Whale Song: A Magical Experience on Oahu’s Waters
If you’re looking for an unforgettable whale-watching tour on Oahu, you’re in for more than just a visual treat! On our tours, you don’t just see humpback whales—you get to hear their mesmerizing songs with the help of a hydrophone.
What is a Hydrophone?
A hydrophone is an underwater microphone that captures sounds in the ocean. It’s designed to pick up even the faintest noises, including the enchanting songs of humpback whales.
Can Humans Hear Whale Songs Underwater?
Whales produce a wide range of frequencies, from 30 Hz to 8,000 Hz. However, humans can only hear part of their songs. We can’t detect the lowest frequencies, which start around 30 Hz. Humans begin hearing low sounds at around 100 Hz, so we only catch the mid-to-high notes. Despite this, the melodies you’ll hear through our hydrophone are magical and unlike anything else in nature!
Whale Songs and Sound Variations
Humpback whales make many different sounds. You may hear moans, cries, and howls. These songs are just one part of their vocal repertoire. Whales also use sounds like grunts, groans, snorts, and barks for communication and hunting. While both male and female humpback whales vocalize, it’s the males who perform the long, continuous songs we recognize as whale songs.
Humpbacks can sing for over 24 hours by forcing air through their nasal passages, despite not having vocal cords. Their songs vary depending on their population. Humpbacks in the North Atlantic sing a different song from those in the North Pacific—like regional dialects. Songs last 10-20 minutes, repeating constantly but slowly evolving over time. The theme changes in unison across the group, which remains a mystery to scientists.
While these songs usually can’t be heard by the human ear underwater, you’ll have the rare opportunity to listen through our hydrophone. It’s a truly unique experience that will immerse you in the magical world of humpback whales.
Why Do Whales Sing?
Humpback whale songs are believed to serve multiple purposes. The strongest theory links singing to mating. Males sing to attract mates, especially during the breeding season. The songs can also travel long distances, allowing whales to communicate with others across vast expanses of ocean.
Some scientists suggest that the songs might also serve a social function. Male whales may use them to challenge other males and defend their territory.
