Ears — hyper-acute hearing
12-mic beamforming array, 20 Hz–96 kHz, on-device acoustic event classifier.
Six MEMS microphones per side (twelve total) form a beamforming array with a measured noise floor of 22 dBA and a usable frequency range of 20 Hz – 96 kHz — well into the ultrasonic band used by rodent infestation, leaking gas valves and ultrasonic pet deterrents.
The array steers up to four simultaneous beams, so the companion can isolate a child's voice across a noisy room, follow the speaker while a kettle boils, and still monitor the front door. Source localisation is accurate to ±2°.
An on-device acoustic event classifier recognises > 500 sound categories — breaking glass, a smoke alarm, a cough, a fall, a baby's cry — with sub-100 ms latency, locally, before any audio leaves the device.
