Hear what our hydrophones capture
Three real-world recordings made with Burns AquaEar hydrophones in Australian waters. No equalisation or noise reduction applied — what you hear is real field performance.
Humpback whale vocalisations
Whale song recorded from a small vessel off Port Stephens. Demonstrates the full low-frequency response and clarity of the CR30‑40 in real ocean conditions.
Dolphin clicks & whistles
Navigation clicks and social whistles from bottlenose dolphins, recorded with the CR30‑40 at 1 m depth. Clear reproduction of the full cetacean audio range.
Dolphin pod — Port Stephens
Resident bottlenose pod recorded from a stationary vessel. Shows how the CR30‑40 picks up multiple animals at varying range.
Recording location & conditions
All three recordings were made in Port Stephens, NSW — one of Australia's most active cetacean habitats. Humpback whales migrate through seasonally; resident bottlenose dolphin pods are present year-round.
No post-processing
No equalisation, noise reduction, or enhancement beyond level normalisation. These represent actual field performance — the clarity and frequency response you will get when you deploy the hydrophone from your own vessel.
