Acoustic resonance happens when sound waves cause an object or system to vibrate at its natural frequency. This natural frequency of vibration denotes the maximal energy transfer in and out of the object.

Every object or space has its own natural frequency, which is the rate at which it vibrates. When sound waves with the same frequency as an object’s natural frequency hit the object, the vibrations grow stronger, creating resonance. 

When you blow across the top of a bottle, the air inside begins to vibrate, producing sound through a phenomenon known as resonance. This occurs only at the bottle’s specific resonant frequency—a natural pitch determined by the bottle’s shape, size, and the amount of air it contains. At this frequency, the air column vibrates most strongly. At other frequencies, as seen in the video, there’s little to no air movement.

Our sinuses function much like these bottles. They’re air-filled cavities that, like musical instruments, can resonate and modulate sound. Sonu’s bone conduction system, placed on the forehead, acts like a miniature tuning fork, stimulating the sinuses to vibrate at their unique resonant frequencies. This targeted vibration moves the air within the sinuses, delivering optimal vibrational energy to the nasal cavity—helping reduce inflammation and clear mucus.

The SONU app uses a face scan to determine each person’s unique resonant frequencies, allowing it to personalize acoustic resonance therapy for truly individualized relief.

SONU is clinically proven to be as effective as steroid sprays with ZERO side effects.

The key to how the SONU Band works lies in the science of acoustic resonance. When sound waves match the natural frequency of an object, like the sinus cavities, they cause stronger vibrations. The SONU Band sends these resonant sound waves through bone conduction from your forehead to your sinus cavities. These vibrations help loosen mucus and reduce swelling, making it easier to breathe. This method uses the body’s natural response to sound vibrations to effectively clear congestion.
