An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. The closer the marks are to the top of the graph, the softer the sounds that person can hear. Where the patient's results fall on the audiogram indicate the different degrees of hearing loss.Screening audiometry presents tones across the speech spectrum (500 to 4, 000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children). 17 Results are normal audiogram examples
Lets look at an example. In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to
Example normal audiogram (more examples are at the end) The dB score is not really percent loss, but neverthless 100 dB hearing loss is nearly equivalent to complete deafness for that particular frequency. A score of 0 is normal. It is possible to have scores less than 0, which indicate better than average hearing. Audiograms present our ability to hear plotted on a graph. You can obtain an audiogram by completing a hearing test. These graphed results reveal how well people responded to sounds and can be used to identify hearing loss.normal audiogram examples Audiometry and Hearing Loss Examples. An audiogram shows the quietest sounds you can just hear. the blue crosses represent the left ear. lower pitched sounds on the left going to higher pitched sounds on the right. cross represents the individual frequencies of sound that have been presented.
For example, on the top audiogram, the hearing levels for the low to mid pitches are within normal limits. However, the hearing levels for the high pitch sounds fall outside of normal to a moderate hearing loss. normal audiogram examples How can the answer be improved?
