Biological sound diversity is important in the health of coral reefs as biodiversity and sound diversity are directly related. Anthropogenic noise can create “acoustic fog” which masks biological noise, decreasing ecosystem resilience. This noise can directly influence the physiology and behaviour of marine organisms through acoustic interference as it interferes with larvae dispersion by masking habitat soundscapes. Although it is a significant factor in the health of corals, noise pollution has received little attention in coral reef conservation. Therefore, understanding of soundscape dynamics and associated mechanisms remains highly speculative due to insufficient spatiotemporal coverage and a lack of techniques for identifying distinct sound sources (Lin et al., 2023).

In addition to the effects of acoustic fog being speculative, there is also a very limited pool of species that have been tested. This means that there is little information available on the effects of and sensitivity to enrichment (Woods Hole Oceanographic Institution, 2024). Certain coral species could respond differently to acoustic enrichment, meaning that this tactic could prove insufficient.

Another issue is that larvae are very vulnerable and can be overgrown by algae, covered by sediment, predated upon, or for other reasons fail to reach reproductive age (Aoki et al., 2024). If larvae are unable to reach this age, reef regeneration will not be possible. This makes studying the effects of acoustic enrichment difficult as coral is a relatively sensitive species.

Additionally, restoration attempts can be extremely costly and must be planned thoughtfully, requiring knowledge of coral biology and marine ecology (Woods Hole Oceanographic Institution, 2024). These projects can range up from 400,000 US$/ha to 6,000 US$/ha for the nursery phase of coral gardening and 4,000,000 US$/ha for substrate addition (Bayraktarov et al., 2019).

Acoustic enrichment may not be sufficient enough for restoration on its own and should be complemented by chemical and light cues to ensure proper regrowth (Aoki et al., 2024). These cues help larvae to choose where to settle and begin growth. One study stated that with the assistance of cycloprodigiosin (CYPRO), settlement success was measured at about 90% (Fiegel et. al, 2025).
