-detecting process. Additionally, the masker's content affects the detecting process when it comes to auditory signals. The findings of this paper had implications for video production, where careful selection of background music can enhance speech clarity in a video, and pedestrian safety in the field of setting the environment around the traffic.
