As part of the external ear, the auricle or pinna acts like a horn to capture sound waves. They are then diverted or collected into the auditory canal. At the end of the canal is the tympanic membrane (eardrum) which changes the sound into vibrations to be transmitted further into the ear.

What is the part of the your ear we can see is?
The three sections are the outer ear, middle ear, and inner ear. There are links below to the images of the ear's anatomy.
What part of the ear receives sound waves first?
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).
what part of the ear collects sounds in the environment?
Sound waves are 'collected' by the ear drum. This is a film stretched across the ear canal. Much like it's namesake, it responds to sound waves by vibrating. These vibrations are read as electrical signals by your nerves, and it is transmitted to brain as impulses.
What external ear structure catches sound waves?
'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.
Which part of the ear traps sound?
The Pinna which is the external ear
What fleshy part of the ear helps you hear sound?
gathers sound waves.
Part of the ear that catches sound waves?
External (outer) ear.
Name the part of the outer ear that directs sound waves to the tympanic?
That part is called as ear lobe or the pinna of the ear.
Is the pinna part of an endocrine gland?
The pinna is the outer part of your ear that helps funnel sound into the middle and inner ear
Why is the outer ear soft and flat?
So sound waves can bounce off the ear into the inner part.
What does the helix do in the ear?
Your entire outer ear is designed to funnel sound into the inner ear, and the helix is just a particular part of it.
How does sound get from sources to your ear?
The fleshy part of the outer ear collects the sounds and pulls them in to the canal and closer to the ear drum where they bounce off and reflect the sound back to the part of the brain that tells you ears to hear.
What is the the function of the outer ear?
The outer ear collects and funnels sound waves to the eardrum, where vibrations are carried into the middle ear.
What is the function of the eardrum inner ear and outer ear?
to transmit sound entering the outer ear to the bones of the middle ear
What does the outer ear do to sound?
gather sound waves
What is the purpose of the outer ear?
The outer ear helps sound to travel to the inner ear. It is responsible for collecting sound waves and directing them to the middle ear via the auditory canal.
What is made up of two parts and gathers and funnels sound waves?
the eardrum is made up of 2 parts gathers and funnels sound waves
