Hearing is one of the vital senses that human needs. While everyone realise that as we get older, the ability of hearing declines simultaneously. But have you ever wondered whether your ears are actually ageing at the 'standard pace', similar to people same age as yours? A little test from YouTube channel AsapScience will determine the age of your ears. It plays a series of pitches at various frequencies, where only people with certain range of age could listen to them. According to AsapScience, our hearing ability depends on tiny hair cells living inside our ears. Unlike other cells such as skin, liver, and the likes, the hair cells do not regenerate once they are damaged due to sound waves. Hence, our ability to hear decreases as we grow older.
