Sound ecologist Amara Velez created Harbor Dawn, an installation combining bird recordings made at an urban estuary. Some recordings include the rumble of nearby ferry engines. Because digitally removing this noise would also alter parts of the birds’ calls, Velez left the recordings largely unchanged. A critic claims that Velez’s main goal was to help visitors recognize how different bird species divide the estuary’s acoustic space by using distinct pitches and rhythms. According to the critic, Velez therefore selected recordings that clearly demonstrated these differences even when mechanical noise was present.
Which quotation from a visitor would most strongly support the critic’s claim that Velez achieved her goal despite the mechanical noise?
