Culturally appropriate sounds are important elements of the national park experience in many parks. The Service will preserve soundscape resources and values of the parks to the greatest extent possible to protect opportunities for appropriate transmission of cultural and historic sounds that are fundamental components of the purposes and values for which the parks were established. Examples of appropriate cultural and historic sounds include native drumming (at Yosemite National Park, for example), music (at New Orleans Jazz National Historical Park, for example), and bands, marching, cannon fire, or other military demonstrations at some national battlefield parks. The Service will prevent inappropriate or excessive types and levels of sound (noise) from unacceptably impacting the ability of the soundscape to transmit the cultural and historic resource sounds associated with park purposes.
