HeadSense’s earbuds work by emitting low-frequency sounds and monitoring changes in the sound waves as they pass through the brain. Increased pressure causes blood flow in the brain to decrease. According to HeadSense, the corresponding narrowing of the blood vessels causes the sounds to raise in pitch. The data is fed wirelessly to a tablet which performs the calculations to convert the measurements into a pressure reading.
