The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three parts—the outer ear, middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localisation.
The ear develops from the first pharyngeal pouch and six small swellings that develop in the early embryo called otic placodes, which are derived from ectoderm.
The ear may be affected by disease, including infection and traumatic damage. Diseases of the ear may lead to hearing loss, tinnitus and balance disorders such as vertigo, although many of these conditions may also be affected by damage to the brain or neural pathways leading from the ear.
The ear has been adorned by earrings and other jewellery in numerous cultures for thousands of years, and has been subjected to surgical and cosmetic alterations.

    What ear muffs give a good cheek weld?

    I have some Impact sport muffs. While great for a pistol they do not fit well for me with an optic and trying to get a good cheek weld and sight picture. I prefer to use muffs and plugs when shooting the .308

    Electronic Ear Protection Question

    I’ve been going back and forth between the Walker Razor XV (neck band with retractable ear buds) and the Silencer ear buds. Both seem to have advantages over each other. I’d prefer the cordless type but really worry about losing the bud out of an ear. If you’ve tried them please chime in!

    Ear Protection When Bench Shooting

    I've always had problems with regular "ear muff" type attenuators being too large and being almost not usable when firing rifles. The main issue is that the ear muffs make contact to the rifle stock before my cheek reaches the cheek rest. Are there any good ear protection products out there...

    Why doubling-up hearing pro only gains you ~5dB

    I'd read several places that doubling-up on hearing pro only gains you about 5dB additional attenuation above the higher-rated of the two, regardless of their ratings, and wondered why. (If you wear 25dB ear plugs, and then put on 30dB ear muffs, the total attenuation isn't 55db, it's actually...
