Eardrum In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles. Rupture or perforation of the eardrum can lead to conductive hearing loss. Collapse or retraction

stimuli. In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog’s ear drum works in very much the same way as does a human ear drum. It is a membrane that is stretched across a ring of cartilage like a snare drum that vibrates. Crossing the middle ear chamber there is an ossicle

The specific style of tap that he performed and later taught to students was called “scientific rhythm.” Brown explained, “You heard all this music and rhythm but couldn’t see where it was coming from.” Eddie Brown’s natural propensity to hear and create intricate rhythms allowed him to make his mark on the world of tap dance: “A good ear ain’t good or bad, but a good ear is what you need. That’s why tap is scientific.” Eddie Brown (dancer) Eddie Brown, was a dancer born in 1918 in Omaha, Nebraska.

With a new age of pop music on the rise within the past decade, it is easy to assume the drum set has been replaced by electronic sounds produced by an engineer. In reality, the drum set is the reason behind the production of these electronic beats, and live drummers contribute to modern day hip-hop much more than what meets the ear.

Weber test The Weber test is a quick screening test for hearing. It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). The test is named after Ernst Heinrich Weber (1795–1878). Conductive hearing ability is mediated by the middle ear composed of the ossicles: incus, malleus, stapes. Sensorineural hearing ability is mediated by the inner ear composed of the cochlea with its internal basilar membrane and attached cochlear nerve (cranial nerve VIII). The outer ear consisting of the pinna, ear canal, and ear drum or tympanic membrane transmits sounds

This new membrane technology can be retrofitted and applied to existing headphones. A film of medical-grade polymer (ePTFE) is stretched over a hole, essentially acting as a membrane to help absorb pressure buildup in the ear drum. Another alternative developed by Asius is a seal called the Ambrose Diaphonic Ear Lens (ADEL). The seal attaches to headphones or hearing aids and is inflated like a balloon and acts as an

Dr. Williams also examined the right ear and found that it was not in as bad a condition as he had anticipated. He therefore decided to operate on the left ear instead of the right, performing an ossiculectomy, removing a part of the drum membrane and scraping away the diseased portion of the inner ear. Mrs. Mohr later brought suit against Dr. Williams, claiming that he

are usually middle ear epidermal cysts that are identified deep within an intact ear drum. Keratin-filled cysts that grow medial to the tympanic membrane are considered to be congenital if they fulfill the following criteria (levenson's criteria): Congenital cholesteatomas occur at three important sites: the middle ear, the Petrous apex, and the cerebropontine angle. They are most often found deep to the anterior aspect of the ear drum, and a vestigial structure, the epidermoid formation, from which congenital cholesteatoma may originate, has been identified in this area. Not all middle ear epidermal cysts are congenital, as they can be acquired

Alternobaric vertigo is most pronounced when the diver is in the vertical position; the spinning is towards the ear with the higher pressure and tends to develop when the pressures differ by 60 cm of water or more. Ear clearing may be a remedy. A similar vertigo can also occur as a result of unequal heating stimulation of one inner ear labyrinth over the other due to diving in a prone position in cold water - the undermost ear being stimulated.

Analog ear An analog ear or analog cochlea is a model of the ear or of the cochlea (in the inner ear) based on an electrical, electronic or mechanical analog. An analog ear is commonly described as an interconnection of electrical elements such as resistors, capacitors, and inductors; sometimes transformers and active amplifiers are included. The ear of the typical mammal consists of three parts. The outer ear collects sounds like a horn and guides them to the eardrum. Vibrations of the drum are conveyed to the inner ear via a system of bones called ossicles. These leverage the larger

the middle-ear muscles. The middle ear is hollow. In a high-altitude environment or on diving into water, there will be a pressure difference between the middle ear and the outside environment. This pressure will pose a risk of bursting or otherwise damaging the tympanum if it is not relieved. If middle ear pressure remains low, the ear drum may become retracted into the middle ear <nowiki>. One of the functions of the </nowiki>Eustachian tubes that connect the middle ear to the nasopharynx is to help keep middle ear pressure the same as air pressure.

