Park sound management must limit audibility, not just sound level.

Evidence

Limiting the “audibility” of inappropriate sounds seems the major mission in conserving the wilderness of parks. The concept of audibility should be considered not only from a human point of view but also from the animals’ point of view, and the threshold of audibility could be quite different and difficult to assess species by species. — Almo Farina, Soundscape Ecology, 2284
