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.Autoimmune 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.StapesMuzzle 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.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.Conductive hearing lossHearing (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.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.Chinchilla: RecentCeruminous 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 externaSoundBite 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.Crandall 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.Pneumatic 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.Otolith: 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.AudiometryTranslabyrinthine 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.Vestibular 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).ICD-10 Chapter VIII: Diseases of the ear and mastoid process: == H60–H99 – Diseases of the ear and mastoid process ==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.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.Spiral 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").Indian Genetic Disease DatabaseGodflesh discography: The following is a comprehensive discography of Godflesh, an English industrial metal band.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.TympanoplastyNoise-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.Masakazu Konishi: Gruber Prize in Neuroscience Yamashina AwardSound changeCROS hearing aid: A Contralateral Routing Of Signals (CROS)Harford, E., Barry, J.United States Animal Identification Plan: United States Animal Identification Plan (USAIP) — Officials from approximately 70 animal industry organizations and government agencies have been working since early 2002 on a plan for a national system to identify that might follow food animals from birth to slaughter. The primary purpose is to trace animals back from slaughter through all premises within 48 hours of an animal disease outbreak, in order to determine the disease’s origin and to contain it quickly.Utricle (ear)Otto DeitersOtitis media: suppurativeEndolymphatic 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).Rande Lazar: Rande Lazar is an otolaryngologist with a primary focus in pediatric ear, nose, and throat disorders.

This is understood as the process by which the human auditory system organizes sound into perceptually meaningful elements.Peripheral edemaOtosclerosisLabyrinthitisFF 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.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.Auditory event: Auditory events describe the subjective perception, when listening to a certain sound situation. This term was introduced by Jens Blauert (Ruhr-University Bochum) in 1966, in order to distinguish clearly between the physical sound field and the auditory perception of the sound.Acoustics Research Institute
