APUs and GPUs provide essential service to aircraft during ground operations. Sound levels near these devices range from 80 to 87 dBA at 30 m for APUs, 83 to 103 dBA at 10 m for turbine-engined GPUs, and 71 to 80 dBA at 10 m for piston-engined GPUs. Procedures are provided for: (1) estimating community sound levels due to APUs and GPUs, (2) estimating their exposures in terms of day-night sound levels, and (3) assessing the desirability of noise abatement by comparison to recommended levels for acceptability. Noise abatement options include: operational changes, equipment movement, equipment substitution, equipment quieting, and sound barrier usage.
