Crystal earpiece: A crystal earpiece, is a type of piezoelectric earphone, producing sound by using a piezoelectric crystal, a material that changes its shape when electricity is applied to it. It is usually designed to plug into the ear canal of the user.Neuroendocrine adenoma middle ear: Neuroendocrine adenoma of the middle ear (NAME) is a tumor which arises from a specific anatomic site: middle ear. NAME is a benign glandular neoplasm of middle ear showing histologic and immunohistochemical neuroendocrine and mucin-secreting differentiation (biphasic or dual differentiation).Preauricular sinus and cystFunctional disorder: A functional disorder is a medical condition that impairs the normal function of a bodily process, but where every part of the body looks completely normal under examination, dissection or even under a microscope. This stands in contrast to a structural disorder (in which some part of the body can be seen to be abnormal) or a psychosomatic disorder (in which symptoms are caused by psychological or psychiatric illness).CholesteatomaTympanosclerosisAutoimmune inner ear disease: Autoimmune inner ear disease is a suspected autoimmune disease characterized by rapidly progressive bilateral sensorineural hearing loss.Inner Ear, Autoimmune (eMedicine, 2006) It occurs when the body's immune system attacks cells in the inner ear that are mistaken for a virus or bacteria.Perichondritis: Perichondritis is inflammation of the perichondrium, a layer of connective tissue which surrounds cartilage. A common form, auricular perichondritis (perichondritis auriculae) involves infection of the pinna due to infection of traumatic or surgical wound or the spread of inflammation into depth.Equivalent rectangular bandwidth: The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters.Jeff Elbel: Jeff Elbel is an American musician, songwriter, and producer currently based near Chicago, Illinois. He is also a frequent journalist for publications including the Chicago Sun-Times.Tympanostomy tubeTympanocentesis: Tympanocentesis is the drainage of fluid from the middle ear usually caused by otitis media, by using a small-gauge needle to puncture the tympanic membrane, also known as the eardrum.Hearing (person): The term hearing or hearing person, from the perspective of mainstream English-language culture, refers to someone whose sense of hearing is at the medical norm. From this point of view, someone who is not fully hearing has a hearing loss or is said to be hard of hearing or deaf.Eagle syndrome: Eagle syndrome (also termed stylohyoid syndrome styloid syndrome, styloid-stylohyoid syndrome, or styloid–carotid artery syndrome) is a rare condition caused by an elongated or deviated styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures giving rise to pain.Dim spot: In reflection seismology, a dim spot is a local low amplitude seismic attribute anomaly that can indicate the presence of hydrocarbonsSchlumberger: Oilfield Glossary and is therefore known as a direct hydrocarbon indicator. It primarily results from the decrease in acoustic impedance contrast when a hydrocarbon (with a low acoustic impedance) replaces the brine-saturated zone (with a high acoustic impedance) that underlies a shale (with the lowest acoustic impedance of the three), decreasing the reflection coefficient.StapesCrandall syndrome: Crandall syndrome is a very rare congenital disorder characterised by progressive sensorineural hearing loss, hair loss associated with pili torti, and hypogonadism demonstrated through low levels of luteinising hormone and growth hormone. It is thought to be an autosomal recessive disorder closely related to Björnstad syndrome which presents similarly but without hypogonadism.Renal medullaConductive hearing lossOtolith: An otolith (οτο-, oto-, ear + λιθος, lithos, a stone), also called statoconium or otoconium, is a structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. They have been identified in both extinct and extant vertebrates.Chinchilla: RecentVestibular system: The vestibular system, in most mammals, is the sensory system that provides the leading contribution about the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals, situated in the vestibulum in the inner ear (Figure 1).Muzzle brake: A muzzle brake or recoil compensator is a device connected to the muzzle of a firearm or cannon that redirects propellant gases to counter recoil and unwanted rising of the barrel during rapid fire.Muzzle brake in the NRA Firearms Glossary The concept was introduced for artillery and was a common feature on many anti-tank guns, especially those in tanks, in order to reduce the area needed to take up the recoil stroke.Prelingual deafness: A prelingual deaf individual is someone who was born with a hearing loss, or whose hearing loss occurred before they began to speak. Infants usually start saying their first words around one year.Frequency following response: Frequency following response (FFR), also referred to as Frequency Following Potential (FFP), is an evoked potential generated by periodic or nearly-periodic auditory stimuli.Burkard, R.Perilymph: Perilymph (also known as Cotunnius' liquid, and liquor cotunnii) is an extracellular fluid located within the cochlea (part of the inner ear) in two of its three compartments: the scala tympani and scala vestibuli. