Sonar sleep tracking uses inaudible sound waves to monitor sleep
Sonar sleep tracking is a safe and accurate way to monitor sleep. It uses inaudible sound waves to track sleep patterns and provide insights for better rest. The SleepScore app, for example, uses sonar technology to send out inaudible sound waves through your phone's speakers and then receives them back through the microphone. This allows the app to measure bodily movement and sleep duration, including the time it takes to fall asleep, light sleep, deep sleep, REM sleep, and wake time. It is even sensitive enough to measure respiration and recognize REM (rapid-eye movement) sleep.
The sound waves used by these apps are well within the range considered safe. They are above the level of normal adult human hearing and are transferred through the air rather than applied directly to the body, emitting minimal energy. In fact, we encounter sound waves in our everyday lives simply by communicating with others and experiencing the world around us.
The SleepScore app also ensures data privacy by processing only the sonar signals in its range and ignoring other sound frequencies. All audio data is destroyed at the end of each sleep session, so no sound is ever stored or saved.
While sonar sleep tracking is generally safe, it is worth noting that children and young adults may be able to hear the sonar signals in some cases due to their ability to hear different sound frequencies than adults. Additionally, while the SleepScore app can provide insights into sleep patterns, it cannot give details about your bedroom environment, such as light and temperature levels, which can also impact sleep quality. For that, SleepScore offers a separate device called SleepScore Max, which uses safe, ultra-low-power radio waves to measure your breathing and movements while also providing environmental sensors to optimize your bedroom for better sleep.

SleepScore is an example of a sleep-tracking app that uses sonar
SleepScore is a sleep-tracking app that uses sonar technology to track your sleep safely and accurately. The app uses inaudible sound waves to measure bodily movement and sleep patterns. It measures sleep duration, the time it takes to fall asleep, light sleep, deep sleep, REM sleep, and wake time. It is sensitive enough to measure respiration and recognise REM (rapid-eye movement) sleep. The app also offers a smart alarm that wakes you up during lighter moments of sleep.
SleepScore is unique in that it does not require any wrist or bed sensors or extra bedside devices. Instead, it uses your phone's speakers and microphone to send and receive sound waves, assessing your sleep quality based on breathing and movement. The sound frequencies used by the app are above the level of normal adult hearing and are well within the safe range. The app is designed to raise awareness of sleep disorders and provide insights to guide better sleep.
SleepScore offers a free version that tracks seven days of sleep, while a subscription for $4 a month provides a complete sleep history and allows you to format records to send to your doctor. The app is available for iOS and Android devices, although some features may vary depending on the device compatibility.
The effectiveness of SleepScore's sonar technology depends on proper positioning. The phone should be placed on a bedside table, plugged in, or laid on a charger, with the speakers aimed at the bed. The app recommends a slight elevation for optimal results.
SleepScore has been found to be more precise than other sleep-tracking apps in recording sleep duration and the frequency of wake-ups. It provides specific times for middle-of-the-night awakenings, which can be corroborated with a sleep diary. The premium version of SleepScore, priced at $50 per year or $6 per month, allows users to set goals and provides advice on achieving them.

Sonar sleep tracking is more accurate than accelerometer-based tracking
Sonar sleep tracking is considered a safer alternative to accelerometer-based tracking. Sonar sleep tracking uses sound waves to track movement during sleep. It relies on the principle that when objects (including humans) move, they create disturbances in sound waves around them. By analyzing how these sound waves bounce back after hitting surfaces near the sleeper, sonar sleep tracking can determine if there was any movement during sleep. This is considered safe as the sound frequencies used are above the level of normal adult human hearing and are well within the safe range.
Accelerometer-based sleep tracking, on the other hand, has its limitations. It detects movement and vibrations by measuring changes in velocity along different axes (X, Y, Z). While it may be more precise in measuring body motion directly, it might not capture all types of movements such as gentle rolling or tossing and turning under light covers. Additionally, accelerometer-based tracking relies solely on motion detection, which can lead to discrepancies when the user is lying still but is fully alert.
Sonar sleep tracking offers a more accurate understanding of sleep patterns by leveraging ultrasonic technology. It can precisely monitor sub-millimeter movements, which is a significant improvement over accelerometer-based tracking. This advanced technology is typically found in medical settings or bat navigation systems, showcasing its reliability and accuracy.
Furthermore, sonar sleep tracking is less susceptible to external factors such as background noise or bedding type. As it uses inaudible sound waves, sonar sleep tracking can accurately measure sleep duration, the time it takes to fall asleep, light sleep, deep sleep, REM sleep, and wake time, even in less-than-ideal environments. This level of detail provides a comprehensive understanding of sleep patterns, enabling users to make informed decisions to improve their sleep quality.
In conclusion, sonar sleep tracking offers a more accurate and reliable solution compared to accelerometer-based tracking. By utilizing ultrasonic technology and analyzing audio reflections, sonar sleep tracking provides a more nuanced understanding of sleep patterns, capturing even the slightest disruptions caused by breathing or muscle twitches. With its ability to precisely monitor movements, sonar sleep tracking empowers individuals to optimize their rest and make informed decisions for improved sleep hygiene.
