Description
Summary:Previous findings indicate that continuous low-frequency noises at moderate sound-pressure levels do not produce decrements in vigilance performance. Such noises are commonly found in urban environments, however; and it is important to explore their effects carefully. This study employed 27 human males in a numeric monitoring task to evaluate the effects of low-frequency (11.5 to 350 Hz) noise at moderate sound-pressure levels (80 db). More numeric signals were missed during noise than during control runs. The effect was small but statistically reliable (P < .033), in disagreement with previous research. The possible environmental impact of these findings is discussed.
