Briefings

Curtin University and Taronga Conservation Society Australia researchers conducted the first hearing tests on Australian sea lions and long-nosed fur seals, identifying specific sounds these marine mammals can detect. The study aims to assess how human-made noise impacts these animals, though the findings are preliminary and subject to further validation.

Key points

• Researchers from Curtin University and Taronga Conservation Society Australia performed the first hearing tests on Australian sea lions and long-nosed fur seals.
• The study identifies specific sounds these marine mammals can detect, providing a baseline for assessing the effects of human noise pollution.

Context and limitations

The study is a preliminary assessment; results require further validation before they can be considered definitive.
