Park noise sources fall into four intrusion categories

Evidence

Noise is a process that creates a growing concern for national parks and protected areas managers. External nonrecreational noise intrusions, external recreational noise intrusions, onsite interactivity noise intrusion, and onsite intraactivity noise intrusions are the four main categories of noise sources that have an impact on protected areas. — Almo Farina, Soundscape Ecology, 2459
