Low-Frequency Ocean Hum
Deep Subsonic Rumble of Distant Ocean Swells for All-Night Sleep

Fall asleep to the deepest voice of the ocean with this unique soundscape that isolates and amplifies the low-frequency hum produced by large ocean swells moving across vast distances of open water. This is not the sound of waves breaking on a beach but rather the profound subsonic rumble that exists beneath the surface when massive bodies of water shift and breathe with the tides and weather patterns far offshore.
Recorded using specialized low-frequency hydrophones and enhanced to bring these normally imperceptible sounds into the audible range this audio reveals a side of the ocean most people never hear. The result is a continuous deep hum with slow organic fluctuations that create a uniquely powerful sleep-inducing effect.
The low frequencies resonate in the chest and body creating a physical sensation of being rocked by something immeasurably large and gentle. No high-frequency splash or surface noise intrudes on the pure deep-ocean foundation. Eight hours of uninterrupted subsonic ocean atmosphere provide a completely unique alternative to standard ocean wave recordings for overnight sleep.
