” The same way we might hear a specific song and experience a range of emotions, underwater speakers surprise researchers as unhealthy corals positively respond to their study. They placed underwater speakers to emit sound frequencies resembling what a healthy coral reef would sound like. Not only did this influence the unhealthy coral reefs to regenerate, but it also attracted a variety of fish to help reestablish degradation.
“We use loudspeakers to broadcast healthy soundscapes on experimental coral-rubble patch reefs for 40 days during a natural recruitment season (November–December 2017) on Australia’s northern Great Barrier Reef. We compare the developing fish communities on these acoustically enriched reefs with those on two categories of acoustically unmanipulated control reefs (with and without dummy loudspeaker rigs). We find that acoustic enrichment enhances fish community development within an important reef fish family, across a range of specific trophic guilds and at the level of the whole community,“ researcher Timothy A. C. Gordon mentions. ”
