The main aim is to increase soil awareness in the general population as well as among decision-makers involved in soil policies and food producers. While moving through or digging the soil matrix, the soil fauna produces noises. Moreover, some animals seem to use the soil as a communication medium, forming a complex soundscape. Land use and agricultural management may have marked effects on the soil soundscape. Thus, the (acoustic) richness of a local soil animal community may serve as an indicator of the functioning of a soil ecosystem. In the scientific module of the Sounding Soil project, we implement and test acoustic indices to assess soil biodiversity and community composition. In the art and citizen science module, several Swiss farmers and subsequently the broader public record the soundscapes of their soils with a low-cost recording device. The result is a sound art installation as a publicly accessible observatory, integrating our scientific findings with recordings by participants in the citizen science module. This article describes the character of soil soundscapes in agricultural land and forests and reports on our research design and first insights into the relations between land use, soil types, biodiversity, and soil soundscapes.</p>

Tidal activity is an important driver of marine mammal behavior on foraging grounds, but is often omitted in studies of acoustic ecology. To better understand the role of sound in this vocal species we investigated the influence of tidal height and direction on humpback whale nonsong calling behavior in Frederick Sound and described new call types for this population. The likelihood of detecting a call from the low‐frequency‐harmonic, pulsed, or noisy‐complex call classes was independent of tidal activity. The likelihood of detecting a call from the tonal call class, and a feeding call in particular, was 2.1 times higher during flood tides than during ebb tides (95% CI 1.1&ndash;4.4). This likely reflects an indirect relationship between humpback whale foraging and tides.</p>