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid.Retinal regeneration: Retinal regeneration deals with restoring retinal function to vertebrates so impaired.SoundBite Hearing System: SoundBite Hearing System is a non-surgical bone conduction prosthetic device that transmits sound via the teeth. It is an alternative to surgical bone conduction prosthetic devices, which require surgical implantation into the skull to conduct sound.Guttural pouch: In the equids (horse family) and some species such as the desert hyrax, the guttural pouch is one of a pair of air chambers in the neck just behind the skull and below the ears. These pouches are on both sides of the head and are air-filled out-pouchings or evaginations to the Eustachian tube, leading into the nasopharynx.Otto DeitersMembrane protein: Membrane proteins are proteins that interact with biological membranes. They are one of the common types of protein along with soluble globular proteins, fibrous proteins, and disordered proteins.Utricle (ear)Ceruminous gland: Ceruminous glands are specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal. Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory layer of cells and an outer myoepithelial layer of cells.Otitis externaPneumatic otoscopy: The pneumatic otoscope is the standard tool used in diagnosing otitis media. In addition to the pneumatic (diagnostic) head, a surgical head also is useful.Mitochondrion: The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek , , i.AudiometryIndian Genetic Disease DatabaseEndolymphatic sac tumor: An endolymphatic sac tumor is a very uncommon papillary epithelial neoplasm arising within the endolymphatic sac or endolymphatic duct. This tumor shows a very high association with von Hippel-Lindau syndrome (VHL).Translabyrinthine approach: The translabyrinthine approach is a surgical approach to the cerebellopontine angle, or CPA. It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.Tripartite ATP-independent periplasmic transporter: Tripartite ATP-independent periplasmic transporters (TRAP transporters) are a large family of solute transporters found in bacteria and archaea, but not in eukaryotes, that appear to be specific for the uptake of organic acids. They are unique in that they utilize a substrate binding protein (SBP) in combination with a secondary transporter.Noise-induced hearing loss: Noise-induced hearing loss (NIHL) is hearing impairment resulting from exposure to high decibel (loud) sound that may exhibit as loss of a narrow range of frequencies, impaired cognitive perception of sound or other impairment, including hyperacusis or tinnitus. Hearing may deteriorate gradually from chronic and repeated noise exposure, such as loud music or background noise, or suddenly, from an acute, high intensity noise incident including gunshots and airhorns.Hair cell: Hair cells are the sensory receptors of both the auditory system and the vestibular system in all vertebrates. Through mechanotransduction, hair cells detect movement in their environment.ICD-10 Chapter VIII: Diseases of the ear and mastoid process: == H60–H99 – Diseases of the ear and mastoid process ==Low-voltage electron microscope: Low-voltage electron microscope (LVEM) is an electron microscope which operates at accelerating voltages of a few kiloelectronvolts or less. While the low voltage electron microscopy technique will never replace conventional high voltage electron microscopes, it is quickly becoming appreciated for many different disciplines.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.Coles PhillipsSound changeSilent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Matrix model: == Mathematics and physics ==Cell membraneDog healthSpiral pumpNachzehrer: A nachzehrer is a sort of German vampire. Nachzehrer translates "after (nach) living off (zehre)" likely alluding to their living after death or living off humans after death in addition to the choice of "nach" for "after" which is similar to "nacht" ("night").FF Scala: FF Scala is an old style, humanist, serif typeface designed by Dutch typeface designer Martin Majoor in 1990 for the Muziekcentrum Vredenburg in Utrecht, the Netherlands. The FF Scala font family was named for the Teatro alla Scala (1776–78) in Milan, Italy.Godflesh discography: The following is a comprehensive discography of Godflesh, an English industrial metal band.LabyrinthitisMorphant: An organism which has been treated with a morpholino antisense oligo to temporarily knock down expression of a targeted gene is called a morphant.TympanoplastyVestibulocochlear dysfunction progressive familial: Vestibulocochlear dysfunction progressive familial, known also as familial progressive vestibulocochlear dysfunction is an autosomal dominant disease that results in sensorineural hearing loss and vestibular areflexia. Patients report feelings of vague dissiness, blurred vision, dysequilibrium in the dark, and progressive hearing impairment.Immunosurgery: Immunosurgery is a method of removing an external cell layer of an object. Immunosurgery is to expose the specimen to a solution containing antibodies against the object, remove that solution and subsequently expose the object to complement.Masakazu Konishi: Gruber Prize in Neuroscience Yamashina Award
