From Music to Health: Google launch ANC earbuds as Cardiac monitors

Delhi : With the use of a software update, Google researchers have created a new technique dubbed APG (Audioplethysmography) that can convert any current ANC earphones into heart monitors. Google launch this new technology in a research article titled "APG: Audioplethysmography for Cardiac Monitoring in Hearables."

Using the speakers of ANC earbuds and headphones, Google claims that APG is an acoustic sensing device that emits a low-intensity ultrasonic probing signal and then picks up the echoes with the onboard microphones. The business then analyzes and converts the ultrasound echoes into heart rate data using a mathematical model.

In an eight-month field research, Google evaluated APG with 153 people and discovered that heart rate readings (3.21% median error) and heart rate variability readings (2.70% median error) are reported with high accuracy by APG.

Even while music is playing on the earphones and the body is moving, like when jogging, the technology continues to track cardiac activity.

In an effort to enhance the technology's effectiveness, Google is currently concentrating on testing APG during more strenuous motion exercises like boxing, trekking, weightlifting, and HIIT (high-intensity interval training). The business thinks that APG might open up a ton of additional fascinating prospects for health research.
