Frequency is plotted at the top of the graph, ranging from low frequencies(250 Hz) on the left to high frequencies (8000 Hz) on the right. The graph to the left represents a blank audiogram illustrates the degrees of hearing loss listed above. The list below outlines different hearing loss thresholds as they are determined in relation to an individual with a normal hearing threshold. For example, persons with mild hearing loss have thresholds that are 25 to 40 dB higher than the thresholds for those with normal hearing when tested using different at several frequencies. The degree of hearing loss is expressed by the difference between a person’s threshold and the average threshold for people with normal sensitivity. During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear. The decibel (or dB) is the unit of intensity used to describe hearing sensitivity. Hearing thresholds are defined as the lowest level sound that can be heard 50% of the time. In order to determine a person’s degree of hearing loss, their hearing thresholds must be determined. The amount (or degree) of hearing loss a person experiences is based on hearing sensitivity. to noon and 1 to 4 p.m.What information is on an audiogram and what does it mean for the person’s hearing ability? in Fairfield, is open Monday through Friday from 9 a.m. Reach him at 784-6950 or The Solano County Veteran Services Office, 675 Texas St. Ted Puntillo is director of Veteran Services for Solano County. A hearing test from a hearing center or your physician is recommended. A letter from your spouse will not be sufficient. You will need to bring your DD-214 (discharge) and some type of diagnosis that you do have hearing loss. If you were exposed to high levels of auditory trauma while you were in the military and have developed tinnitus since the service time or a documented hearing loss, we recommend that you come into our office. Service members are provided the best hearing protection available and are tested regularly if they are in a high noise environment. Today the military is very conscious of noise exposure. In the 1960s going to the rifle range for hours and shooting hundreds of rounds with absolutely no hearing protection was normal. Until the mid-1970s very little hearing protection was used in the military. Combat veterans are usually exposed to extended periods of auditory trauma from the noises of war. Aircraft carriers, flight line jobs, infantry, artillery and naval ship engine rooms are some of the loudest environments in the military. Most veterans have been exposed to these types of decibels for an extended period of time. Artillery is upwards of the 185 decibel range and jet engines will give out 140 decibels. Using a rifle or fire arm in the service will generate decibels in the 150 decibel range. In the military noise exposure is common. For example, the voices of women and children are hard to hear for a person with noise-induced hearing loss. An inability to hear high-pitched voices and sounds are a sign that you may have noise induced hearing loss. High-frequency hearing loss is normally the first symptom of this type of noise-induced hearing loss. Anything above 85 decibels for a prolonged time will most likely cause hearing damage eventually. Noise-induced hearing loss is caused by sustained exposure to dangerous levels of sound. Sensorineural hearing loss can be caused by many things, but the primary cause for veterans is unprotected noise exposure and head trauma. Senorineural hearing loss is caused by damage to the inner ear (cochlea) or the retrocochlea nerves (nerves that connect the ear to the brain). It is usually caused by temporary factors, including illnesses or some medications used to treat other conditions, and does not usually result in total hearing loss. Conductive hearing loss is caused by damage to the outer or middle ear and usually can be repaired or will heal over time. There are three types of hearing loss: conductive hearing loss, sensorineural hearing loss and mixed hearing loss. Both of these conditions affect the person’s ability to hear sounds and speech in particular. Tinnitus can be a ringing, buzzing, crackling or humming sound in your ears. Hearing loss is fairly self explanatory in that it is the loss of the ability to hear sounds. Hearing loss and tinnitus are the most common disabilities that occur in the veteran population.
