Abstract : The purpose of this experiment was to determine the combined effect of heat and noise on subjects performing an audio vigilance task, simulating the conditions of a helicopter cockpit. The task was to correctly extract specific aircraft heading changes from tapes of random aircraft radio transmissions. Additionally, the subjects were required to track the light of a pursuit rotor to simulate manual demands of helo flight. Experimental conditions combined three fixed levels of temperature, and three fixed levels of recorded helicopter noise. An analysis of variance of the results indicated no significant effects of noise, temperature, or their interaction, even at the .75 level. (Modified author abstract)
