Sounds for Thunderstorms and Fireworks when the sky will not cooperate.
Fireworks are somebody else's celebration happening directly at your child. Thunder is worse, because nobody scheduled it and nobody can say when it stops.

What frequency-tuned audio does for sudden loud noises
Sudden, unpredictable, high-volume noise triggers a startle response the body cannot talk itself out of, and each new bang restarts the alarm. Steady sound in headphones masks the peaks and gives the ears something continuous, while the breath pacing helps the body come down between the bangs instead of stacking them.
What makes this moment hard
- The unpredictability is the trigger, so there is nothing to count down to.
- It often happens at night, when reserves are already low.
- Everyone else is enjoying it, which adds isolation to the fear.
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 sudden loud noises
A starting point, not a prescription. Take the steps that fit your family and leave the rest.
- 1 Set up before it starts, when a storm or a holiday is forecast.
- 2 Use over-ear headphones with the audio, not earbuds.
- 3 Choose an interior room with fewer windows, if one is available.
- 4 Stay with the session through the loudest stretch rather than checking outside.
- 5 Let your child decide when to take the headphones off.
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.

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.
