Investigation of the physical driving mechanisms of wind noise in hearing devices by computational fluid dynamics

Scientific Reports
Wind noise impairs the functionality of hearing aids and hearables outdoors or during sports by interfering with communication signals. This study aims to visualize the wind noise generation patterns around the human head by validated scale-resolved flow

Drivers of physical connectivity between coral reefs along the Southeast African coastline

Scientific Reports
The resilience and persistence of coral reef metapopulations strongly depend on their dispersal potential. Larval dispersal influences the diversity and genetic structure of coral populations and contributes to population recovery following disturbances.
