TympanosclerosisCrystal 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).Otitis externaCeruminous 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.StapesDim 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.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).Preauricular sinus and cystSoundBite 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.AcariasisAcoustics Research InstituteMuzzle 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.Conductive hearing lossMakyo: The term is a Zen term that means “ghost cave” or “devil’s cave.” It is a figurative reference to the kind of self-delusion that results from clinging to an experience and making a conceptual “nest” out of it for oneself.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.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.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.Place theory (hearing): Place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane. By this theory, the pitch of a musical tone is determined by the places where the membrane vibrates, based on frequencies corresponding to the tonotopic organization of the primary auditory neurons.International Journal of Audiology: The International Journal of Audiology is a peer-reviewed medical journal covering research in audiology, including psychoacoustics, anatomy, physiology, cellular and molecular biology, genetics, neuroscience, speech and hearing sciences and rehabilitation devices. It is an official journal of the British Society of Audiology, the International Society of Audiology, and the Nordic Audiological Society.Post and core: A post and core (colloquially known as a "post" or "dental post") is a type of dental restorationTranspulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.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.Quaternary ammonium cation: Quaternary ammonium cations, also known as quats, are positively charged polyatomic ions of the structure NR4+, R being an alkyl group or an aryl group. Unlike the ammonium ion (NH4+) and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution.Malassezia: Malassezia (formerly known as Pityrosporum) is a genus of fungi. Malassezia is naturally found on the skin surfaces of many animals, including humans.AudiometryBeltoneEndoanal ultrasound: Endoanal ultrasound is a type of medical investigation which images the structures of the anal canal.Brevipalpus: Brevipalpus is a genus of mites in the family Tenuipalpidae, the flat mites.Brevipalpus californicus.Tympanocentesis: 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.Electronic apex locator: 200px|right|thumbPitch spacePrimary cutaneous aspergillosis: Primary cutaneous aspergillosis is a rare skin condition most often occurring at the site of intravenous cannulas in immunosuppressed patients.Psychoacoustics: Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound (including speech and music).Vibration white finger: Vibration white finger (VWF), also known as hand-arm vibration syndrome (HAVS) or dead finger,) is a secondary form of Raynaud's syndrome, an industrial injury triggered by continuous use of vibrating hand-held machinery. Use of the term "vibration white finger" has generally been superseded in professional usage by broader concept of HAVS, although it is still used by the general public.Functional 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).
