If you are interested in tinnitus, as well as hyperacusis, you will want to also peruse the Page devoted to Tinnitus. Hyperacusis (intolerance to loud but everyday sounds) is not uncommon. Sometimes hyperacusis is exclusively an auditory problem. However it can also be a symptom associated with neurological and other medical disorders. Fortunately, hyperacusis can be diagnosed and successfully managed. The information available on this Page will serve as an introduction to the topic. The information on hyperacusis available in the nearby PPT presentation is summarized by the following abstract and learning objectives:
Abstract: Most audiologists occasionally encounter patients who present with the primary complaint of sensitivity to loud sounds. Hyperacusis can be a serious problem that markedly affects quality of life. Children with hyperacusis may have difficulty tolerating everyday sounds in and outside of school. Family members, and health care professionals, are frustrated by the child's problem, and their inability to provide help. Because of their hyperacusis, adults may not be able to continue working in noisy environments. Quality of life deteriorates, and family dynamics are adversely affected.
In this 1-hour presentation will be given in three portions. I first define hyperacusis, summarize demographics of the disorder, and review the literature on basic mechanisms of hyperacusis, e.g., neuro-chemical imbalance, efferent auditory system dysfunction, and inappropriate central nervous system response to peripheral stimulation. Recent research auditory neuroscience in general, and on tinnitus in particular, has led to some plausible theories on the causes of hyperacusis. Approximately one-third of the time is devoted to the presentation of a clinically feasible protocol for audiologic assessment of hyperacusis. Audiologic management strategies are discussed in the final segment of the presentation, followed by case reports to reinforce main points.
