Chi si trova a dormire con un compagno di letto che russa potrebbe presto dire addio alle notti insonni. Alla Northern Illinois University è infatti stato sviluppato un prototipo di cuscino in grado di cancellare i fastidiosi rumori notturni.
Il cuscino ha infatti integrato un dispositivo che registra i suoni del russamento e produce onde sonore di uguale ampiezza per bloccarli. L'uso dell'intelligenza artificiale permette anche di adattarsi ai cambiamenti nel modo di russare che possono intervenire durante la notte.
Secondo i test il sistema è in grado di ridurre il rumore di circa 30 decibel, diminuendo di quasi due volte il rumore percepito.
