The outer ear picks up sound waves from the air around it and moves them along your ear canal to the middle ear, where the sound waves vibrate the eardrum, sending the sound along to the inner ear.
Ear picks, also called ear scoops, or ear spoons, or earpicks, are a type of curette used to clean the ear canal of earwax (cerumen).
In Asia, these are traditionally made from bamboo or precious metals such as silver or gold, but more commonly now, from stainless steel or plastic. European ear scoops produced up to the early 19th century were made from either bronze or precious metals such as silver.
