Why is low frequency so important?

In the vast natural world, infrasound acts like a 'radio wave' that can travel hundreds of kilometers through air, water, and even the earth's crust. Unlike high-frequency sounds, they are not easily blocked by forests or obstacles. Many top predators and migratory animals use specialized cochlear structures or vibration-sensing pads on their feet to capture these natural whispers.

• Key Fact: Blue whale communications occur at such low frequencies that a few vocalizations can span an entire ocean basin.
• Evolutionary Strategy: For elephants, low frequency is not just sound, but a 'vibrational language' transmitted through the ground.
