'Vibration' isn't captured by the outer ear. It is a sound that is captured through 'bone conduction'. Many hard of hearing or 'deaf' people pick up vibration through their skeletal structure. The Inner ear (the cochlear) is primarilarly bone, where the hair cells live which, by an electrical conversion process, tells the brain, that it has 'heard' a sound. In 'normal' or 'average hearing people', sound is captured by the outer ear in the 'concha',(the shell like part of the ear) and fed into the ear canal towards the eardrum and then into the inner ear. Blockages such as wax can inhibit the transmission of sound through the 'normal' hearing process but usually age contributes to hearing loss in the same way that joints, sight etc deteriorate through advanced ageing. This is due to a 'wearing away' of the hair cells of the inner ear.

What is the function of the external ear and how does it contribute to the overall process of hearing?

The external ear, including the ear canal and the pinna, helps to collect and funnel sound waves into the ear canal. This process helps to amplify and direct sound waves towards the eardrum, which then vibrates and transmits the sound to the inner ear. Overall, the external ear plays a crucial role in capturing and transmitting sound signals to the brain for processing and interpretation.


How does the external auditory canal transmit sound waves to the inner ear?

The external auditory canal collects sound waves and funnels them towards the eardrum. The eardrum vibrates in response to the sound waves, which then transmit the vibrations to the three small bones in the middle ear. These bones amplify the vibrations and send them to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for interpretation.


Supports the external ear?

The external ear is supported by the elastic cartilage of the auricle (pinna). This cartilage helps maintain the shape and structure of the external ear, allowing it to collect and direct sound waves into the ear canal towards the eardrum. The external ear also contains the earlobe, which is primarily composed of fat and connective tissue.


The external acoustic meatus is a foramen in which skull bone?

It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.


What structure in the ear converts sound waves into nerve impulses?

In general, the cochlea. More specifically, an impulse is carried into the brain along the auditory nerve when the tectorial membrane and the basilar membrane inside the cochlea are pressed together by the force of sound waves.

Part of the ear that catches sound waves?

External (outer) ear.


Which structure catches the wave and stops the vibration through the cochlea?

The structure that catches the wave and stops the vibration through the cochlea is the round window. It functions to release the pressure generated by the movement of fluid within the cochlea, allowing for proper transmission of sound waves through the inner ear.


What structure in the ear changes sound waves in the air into vibrations?

The structure in the ear that changes sound waves in the air into vibrations is called the eardrum.


What catches the sound waves?

Sound waves are caught, or absorbed, by surroundings such as walls, floors, and objects, which then vibrate and transmit the sound further. Materials like foam, carpet, curtains, and acoustic panels are commonly used to absorb sound waves and reduce echoes in a room.


True or False The structure that allows equalization of the pressure in the middle ear with that outside the body is the external auditory meatus?

False. The structure responsible for equalizing pressure in the middle ear with the outside is the Eustachian tube, not the external auditory meatus. The external auditory meatus is the passage that leads sound waves from the external ear to the middle ear.


How does resonance work in the context of sound waves?

Resonance in sound waves occurs when an object vibrates at its natural frequency in response to an external sound wave. This amplifies the sound and can create a louder, clearer sound.


How does the external ear work?

The external ear acts as a funnel to collect sound waves and direct them towards the middle ear. The shape and structure of the external ear help to amplify and localize sounds, while also providing protection for the delicate structures of the middle and inner ear. Sound waves enter the ear canal, causing the eardrum to vibrate and transmit these vibrations to the middle ear ossicles, which then amplify and transmit the sound further into the inner ear for processing.


How does the structure and function of the external ear of a human relate to the structure and function of the external ear of a rabbit?

Both the external ears of humans and rabbits serve to collect and amplify sound waves to the middle ear. Their structures include the pinna (ear flap) and ear canal. However, rabbits' ears are larger and more mobile, enabling them to better detect predators and prey through sound localization.


What is made up of two parts and gathers and funnels sound waves?

Sound waves travel from the air to the tympanic membrane by way of the?

external auditory meatus


What is the function of the external auditory?

The external auditory meatus is the ear canal that allows sound waves to pass from the external environment to the tympanic membrane (ear drum).


What is wave guide?

A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves. There are different types of waveguides for each type of wave.
