Reaction time to the onset of a 1-kHz tone against a background of continuous noise was investigated. Results showed reaction
time to decrease with increasing tonal level, even when the signal-to-noise ratio was held constant, implying that Weber’s
law does not hold for reaction time to a tone in noise. When the reaction times were plotted against the loudness of the tone,

time to a sound is a simple function of its loudness. It is concluded that reaction time processes differ from the processes
involved in loudness discrimination or in signal detection.
