With the Co-Operation of 1,600 members of the public a series of aircraft noise assessment tests was made at the 1959 Farnborough Air Show to obtain further information on the way in which the perception of these noises is influenced by subjective effects. This provisional analysis shows that Beranek's empirical method for assessing the perceived noise level is adequate for the comparison of existing types of fixed-wing aircraft. A secondary part of the experiment, dealing with noise simulating the ducted-fan engine, is also described.
