A sound wave is a type of pressure wave that travels through the air. As the wave travels into the ear canal (fancy name=external auditory meatus), it first will hit the ear drum (tympanic membrane). Since the sound wave is actually a pressure wave, it will push against the ear drum which will then rebound. This results in a vibration of the ear drum.
The ear drum is connected to three little bones (malleus, incus and stapes) - the smallest bones in your body. These bones (together called the ossicular chain) rock back and forth when the ear drum vibrates thereby transmitting the pressure wave down the ossicular chain to the cochlea.
The cochlea is a fluid filled sac and the ossicular chain is connected to it. As the ossicular chain vibrates, it pushes against the fluid in the cochlea. This causes the fluid to move around in a particular way so that special hairs within the cochlea are moved.
These hair cells are in turn attached to a nerve cell. As the hair cells are moved, they activate the nerve cells which send information down a chain of neurones going up your brain stem, to your thalamus (medial geniculate nucleus) and then to your brain's auditory cortex which is when you perceive sound.
the tympanum (ear drum) to vibrate
eardrum
Sound waves technically enter through the Auricle, the outside, visible part of the ear. From there, they hit the Tympanic Membrane (ear drum) and vibrate the ossicles (small bones in the ear), where the waves are transferred into the cochlea and organ of corti, where they're detected and changed to nerve impulses.
The two are different because Sound waves are longitudinal mechanical waves, but light waves are transverse electromagnetic waves, and sound requires a medium through which to travel, but light doesn't. Basically, Sound waves move sort of differently than Light waves.

Laser Sound Waves are used in modern painless surgeries.
The auricle or pinna of the outer ear acts like a horn to capture the sound waves which are then tunneled into the auditory canal and strike the tympanic membrane (eardrum).
Sound waves are detected by the fact that the waves can cause objects to vibrate. The vibrations from the sound waves must be converted into a signal and then amplified and processed. Your ear and a microphone are common detectors of sound.
The ear canal.

Electromagnetic waves only cause sound pollution because they are sound waves.
The combination of two or more sound waves can cause what is known as interference.
when you hear things, its really sound waves. the sound waves enter your ear, then it vibrates the ear drum.

Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.
