Bzzz! The Age Prediction Machine tests your date’s true age using high-pitched mosquito-like noises.
Fear not, folks in Japan have created a device to help answer that question.
The pocket-sized device, aptly called the “Age Prediction Machine,” emits high-frequency buzzing noises that are meant to help users determine someone’s age based on how well they can hear it.
The noise levels are broken down by age range: teens, 20s, 30s and 40-plus. People 25 and under will respond to the quieter settings, while those over 40 will only be able to hear the loudest.
