Description of how sound propagates in the air and through solids, how sound waves spread and what they vibrate.
Sound transmission in the ear
The sound moves through the air to reach the listener's ears.
Furthermore, it is also transmitted by means of water and solid materials, including steel and glass.
For this reason, despite being closed in the house, external noises are heard.
The propagation of sound occurs through sound waves produced by the vibration of the air triggered by simple speaking, playing an instrument and any other type of noise.
The sound waves move away from the source that generated them and reach the eardrum of our ears, which make them vibrate, enabling us to hear voices and sounds.
The frequency represents the number of sound waves per second, the higher this number the higher the volume of sound heard.
