Having lost the process, function, or power of perceiving sounds. Hearing loss may range from slight tototal deafness.(child, not able to hear, he/she became)
Measured in decibels (dB) and usually described in terms of degree of impairment for hearing conversational speech.
The condition of less than full hearing capacity. The degree of hearing loss can have different terms; hard of hearing, hearing impaired and deaf are three of the more common terms. Unless otherwise specified, hearing loss includes all of these sub-classifications.
The difference between the level of sound that can just be heard by an individual with impaired hearing and a standard level that has been determined by averaging measurements from a group of young hearing people. It is usually expressed in decibels.
partial or complete loss of hearing
a function of exposure time, the average sound level, and the peak level of very loud sounds
a loss of sound sensitivity due to an abnormality anywhere along the auditory system
A physician can determine the extent of hearing loss through a series of tests. A hearing aid or cochlear implant may improve hearing.
A congenital or acquired condition resulting in the need for development (habilitiation) or enhancement (rehabilitation) of communication skills through such strategies as lip-reading and auditory discrimination. [ Go Back
Relationship to Sarcoidosis" Nervous system effects, including hearing loss, meningitis, seizures or psychiatric disorders (for example, dementia, depression, psychosis) are possible signs of sarcoidosis..."
any of the three types of hearing loss (conductive, sensorineural, or mixed). Anything that diminishes hearing sounds.
A reduction in hearing sensitivity, or the ability to hear small sounds, that is caused by exposure to excessively loud sounds, age, illness, drugs, etc. Hearing loss can be temporary or permanent. Repeated temporary losses often lead to some amount of permanent loss.
Disruption in the normal process that may occur in either the outer, middle, or inner ear, whereby sound waves are not conducted to the inner ear, converted to electrical signals and/or nerve impulses are not transmitted to the brain to be interpreted as sound. Learn more about hearing loss.
A hearing impairment is a decrease in one's ability to hear (i.e. perceive auditory information). While some cases of hearing loss are reversible with medical treatment, many lead to a permanent disability (often called deafness). If the hearing loss occurs at a young age, interference with the acquisition of spoken language and social development may occur. Hearing aids and cochlear implants may alleviate some of the problems caused by hearing impairment, but are often insufficient. People who have hearing impairments, especially those who develop a hearing problem later in life, often require support and technical adaptations as part of the rehabilitation process.
Mercury has an affinity for the acoustic nerve, eventually resulting in hearing loss.
The inability to perceive the presence of a sound at normal hearing levels.
A term used to describe a level of hearing less than that typically heard by the general population. The range of hearing loss is characterized as shown below. The range of numbers attached to the specific word labels may vary slightly. Normal Hearing o dB to 15 dB (dB=decibel; see above) Mild Loss 16 dB to 35 dB Moderate Loss 36 dB to 50 dB Moderate/Severe Loss 51 dB to 70 dB Severe Loss 71 dB to 90 dB Profound Loss 91 dB or more
The Condition"...If the cause of the hearing loss seems to be within the brain, the person may have a magnetic resonance imaging (MRI) scan of the brain..."
