The Power of Sound Frequencies
Welcome to Koolá – An Australian designed comfort doll, lovingly created by a mother for her daughter.
Koolá was born from a simple intention: to help children feel calm, safe, and supported through sound.
If you’re here, you likely appreciate the gentle power of sound therapy and the way certain frequencies can support relaxation, rest, and emotional regulation.
The Koolá Doll is a unique comfort toy. It features a curated collection of soothing soundtracks tuned to 528 Hz and layered with carefully selected isochronic tones. Every track is designed to support a relaxed state – whether for winding down, sleep, or moments when little nervous systems need extra reassurance.
Across the sound library, calming sound waves are used that align with:
1) Naturally occurring harmonic frequencies, and
2) Brainwave states commonly associated with rest, calm, and sleep.
These sounds are not meant to stimulate, but to gently entrain the body toward stillness, creating a peaceful sensory environment your child can return to again and again.
(See the diagram below to explore which soundtracks align with each frequency.)
Koolá is a soft companion for quiet moments – designed to support rest, comfort, and emotional ease in a way that feels natural, nurturing for the early years of childhood.