providing. The traditional method of real ear measurement is known as insertion gain, which is the difference between the sound pressure level measured near the ear drum with a hearing aid in place, and the sound pressure level measured in the unaided ear. First a measurement is made with the probe tube in the open ear (Real Ear Unaided Response, or REUR), then a second one is made using the same test signal with the hearing aid in place and turned on (Real Ear Aided Response, or REAR). The difference between these two results is the insertion gain. This gain

a blood tonic. Modern research into possible medical applications has variously concluded that "A. auricula-judae" has antitumour, hypoglycemic, anticoagulant and cholesterol-lowering properties. The medieval Latin name "auricula Judae" (Judas's Ear) matches the vernacular name in most European languages (c.f. French "oreille de Judas", German "Judasohr"). The translation "Jew's Ear" appeared in English by 1544. The species was first mentioned in the scientific literature as "Tremella auricula" by Carl Linnaeus in his 1753 "Species Plantarum", and later (1789) described by Jean Baptiste François Pierre Bulliard as "Tremella auricula-judae". However, the genus "Tremella" is now reserved for fungal species that live as

ear and throat. The primary function of the middle ear is to efficiently transfer acoustic energy from compression waves in air to fluid–membrane waves within the cochlea. The middle ear contains three tiny bones known as the ossicles: "malleus", "incus", and "stapes". The ossicles were given their Latin names for their distinctive shapes; they are also referred to as the "hammer", "anvil", and "stirrup", respectively. The ossicles directly couple sound energy from the ear drum to the oval window of the cochlea. While the stapes is present in all tetrapods, the malleus and incus evolved from lower and upper jaw

allowing the pus in the middle-ear space to drain into the ear canal. If there is enough, this drainage may be obvious. Even though the perforation of the tympanic membrane suggests a highly painful and traumatic process, it is almost always associated with a dramatic relief of pressure and pain. In a simple case of acute otitis media in an otherwise healthy person, the body's defenses are likely to resolve the infection and the ear drum nearly always heals. An option for severe acute otitis media in which analgesics are not controlling ear pain is to perform a tympanocentesis, i.e.,

in the seventh week of development the auditory tube begins to form out of the tympanic membrane. The human ear is divided into three sections. Each section has possesses its own specialized function. 1. The outer ear acts like a funnel and takes in the sound. 2. The middle ear holds the tympanic membrane, or ear drum and several little bones that are moved by the sound waves that have entered the ear via the canal. These movements are very small, like vibrations and are transmitted to the inner ear. 3. The inner ear contains a structure called the cochlea,

Other complications included otitis externa (swimmer's ear), which involves inflammation or bacterial infection of the external acoustic meatus, as well as pain, vertigo, tinnitus, and perforation of the ear drum. Based on this study, a rate of major complications in 1/1000 ears syringed was suggested. Claims arising from ear syringing mishaps account for about 25% of the total claims received by New Zealand's Accident Compensation Corporation ENT Medical Misadventure Committee.

auditory system, it is necessary to view parts of the biological auditory system in terms of known physical models. Consisting of three areas, the outer, middle and inner ear, the auditory periphery acts as a complex transducer that converts sound vibrations into action potentials in the auditory nerve. The outer ear consists of the external ear, ear canal and the ear drum. The outer ear, like an acoustic funnel, helps locating the sound source. The ear canal acts as a resonant tube (like an organ pipe) to amplify frequencies between 2–5.5 kHz with a maximum amplification of about 11 dB

ear drum may become perforated in the event of a large sound or explosion, when diving or flying (called barotrauma), or by objects inserted into the ear. Another common cause of injury is due to an infection such as otitis media. These may cause a discharge from the ear called otorrhea, and are often investigated by otoscopy and audiometry. Treatment may include watchful waiting, antibiotics and possibly surgery, if the injury is prolonged or the position of the ossicles is affected.

Cerumenolytics should not be used ears that in which the ear drum has been perforated or is otherwise nonintact. Cerumenolytics should also be avoided in ears that are actively infected due to the lack of research in this area (i.e. people suffering from otitis externa, a type of ear infection). In general, cerumenolytics can cause ear discomfort, transient loss of hearing, dizziness, and local irritation. Local reactions are least frequent with cerumenolytics that lack

Otosclerosis Otosclerosis or otospongiosis is an abnormal growth of bone near the middle ear. It can result in hearing loss. The term otosclerosis is something of a misnomer. Much of the clinical course is characterised by lucent rather than sclerotic bony changes, hence it is also known as otospongiosis. This is an inherited disease. The primary form of hearing loss in otosclerosis is conductive hearing loss (CHL) whereby sounds reach the ear drum but are incompletely transferred via the ossicular chain in the middle ear, and thus partly fail to reach the inner ear (cochlea). This usually will begin in

The color of the candle wax matches the light brown-colored wax of the human ear, making the distinction between the two waxes more difficult for a layperson. Because the candle itself is a hollow tube, some of the hot burnt wax could drop down inside the candle, into the ear canal, potentially injuring the eardrum.

