Sleep well, ask the phone to know

Recently, researchers have been working on a way to easily track sleep apnea, which is achieved by headphones and smartphones with a microphone in a bedside cabinet, which tracks your insomnia. The study was led by Stevens Institute of Technology and Florida State University. In a six-month study, the researchers recorded the breathing sound of six cheap beats by dre subjects through earbuds, including wired lines. Even if the earplugs were placed on the bedside bedside table, they could also use the microphones of the headphones to monitor Try to breathe. The accuracy of this method is similar to that of a chest-belt respiration monitor, and it can be done on the collar of the subject.

Ying Ying Chen, an associate professor at the Stevens Institute of Technology, said the researchers were preparing to develop a sleep apnea surveillance next year. This APP will make people more convenient and spend less money to achieve accurate monitoring of sleep quality, without smart bracelet and other devices.

Do not need to wear equipment on sleep?

Even if the market size of wearable equipment continues to grow, enthusiasts are constantly increasing, and in fact wearing wear is uncomfortable and the data is not accurate.

Chen also hopes that this project will help patients with sleep apnea. In fact, such patients need to wear a variety of sensors, and sleep when the need for professional medical staff custody. Chen believes that this traditional way is not conducive to treatment.

Researchers tested the sensitivity of the microphone on the earbuds to record the respiratory rate, improved the function of the earplugs, such as increasing the mono and stereo effects, while separating the ambient noise such as snoring and coughing, The microphone can accurately capture the sound of sleep breathing. When the microphone on the headset is placed in a pillow or in close proximity, its measurement is the most accurate. However, the study also shows that this earplug in the bedside cabinet can also play a very good effect.

Of course, this headset project is good, but the key question is, in a room, how does it identify more than one person's breathing frequency? Or do some people like to sleep with pets? The above problems may be resolved, because now a lot of smart phones in order to noise, there will be several sound module. If the phone can develop into no headset, directly through the phone in the sound module to record the sound of breathing, that is excellent.
