Document Summary
Amount of loss (where is the individual struggling to hear and how much, pattern of loss (struggling with high or low frequency loss) Other descriptors associated with hearing loss are: bilateral versus unilateral, bilateral-both ears. Symmetrical versus asymmetrical: symmetrical-degree and configuration of hearing loss are the same in each ear. Asymmetrical-degree and configuration of hearing loss are different in each ear: progressive versus sudden hearing loss, progressive hearing loss becomes worse over time. Such a hearing loss requires immediate medical attention to determine its cause and treatment. (ex: tumor pressing on your eighth nerve and affecting your hearing) Fluctuating versus stable hearing loss: fluctuating-hearing loss that changes over time- sometimes getting better, sometimes getting worse. The audiogram: audiogram - a graph showing the results of the pure-tone hearing tests; illustrates the type, degree, and configuration of hearing loss. Pitch or frequency: x axis - each vertical line from left to right represents a pitch, or frequency, in hertz (hz).
