Briefings

Scientists at Australia Zoo conducted a hearing test on trained sea lions and seals to investigate the impact of human-made noise on marine mammals. The study involved trained subjects responding to auditory stimuli, providing data on how noise affects their hearing capabilities. This research aims to inform conservation efforts regarding noise pollution in marine environments.

Key points

• Scientists trained sea lions and seals to respond to auditory stimuli for a hearing test focused on marine mammal noise exposure.
• The study provides empirical data on how human-made noise influences the hearing thresholds of trained marine mammals.

Context and limitations

Data collection occurred in 2026, with results limited to trained subjects; broader population effects remain unquantified.
