If you think you or a loved one may have hearing loss, you are not alone. Oftentimes people notice signs of hearing loss but do not take the steps to get it treated right away. Typically, it takes people an average of seven years to seek treatment. You may have hearing loss if:
Hearing loss can be due to several factors such as the aging process, exposure to loud noise, medications, infections, head or ear trauma, congenital (birth) or genetic factors, diseases, as well as a number of other causes. Recent data shows that about 20 percent of adults in the United States (48 million) report some degree of hearing loss. Hearing loss often occurs gradually throughout a lifetime.
If you have any symptoms of hearing loss, you should see an audiologist to have a formal hearing evaluation. This hearing test, or audiologic evaluation, is diagnostic in nature and allows the audiologist to determine the type, nature and degree of your hearing loss. Your sensitivity, acuity and accuracy to speech understanding will be assessed as well. Your audiologist may also test for speech understanding at different volume levels and in different conditions, such as noise, to provide an indication as to how successful of a candidate you will be for hearing aids.
The hearing evaluation will also include a thorough case history and a visual inspection of the ear canal and eardrum. Additional tests of middle ear function may also be performed. The results of the evaluation can be useful to a physician, if the audiologist believes your hearing loss may benefit from medical intervention.
Results of the hearing evaluation are plotted on a graph called an audiogram. The audiogram provides a visual view of your hearing test results across various pitches or frequencies, especially the ones necessary for understanding speech.
The audiogram and results from your speech understanding tests are used to create a prescription by which hearing aids are programmed, if necessary.
After you undergo a hearing evaluation, the results are plotted on a chart called an audiogram. Loudness is plotted from top to bottom. The top of the graph is very quiet and the bottom of the graph is very loud. Frequency, or pitch, from low to high, is plotted from left to right. Hearing level (HL) is measured in decibels (dB) and is described in general categories, not by percentages. The general hearing loss categories used by most hearing professionals are as follows:
