Part of an ear examination that measures the ability of sound to reach the brain.
A general term for the complete or partial loss of the ability to hear from one or both ears.
The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.
Conditions that impair the transmission of auditory impulses and information from the level of the ear to the temporal cortices, including the sensorineural pathways.
The ability or act of sensing and transducing ACOUSTIC STIMULATION to the CENTRAL NERVOUS SYSTEM. It is also called audition.
Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)
Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.
Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.
Partial hearing loss in both ears.
Persons with any degree of loss of hearing that has an impact on their activities of daily living or that requires special assistance or intervention.
Hearing loss due to interference with the mechanical reception or amplification of sound to the COCHLEA. The interference is in the outer or middle ear involving the EAR CANAL; TYMPANIC MEMBRANE; or EAR OSSICLES.
Hearing loss in frequencies above 1000 hertz.
Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.
Procedures for correcting HEARING DISORDERS.
The audibility limit of discriminating sound intensity and pitch.
A general term for the complete loss of the ability to hear from both ears.
Sensorineural hearing loss which develops suddenly over a period of hours or a few days. It varies in severity from mild to total deafness. Sudden deafness can be due to head trauma, vascular diseases, infections, or can appear without obvious cause or warning.
Partial or complete hearing loss in one ear.
Noise present in occupational, industrial, and factory situations.
Personal devices for protection of the ears from loud or high intensity noise, water, or cold. These include earmuffs and earplugs.
The teaching or training of those individuals with hearing disability or impairment.
Electrical waves in the CEREBRAL CORTEX generated by BRAIN STEM structures in response to auditory click stimuli. These are found to be abnormal in many patients with CEREBELLOPONTINE ANGLE lesions, MULTIPLE SCLEROSIS, or other DEMYELINATING DISEASES.
Gradual bilateral hearing loss associated with aging that is due to progressive degeneration of cochlear structures and central auditory pathways. Hearing loss usually begins with the high frequencies then progresses to sounds of middle and low frequencies.
The part of the inner ear (LABYRINTH) that is concerned with hearing. It forms the anterior part of the labyrinth, as a snail-like structure that is situated almost horizontally anterior to the VESTIBULAR LABYRINTH.
A syndrome characterized by depressions that recur annually at the same time each year, usually during the winter months. Other symptoms include anxiety, irritability, decreased energy, increased appetite (carbohydrate cravings), increased duration of sleep, and weight gain. SAD (seasonal affective disorder) can be treated by daily exposure to bright artificial lights (PHOTOTHERAPY), during the season of recurrence.
Treatment of disease by exposure to light, especially by variously concentrated light rays or specific wavelengths.
A nursing specialty in which skilled nursing care is provided to patients in their homes by registered or licensed practical NURSES. Home health nursing differs from HOME NURSING in that home health nurses are licensed professionals, while home nursing involves non-professional caregivers.
A form of phototherapy using color to influence health and to treat various physical or mental disorders. The color rays may be in the visible or invisible spectrum and can be administered through colored lights or applied mentally through suggestion.
Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition.
An auditory orientation mechanism involving the emission of high frequency sounds which are reflected back to the emitter (animal).
Programs of training in medicine and medical specialties offered by hospitals for graduates of medicine to meet the requirements established by accrediting authorities.
