An abnormally disproportionate increase in the sensation of loudness in response to auditory stimuli of normal volume. COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; FACIAL NERVE DISEASES; STAPES SURGERY; and other disorders may be associated with this condition.

A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.

A short muscle that arises from the pharyngotympanic tube (EUSTACHIAN TUBE) and inserts into the handle of the MALLEUS. This muscle pulls the handle medially thus controlling the tension and movement of TYMPANIC MEMBRANE.

An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.

The audibility limit of discriminating sound intensity and pitch.

Any sound which is unwanted or interferes with HEARING other sounds.

The study of the structure, growth, activities, and functions of NEURONS and the NERVOUS SYSTEM.

Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).

Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.

A complex involuntary response to an unexpected strong stimulus usually auditory in nature.

Application of principles and practices of engineering science to biomedical research and health care.

A syndrome characterized by severe burning pain in an extremity accompanied by sudomotor, vasomotor, and trophic changes in bone without an associated specific nerve injury. This condition is most often precipitated by trauma to soft tissue or nerve complexes. The skin over the affected region is usually erythematous and demonstrates hypersensitivity to tactile stimuli and erythema. (Adams et al., Principles of Neurology, 6th ed, p1360; Pain 1995 Oct;63(1):127-33)

The perceived attribute of a sound which corresponds to the physical attribute of intensity.

I'm sorry for any confusion, but the term "Oregon" is a geographical location and not a medical concept or condition. It is a state in the Pacific Northwest region of the United States. If you have any questions related to medical topics, I would be happy to help answer those!

The study of hearing and hearing impairment.

A genus of gram-negative, oxidase-positive, nonfermentative rods which are motile by means of a single flagellum. Afipia felis and BARTONELLA HENSELAE are causative agents of CAT-SCRATCH DISEASE. (From Bergey's Manual of Determinative Bacteriology, 9th ed)

Educational programs for individuals who have been inactive in their profession, or who wish to regain unused skills.

State plans prepared by the State Health Planning and Development Agencies which are made up from plans submitted by the Health Systems Agencies and subject to review and revision by the Statewide Health Coordinating Council.
