Pink Noise + Pebble Beach Waves

10 Hours | Hear one of our most popular sounds, Pink Noise, paired with our special 2024 Earth Day sound: Pebble Beach Waves. Pink Noise is darker and emphasizes lower frequencies than white or brown noise. This creates a strong wall of sound to drown out background noise. Pebble Beach Waves is the sound of gentle waves move thousands of pebbles on a rocky shore, making them smoother with each splash. The sun is setting, the stars are coming out, and a night of peaceful sleep awaits.
