Noise Effects on Passenger Communication in Light Aircraft 770446

This paper considers the effect of noise on conversation between two persons seated in a close, side-by-side position such as in a small aircraft. Twelve pairs of subjects were required to converse while being exposed to noises of various levels and spectra similar to those currently found in general aviation aircraft.
After a period of noise exposure, subjects rated the disruptive effect of the noise on conversation and judged the acceptability of the noise. Subjective estimates of the maximum times for pleasant conversation in the noises were also obtained.
