About

WhisperSom is an Annapolis, Maryland medical device and informatics company, incorporated in Delaware in 2014 as a public benefit corporation, developing a treatment for obstructive sleep apnea. Its patented acoustic neuromodulation technology is delivered by a non-invasive wearable that resembles a precision health tracker worn around the chest, paired with earbuds designed for sleeping, and requires nothing on the face, in the mouth or nose, no surgical implant, and no electrical stimulation. The device is not yet commercially available; the company has submitted initial clinical data to the FDA and is pursuing a regulatory pathway, including possible breakthrough device designation. WhisperSom's stated goal is to at least double the roughly 5% sleep apnea treatment rate within five years of FDA authorization of its first device.

Acoustic neuromodulation delivered through a chest-worn tracker and sleep earbuds, avoiding the CPAP mask, oral appliance, and surgical implant formats that drive the low adherence rates in existing sleep apnea therapy.
