The major noise sources are considered together with the noise generation mechanisms involved and approaches for reducing or suppressing the generated noise. Important basic advances in engine noise reduction technology were made in connection with the NASA Quiet Engine program. The prospect for reducing the noise levels of future aircraft below that of the new wide-body jets is good. However, a significant penalty in the form of increased cost to the traveler is also to be expected as the aircraft noise levels are gradually decreased.
