Anderson, G S; Horonjeff, R D

The report summarizes that literature review, discussing sound divergence, atmospheric absorption, attenuation due to intervening hills and heavily wooded areas, soft-ground attenuation, and the acoustical descriptors that are of potential concern to the Park Service as the aircraft flies by. Finally, the report concludes with a summary of the effect of aircraft altitude upon sound levels on the ground, taking all these factors into account. Included in the summary is a discussion of the potential acoustical effectiveness of using altitude as a mitigation measure for any adverse effects of aircraft sound within the National Park System.
