Sound waves enter the ear through the external auditory canal, which is a tiny tunnel that leads to the tympanic membrane (also known as the eardrum). The incoming sound waves cause the eardrum to vibrate, which in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
How are sound waves transmitted through the air?
The transmission of sound through the medium of air.Sound waves from the surrounding environment are guided through the tympanic membrane to the inner ear by the outer ear.The auricle, which is the part of the outer ear that is visible, is responsible for gathering sound waves and, in conjunction with the concha, which is the cavity at the entrance to the external auditory canal, assists in channeling sound into the canal.
How does sound enter the brain?
Journey of Sound to the Brain is an animated video that was produced by the National Institute on Deafness and Other Communication Disorders (NIDCD), the same organization that developed Noisy Planet. The video follows sound waves as they travel through the ear canal and are converted into electrical signals that our brains can interpret and understand.
