Abstract
Overall and octave-band sound pressure and vibration levels were measured in two CC137 aircraft, one with a normal passenger configuration and one with a VIP configuration. The results indicate that the difference in interior configuration does not significantly affect the noise levels at equivalent passenger locations in the two aircraft. Engine noise is greatest at the rear of the aircraft, and noise produced by the air conditioning system (primarily air-flow noise from the PSU outlets) is maximum at row 11. The noise levels within the aircraft does not present a hazard to the hearing of crew members or passengers. Speech interference effects are considerable, however, especially in the area where noise from the air conditioning system is maximal.
