Auricle or pinna3
Tympanic17
Outer ear19
Called the auricle1
  • The external ear consists of the prominent pinna (also called the auricle) and the external ear canal (also called the auditory canal or meatus). (petplace.com)
Known as the pinna2
  • The outer part of the ear, whether they are prick ears or floppy ears are known as the Pinna or just flaps. (safehounds.com)
  • The outer part of a cat's ear, known as the pinna, can rotate up to 180 degrees, acting like a radar dish picking up signals from all around. (meowa.com)
Canal30
  • The auricle collects sound and, like a funnel, amplifies the sound and directs it to the auditory canal. (wikipedia.org)
  • For low frequencies, it behaves similarly to a reflector dish, directing sounds toward the ear canal. (wikipedia.org)
  • While some of the sounds that enter the ear travel directly to the canal, others reflect off the contours of the pinna first: these enter the ear canal after a very slight delay. (wikipedia.org)

  • Together the pinna and ear canal are referred to as the o uter ear . (myhearingcentre.com.au)
  • Sound waves are funneled by the pinna into the external auditory canal, which then causes the eardrum to vibrate. (entsinushearingcarecenter.com)
  • That works because the acoustical properties of the air and flesh are different, so sound gets channeled into the ear canal where it vibrates the eardrum and the ossicles (or ear bones). (evavarga.net)
  • Though hearing in baleen whales is not well understood, in toothed whales, instead of sound coming in through the ear canal, sound comes in through fatty tissues in the jaws which are attached to an acoustic funnel. (evavarga.net)
  • Without this funnel the sound waves would take a more direct route into the auditory canal. (governmentadda.com)
  • The pinna functions as a kind of intermediate link which makes the transition smoother and less brutal allowing more sound to pass into the auditory canal (meatus). (governmentadda.com)
  • The function of the ear canal is to transmit sound from the pinna to the eardrum. (governmentadda.com)
  • Sound (as waves) enters your ear canal and hits your ear drum. (aussiedeafkids.org.au)

Middle ear8
  • These vibrations are then transmitted to the three small bones of the middle ear (the malleus, incus and stapes), which amplify the sound vibration. (petplace.com)
  • The middle ear is an air-filled cavity that turns sound waves into vibrations and delivers them to the inner ear. (kidshealth.org)
  • They adjust thanks to the narrow Eustachian (say: yoo-STAY-she-en) tube that connects the middle ear to the back of the nose and acts as a sort of pressure valve, so the pressure stays balanced on both sides of the eardrum. (kidshealth.org)
  • In this form of hearing loss, the sound waves do not conduct adequately through the outer and middle ear mechanism. (chevychaseent.com)
  • A passage leading inwards from the pinna, channeling sound towards the middle ear. (entsinushearingcarecenter.com)
  • When the sound waves are transmitted from the eardrum to the oval window, the middle ear is functioning as an acoustic transformer amplifying the sound waves before they move on into the inner ear. (governmentadda.com)

Fleshy2
Localize sound1
  • Like the monocular and binocular cues that provided information about depth, the auditory system uses both monaural (one-eared) and binaural (two-eared) cues to localize sound. (lumenlearning.com)
Anatomy2
  • Inner Ear Anatomy The inner ear is where the sound waves are translated into types of electrical nerve impulses. (graphdiagram.com)

  • The high-frequency sounds they are attuned to are not usually found in human music. (meowa.com)
  • Low-frequency sounds are lower pitched, and high-frequency sounds are higher pitched. (lumenlearning.com)
  • At the base, closest to the oval window, the membrane is stiff and only vibrates in response to short wavelength, high frequency sounds (like the buzz of fly).The membrane becomes more flexible toward the apex, there it only vibrates in the presence of longer wavelength, low frequency sound stimulation (like the humming of a bee). (audiologicservices.com)
Frequency11
  • The filtering effect of the human pinnae preferentially selects sounds in the frequency range of human speech. (wikipedia.org)
  • In the affected frequency band - the pinna notch - the pinna creates a band-stop or notch filtering effect. (wikipedia.org)
  • While reflecting from the pinna, sound also goes through a filtering process, as well as frequency dependent amplitude modulation which adds directional information to the sound (see sound localization, head-related transfer function, pinna notch). (wikipedia.org)
  • Acoustic experts measure sound waves in a variety of ways, but sound waves are commonly described in terms of frequency and amplitude. (poly.com)
