Peer-reviewed evidence that targeted sound frequency compositions measurably improve cognitive performance, recovery, sleep, and autonomic regulation — across the five performance domains.
Learn MoreStress is the #1 limiter of human performance. It isn’t just a feeling, it’s a physiological state that impacts how you think, sleep, and perform. Chronic stress is driving poor sleep, mental fatigue, and decreased resilience—quietly compounding over time. In fact, up to 90% of all doctor visits are linked to stress-related conditions (WebMD).

Sound frequency refers to the number of oscillations of audible sound waves per second, measured in hertz (Hz). Specific sound frequencies have different effects on the body, and are used in Soaak's sound frequency compositions to target specific areas to generate outcomes using the body's innate mechanisms.
I listen to the sleep sounds right before bedtime and the calming sounds during the day if I need a boost to relieve stress or anxiety. My mind and body are enriched daily by the Soaak App.
The science behind this outcomeAcross 800 million hours of sleep data, third-party researchers found that Soaak's proprietary sound frequency compositions:
Soaak has been a game-changer for my team and me. In a world that is ever changing and driving anxiety for many, it is GREAT to know we have a partner and resource that our associates and their families can rely on.
The science behind this outcomeSoaak’s sound frequency compositions are created by using multiple frequencies in one audio track for specific outcomes. Soaak's sound frequency compositions can be delivered through a variety of methods, including the use of speakers, headphones, and bone-conducting headsets.
A global dataset demonstrating Soaak's measurable impact on the core HPO outcomes — stress regulation, cognitive function, mood, and sleep performance — across 190 countries.
