Children with spatial hearing loss commonly present with difficulties understanding speech in the classroom. [1] Spatial hearing loss is found in most people over 70 years of age, and can sometimes be independent of other types of age related hearing loss. [2] As with presbycusis, spatial hearing loss varies with age. Through childhood and into ...
Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people. [8]
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
This argument, however, was refuted by Bonvicini [15] (1905), who measured the hearing of an auditory agnosia patient with tuning forks, and confirmed intact pure tone perception. Similarly, Barrett's aphasic patient, [16] who was incapable of comprehending speech, had intact hearing thresholds when examined with tuning forks and with a Galton ...
Similar, but distinct, is color agnosia, which involves having difficulty recognizing colors, while still being able to perceive them as measured by a color matching or categorizing task. [12] Cortical deafness: Refers to people who do not perceive any auditory information but whose hearing is intact. Environmental agnosia
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [5] The National Institute for Occupational Safety and Health (NIOSH) recognizes that the majority of hearing loss is not due to age, but due to noise exposure.
The first symptom of NIHL may be difficulty hearing a conversation against a noisy background. [7] The effect of hearing loss on speech perception has two components. The first component is the loss of audibility, which may be perceived as an overall decrease in volume. Modern hearing aids compensate this loss with amplification.
