Cambridge Sound Management Inc, creator of smart home sleep system Nightingale, announced the results of a clinical sleep study performed by Harvard Medical School and Brigham and Women’s Hospital, which show Nightingale significantly reduces sleep onset latency. Nightingale helped participants fall asleep 38% faster than when they tried to fall asleep without Nightingale. The outcome of sleeping with Nightingale was comparable to taking an above average dose of prescription sleep medication.

Nightingale is designed to help mask common disruptive indoor and outdoor noises, resulting in a better night’s sleep for the user. The system uses proprietary sound curves to blanket a bedroom in soothing ambient sounds, called sound blankets, optimized for each user’s room acoustics as determined through the Nightingale Sound app. Nightingale can account for health conditions like tinnitus or noises like snoring in an adjacent room. The system is controlled via the iOS/Android app, Bluetooth, or

Andrew Wellman, MD, PhD, Director of the Sleep Disordered Breathing Laboratory at Brigham and Women’s Hospital, says in a release: “This clinical trial studied the effects of ambient noise in a model of transient insomnia in a group of healthy subjects. The results suggest that sound blankets may be an effective way to minimize sleep onset insomnia in patients.”

Christopher Calisi, CEO of Cambridge Sound Management, says: “These results are a positive indication of what we already suspected—that Nightingale’s proprietary sound curves can help lull people to sleep faster than sleeping without this sound masking technology. Nightingale is unlike any other sleep product on the market, and we’re pleased the benefits are now supported by a clinical study.”

The results of the full study will be presented by the Harvard Medical School and Brigham and Women’s Hospital research team at the 2017 SLEEP Annual Meeting on June 4, 2017 in Boston. The study abstract is available now at
