At the*Ben-Gurion University in Israel researchers have developed a smartphone-based system for evaluating a patient’s*obstructive sleep apnea, as well as sleep-wake activity, an analysis of how sleepy one feels. The hope is that this tech**logy, which is easy and cheap to use, may one day serve as an option over traditional*polysom**graphy in some studies.

The software uses a smartphone’s microphone to listen to the sounds generated by a sleeping person. These are processed and categorized to identify unique events, such as s**ring, coughing, or wheezing.

In order to evaluate how accurate their software is, especially since this is certainly **t the first attempt at assessing sleep from sounds alone, the researchers conducted a study involving 350 subjects. They found that compared to traditional *traditional*polysom**graphy, their smartphone app was able to accurately identify sleeping events and evaluate obstructive sleep apnea and sleep/wake activity.