The Rinne test, in which a patient is asked to say whether a vibrating tuning fork is heard more loudly adjacent to the ear canal (air conduction) or touching the bone behind the ear (bone conduction), is negative indicating that bone conduction is more effective that air conduction. A normal, or positive, result, is when air conduction is more effective than bone conduction. With a one-sided conductive component the combined

Animals with the ability to localize sound have a clear evolutionary advantage. Sound is the perceptual result of mechanical vibrations traveling through a medium such as air or water. Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exterior ear, and enter the ear canal.

and is called tonic tensor tympani syndrome (TTTS). In some people with hyperacusis, the tensor tympani muscle can contract just by thinking about a loud sound. Following exposure to intolerable sounds, this contraction of the tensor tympani muscle tightens the ear drum, which can lead to the symptoms of ear pain/a fluttering sensation/a sensation of fullness in the ear (in the absence of any middle or inner ear pathology). The mechanisms behind dysfunction of the tympanic tensor muscle and their consequences are hypotheses. However, in a published study, researchers studied the case of an acoustic shock whose mechanisms suggest dysfunction

The scientific name for the order, "Dermaptera", is Greek in origin, stemming from the words "derma", meaning skin, and "pteron" (plural "ptera"), wing. It was coined by Charles De Geer in 1773. The common term, "earwig," is derived from the Old English "," which means "ear", and "," which means "insect", or literally, "beetle".

is unable to process speech information. Mixed hearing loss is a combination of conductive and sensorineural hearing loss. Chronic ear infection (a fairly common diagnosis) can cause a defective ear drum or middle-ear ossicle damages, or both. In addition to the conductive loss, a sensory component may be present. This is not an actual hearing loss but gives rise to significant difficulties in hearing. One kind of auditory processing disorder is King-Kopetzky syndrome, which is characterized by an inability to process out background noise in noisy environments despite normal performance on traditional hearing tests.

stages into which paleontologists divide the evolution towards the mammalian anatomy. In modern amniotes (including mammals), the middle ear collects airborne sounds through an ear drum and transmits the vibrations to the inner ear via thin cartilaginous and ossified structures, which usually include the stapes (a stirrup-shaped auditory ossicle). But the earliest tetrapods, amphibians and amniotes probably did not have ear drums. In fact ear drums apparently evolved independently three to six times, in: stegocephalians (very primitive amphibians); in anurans (the amphibian group that includes frogs and toads); in synapsids (mammals and their extinct relatives), in diapsids (the most important

NAME is a benign glandular neoplasm of middle ear showing histologic and immunohistochemical neuroendocrine and mucin-secreting differentiation (biphasic or dual differentiation). Neuroendocrine adenoma of the middle ear has gone by several different names, including middle ear adenoma, carcinoid tumor, amphicrine adenoma, adenocarcinoid, and adenomatoid tumor of middle ear. The various names have created some confusion about this uncommon middle ear tumor. Regardless of the name applied, the "middle ear" anatomic site must be known or confirmed. This uncommon tumor

Patulous Eustachian tube Patulous Eustachian tube, also known as patent Eustachian tube or PET, is the name of a physical disorder where the Eustachian tube, which is normally closed, instead stays intermittently open. When this occurs, the patient experiences autophony, the hearing of self-generated sounds. These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and can create a "bucket on the head" effect.

Because of the change, a change in light intensity causes the response of the rods to be much slower than expected (for a process associated with the nervous system). In the auditory system, sound vibrations (mechanical energy) are transduced into electrical energy by hair cells in the inner ear.

times fainter than the sounds they emit. To avoid deafening themselves, whenever a bat makes an echolocation emission, a small muscle in the bat's middle ear (the stapedius muscle) clamps down on small bones called ossicles, which normally amplify sounds between the ear drum and the cochlea. This dampens the intensity of the sounds that the bat hears during this time, preserving hearing sensitivity to target echoes. Jamming can occur if an animal is still producing a sound when an echo returns, for example, from a nearby object. Bats avoid this type of jamming by producing short sounds of 3-50
