Any noise-cancelling headset may be converted into a heart rate monitor by Google

Smartwatches are not the only gadgets that can detect heart rate. Google has demonstrated to the world that their noise-cancelling headphones can measure heart rate. No, no external or additional ingredient is required to make this a real-world possibility.

Google has explained how they got the ability of headphones to track heart rate in a blog post. Google has modified its headphones to function as an audioplethysmograph.

Google creates noise-cancelling headphones that can track pulse rate.

The device, known as audioplethysmography (APG), measures heart rate and heart rate variability (HRV) using feedback microphones embedded into the headphones and a low-intensity ultrasonic signal.

The ultrasonic signal is sent via the earphone speakers and reflected into the ear canal, where vibrations from the heartbeat and ear canal skin alter the reflected signals. Google has demonstrated that this strategy works even while music is playing and the headphones are not adequately sealed.

APG technology is a less invasive and less expensive alternative to standard sensors such as photoplethysmographs (PPG) and electrocardiograms (ECG). Furthermore, no new hardware is required, which means that any noise-cancelling headset may be transformed into a heart rate monitor with a simple software update.

Google performed two trials with 153 persons to assess the APG’s accuracy. The results reveal that the APG measures heart rate accurately and consistently (3.21% median error across all activity situations) and heart rate variability (2.70% median error across interbeat intervals).

APG is also unaffected by skin tone, ear canal size, or poor sealing conditions. Google has created cutting-edge technology that turns any noise-cancelling headset into a heart rate monitor.QuillBot’s paraphraser alters your phrases, allowing you to revise and republish your material more rapidly and efficiently!

It does not require any additional hardware, which means that any noise-cancelling headset may be transformed into a heart rate monitor with a simple software update. Of course, Google has stated that it would not be available in the near future for its headphones.
