We can hear sound as when when something makes a noise it vibrtates and we hear it because we have ears.
Sound goes through our ear cannal. The flesh part of our ear is called the pinna and it helps us locate the direction of the sound
the ear drum ossiclates with the sounds and allows it to travel to the ossicles which then travels to the liquid filled cochea which then is detected by the hair like cells and goes into the nerve cell is connected to it

Different wavelenghts, frequencies,
and amplitudes will cause different
sound waves to sound diffrent

Hertz
A hertz often symbolised as Hz, is the unit of measurement for frequency

what are waves?
-
Even though waves involve movement, they do not move matter. Alternatively motion of materials that a wave travels through will result in the matter returning to its original place.
A wave is a disturbance that carries energy from one point to another. This movement of the disturbance is referred to as propagation.

how the human eye works
when light enters your eyes light enters the eye through an opening called the pupil. The iris (the colored part of the eye) controls how much light the pupil lets in. Next, light passes through the lens (a clear inner part of the eye). The lens works together with the cornea to focus light correctly on the retina

when a wave hits a blocking blocking point or a barrier they may or may not be able to pass through it depending on the type of wave an what it hits

Frequency is a measure of how many full oscillations occur in one second or how long it takes for 1 full oscillation to occur.
The wavelength of a wave is a measure of the distance from the peak of one wave to the peak of the next
