Besides not being able to hear a person who can’t usually hear can’t talk to other people. They have to use sign language to speak to others, and even that is difficult because a lot of people aren’t taught it. Another sense is that they wouldn’t be able to protect themselves from immediate danger. Such as knowing something as simple if a car was going to hit them. So a lot of the time these types of people need an aid whether that is a service dog or some companion <span>that helps them with their daily activities.</span>
Sound is a form of Energy that produces a sensation of hearing in our ears.
Sound is produced as a result of vibration produced in a body.
Sound energy is transmitted from one place o other place by wave motion.
When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
During vibration, they collide with the surrounding particle and transfer some energy to them.
They then start vibrating faster and transferring energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
Thus, particles are an important factor in propagation of sound.
Sound cannot travel in vacuum.
It requires a medium to travel from one point to another.
A sound can travel in all medium, solids, liquids and gases as all of these have particles.
The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest in solids.
