Noise can also be describe as sound ,noise is caused by something that vibrates, that moves back and forth. Our ears receive the consequences of this vibratory motion from a distance, nice or tiny, via sound waves. These waves are sequence series of regions of compressed gas and partial vacuums, or areas of high and low atmospheric pressure. Sound also can travel through liquids and solids. we have a tendency to hear sound as a result of our eardrums which are stirred back and forth by the changes in atmospheric pressure. The tympanum, or tympanum , might understand a sound that moves it just one billionth of a centimeter—the threshold of hearing. If the intensity of instantaneous sound pressure becomes too nice, we have a tendency to expertise pain, and therefore the tympanum or the fragile structures within the ear may be broken.terribly blast will harm the tympanum, most physiological harm from noise happens within the snail-shaped, liquid-filled tube-shaped structure , or labyrinth. Sound transmitted to the tube-shaped structure produces waves within the liquid, that successively move delicate and minute structures referred to as hair cells or cilia in this a part of the tube-shaped structure called the organ of Corti. The motion of the cilia is remodeled into electrical impulses that conduct the feeling of sound to the brain.
WHAT HAPPENS TO YOUR EARS AT HIGH NOISE ?
The sounds enter the ear. The ear lobe acts a funnel to catch the sound waves and guide them down the meatus.
The sound waves vibrate the membrane that successively vibrates the 3 little bones i discussed at the beginning of this text.
The vibrations are then send to the sensory receptor, that is formed sort of a snail and is stuffed with fluid. This fluid then conjointly vibrates and passes it onto one thing referred to as the tissue layer. This contains little hairs that “ride” the wave of sound passing through.
These hair cells then produce a chemical change inflicting AN electrical signal, that is then saw the nerves vestibulocochlearis to the brain.
The brain picks up the sound from the nerves vestibulocochlearis and converts it into one thing that we are able to perceive or understand.
THINGS TO DO TO PREVENT NOISE TO AFFECT OUR EAR DRUM
Wear protective devices when involved in a loud activity
Move away from the noise if you can’t protect yourself from it
