what is sound
Sound can be strong and weak, deep and normal, it depends on the intensity of what or who is doing it. Sound is not the other person’s speech, it can also be from the TV. In this link there is a video about sound.

what is sound?
Sound is a sound that you can hear or if it is really, really loud you can even maybe feel it.
Sound is a type of wave, and can propagate through gas, liquid, solid, and plasma. According to another definition, sound is a by-product of cycles of molecular compressions and dilutions, or longitudinal waves that propagate through a medium (the material in which the sound propagates, for example the air, through which the sound passes for example in a normal conversation between people), which can be compressed (any material except empty). The sound generator is also called the “wave source”. Sound waves can be described graphically, where one axis is the axis of time or space, and the other axis is the density of the medium.
My experiments
The Ear: The ear experiment was noisy and what happened was that we knocked on the table while his ear was resting on the table.
Vibrations: With the tremors we took an iron vessel and put it in a glass cup with water inside the cup and watched how the water splashed out of the cup and then we put baking paper on top of salt and there it blew everything away.
The ear consists of three parts – the outer ear, the middle ear and the inner ear. The sound waves each time vibrate a different substance in the passage until they are absorbed by the receptors in the inner ear.
And there is also the eardrum.
