Sound Health

Sound Health, founded in 2019, is a company that has developed an innovative approach to treating nasal congestion and rhinitis-related symptoms. The company's primary product is Sonu, an investigational acoustic resonance therapy (ART) headband designed to alleviate nasal congestion. Sonu works by delivering vibrations at the resonant frequency of each patient's sinonasal cavities, which is determined by their unique anatomy. The device consists of a headband worn around the forehead, housing two bone conduction transducers. It connects via Bluetooth to a smartphone app that uses the phone's camera to capture anatomical landmarks. An algorithm then calculates the volumes of the maxillary sinus, ethmoid sinus, and nasal cavity to determine the appropriate resonant frequency for the individual, typically falling within the 100 to 1,000 Hz range.

In a randomized trial published in the International Forum of Allergy & Rhinology, Sonu demonstrated significant improvements in nasal congestion symptoms compared to a sham therapy. The study showed that after two weeks of treatment, patients using Sonu experienced a greater reduction in their Total Nasal Symptoms Score (TNSS) nasal congestion subscore and overall TNSS compared to those receiving sham therapy. The response rate, defined as improvement greater than the minimal clinically important difference, was also higher for Sonu users. Importantly, no intervention-related severe or non-severe adverse events were reported during the trial. The company positions Sonu as an alternative to traditional treatments like intranasal corticosteroid sprays, offering a non-pharmacological option for patients concerned about side effects associated with conventional medications.
