Audio for Sensory Overload before it turns into a shutdown.
The lights hum, the room is too bright, three people are talking, and somewhere in the middle of it your child stops responding. Overload does not announce itself politely.

What frequency-tuned audio does for sensory overload
Sensory overload happens when incoming input outpaces the ability to process it, and the usual fix, removing input, is not always available in a store or a classroom. Predictable, low, slow sound over headphones replaces chaotic input with something the body can anticipate, and the breath pacing gives the nervous system a direction to move in.
What makes this moment hard
- Leaving is not always an option, and the overload does not wait for a better time.
- Noise-cancelling alone removes input but gives the body nothing to settle into.
- The recovery afterward often costs the rest of the day.
Resyna does not ask anyone to try. It follows the listener's heart rhythm and uses gentle, adaptive tones to guide breathing toward a slower, steadier pace, with no counting, no instructions, and no screen to look at.
How to use Resyna for sensory overload
A starting point, not a prescription. Take the steps that fit your family and leave the rest.
- 1 Move to the least stimulating spot available, even a car or a hallway.
- 2 Put over-ear headphones on and start Resyna at a low volume.
- 3 Dim the visual input too: eyes closed, hood up, or facing a blank wall.
- 4 Stay put for the full session rather than rushing back in.
- 5 Re-enter slowly, and expect the next hour to need a lighter demand.
Start with two to five minutes at a comfortable volume, and stop any time it does not feel right.
Your body already knows this rhythm. Resyna just holds the door open.
It listens back
Press play and Resyna follows the listener's heart rhythm in real time. As the body settles, the sound settles with it.
It guides the breath
Soft, layered tones pace breathing toward a slower rhythm. Around six breaths a minute is where the body's stress and recovery systems settle back into balance.
It leaves room to breathe
Built with space in it rather than sound filling every second, and it needs no screen. Eyes closed, headphones in, and the calm comes to you.

We would rather earn your trust than your click.
Resyna is not a medical device.
It is a wellness tool designed to support calm and focus. It does not diagnose, treat, cure, or prevent any condition, and it is not a substitute for care from a qualified professional.
We skip the "brainwave" hype.
The research does not reliably support binaural beats retuning your brain, or special "healing frequencies" like 528 Hz. Resyna is built on paced breathing, which does have a strong evidence base, not on claims we cannot stand behind.
Sound is not right for every child.
Many autistic people experience sound sensitivity. That is exactly why Resyna is opt-in, volume-capped, and caregiver-controlled. If sound is not the right tool for your child, that is a completely valid answer.

Sound settles the body. A visual schedule answers the questions.
Most hard moments need both. These free step-by-step guides cover the same situation from the planning side.
A gentle note on safe use. Resyna and VizyPlan's Calming Frequency are wellness tools designed to support relaxation. They are not a medical device and are not medical advice. They do not diagnose, treat, cure, or prevent any condition, and they are not a substitute for care from a qualified professional. Start with just 2 to 5 minutes at a comfortable volume and build up gradually. If you feel any discomfort, dizziness, or unease, stop right away. If you are pregnant, or you or your child has epilepsy, a seizure disorder, or a heart condition, please check with your doctor before use. Do not operate heavy machinery after listening. Use of the heart-guided calm score requires a paired Apple Watch with heart-rate and health sharing enabled. The calm score is a relaxation-feedback indicator only. It is not a diagnosis, a fitness metric, or a measure of your health. Resyna does not monitor for, detect, or alert you to arrhythmias, heart conditions, or any other medical issue, and it should never be relied on for that purpose. If you have any health concern, contact a qualified medical professional.
