Human Ear
The ear is a human organ that allows us to hear sounds in our environment. The primary function of the ear is to keep us balanced and to distinguish different noises. It aids in the conversion of pressure fluctuations into electronic impulses that flow through the auditory nerve to the brain.
Human Ear is mainly divided into three parts as:
- Outer Ear
- Middle Ear
- Inner Ear
Outer Ear
Sound waves pass over the outer ear whenever they enter our ear. The ear translates audible frequencies into electrical signals, which are then transmitted to the brain. Pinna and earlobe are the large parts of the outer ear with a shell-like structure. The compressions that reach the outer ear, i.e. the pinna, are directed to the canal and eventually reach the eardrum or membrane. The inner ear and outer ear are separated by a flexible membrane. These compressions are magnified by the three bones inside the ear multiple times.
Middle Ear
Bones are found in the center of the body and are connected to one another. The three bones that convey sound are the hammer, anvil, and stirrup. The hammer is attached to the middle of the eardrum. The sound of the hammer vibrating is transmitted to the other two bones, the anvil and stirrup. The sound waves are amplified by these bones, which are located in the middle ear. So, what does the outer ear do? It draws in sound waves, which are then amplified by the inner ear.
Inner Ear
The Cochlea, or inner ear, is a snail-like structure. Because there is some fluid inside the cochlea, when the number of variations is conveyed in the middle ear, the cochlea sends the sound to the brain. The auditory nerve receives these electrical impulses.
Human Ear
It has been discovered that sound is a type of energy. Vibrations cause it to happen. Longitudinal waves are sound waves. Because they are elastic waves, they must be transmitted through a material medium. They can move through solids, liquids, and gases. In solids, their velocity is greatest, whereas, in gases, it is lowest.
In our daily lives, we hear a variety of sounds, including pleasant ones known as musical sounds, noise, loud sound, high-pitched sound, and other unpleasant sounds are examples. The majority of mammals on Earth have an external ear. Our auditory system includes the ear. The pinna is the part of the ear that is visible from the outside. Humans, like other mammals, have ears. The temporal bones of the skull house the ears on both sides of the brain. Before discussing the human ear and its range of hearing first we’ll discuss the production of sound and sound waves.
