NASA technology lets engineers see airframe noise.

The NASA Ames Research Center Moffett Field, Calif., is using computer imaging to application of mind preventable aircraft flight sounds. The research may eventually lead to the redesign and remanufacturing of airframe constituents like landing gear to quiet take-off and landings.
The novel test data provide critical visual information to aircraft designers be of importance toed about possible enforcement of stricter aircraft noise authoritys
"Some airports are imposing nighttime curfew upon noisy take-offs and landings, encouraging aircraft manufacturers to make quieter planes," says Paul
