Sensory organ capable of detecting sound.
The organ of hearing, which is divided into three parts: the outer, middle, and inner ear
the sense organ for hearing and equilibrium
good hearing; "he had a keen ear"; "a good ear for pitch"
Where we hear all of our sounds. It works with a very complex mechanism(s). A short description of how the ear works is as follows: The sound travels in longitudinal waves, thus these waves hit the typanic membrane (eardrum) and cause pressure variances in the ear. these pressure variances travel through the hammer, then to the anvil and finally to the stirrup, which is attached to the oval window. These act as a interlocking mechanism, which allows sound to be heard. Since the oval window is 1/20th the area of the eardrum, sound is multiplied by a factor of 20. These lead to a end magnification of 40 x. The cochlea has small hairs inside of it vibrating at their natural frequencies when the sound enters this part of the ear. 23 000 of these small hairs send nerve impulses to the brain, where it is processed into a sound.
An ear tells you to keep your ears open. Chances are you'll hear something you wouldn't expect. It can also suggest that it would be in your best interests to take heed of some advice that has been given to you.
The human ear, as a sound receiver, has to operate under a wide range of conditions.
The sensory organ for hearing.
An incredible hearing mechanism consisting of outer, middle and inner ear segments that cause sound pressures to be picked up by the ear that are transmitted through auditory nerves where signals are interpreted by brain as sound.
The ear is the sense organ that detects sound. The vertebrate ear shows a common biology from fish to humans, with variations in structure according to order and species. It not only acts as a receiver for sound, but plays a major role in the sense of balance and body position.
