This paper describes a group of experiments on the supposed effects of darkness and light on auditory sensitivity. The absolute threshold, differential threshold and masked threshold for a 1200 cyc./sec. tone, were measured in a total of forty‐six subjects, both when adapted to darkness, and to an ambient light of 25 ft.‐candles. There was a small, but reliable, improvement in both absolute and masked thresholds, in the light. No change was found in the differential threshold. Some introspective evidence was also obtained from twelve subjects.
