What is an audiogram?
Audiogram is a graph that visually represents someone's hearing. The graph is created by performing a hearing test in which the softest sounds that someone can hear is recorded. When these sounds are brought, the result is an audiogram. Audiograms can be compared with similar graphs from other people to learn more about something hearing and determine whether it is common for gender, scope and general status of a person. They can also be interpreted as separate documents to identify problematic areas in one's auditory rage.
The audiogram has two values. Along one axis, usually horizontal, the graph is marked with frequencies from low to high. The second axis of the decibel documents, ranging from zero decibels at the top and moving down to much louder sounds at the bottom. If all the values on the audiogram fall above the 20 decibel line, it suggests that the subject has normal hearing and can hear sounds in the extent of human Speech, the zone on the chart known as the "speech banana".
audiograms have two lines, one for the left ear and one for the right ear. The graph uses different symbols to draw values for different ears. It is important to note that testing used to generate the audiogram is in a highly controlled environment and that the real capacity of hearing may vary. The audiograms also do not reveal hearing processing problems. A person with hearing impairment may have a flawless audiogram, but still has difficulty understanding the spoken language.
One test used for the development of the audiogram is the hearing test in which the subject wears headphones and tones. The subject indicates when they hear the tone and the value is marked with the test administrator. This test is an air guide test, which means it shows how well the sounds are carried out. In the bone guide test, a sensor is placed on the mastoid bone that lifts the vibrations that move through the ear. Different results of these tests can provide guides whySomeone is experiencing hearing loss.
It is generally recommended that children be regularly checked for hearing loss, along with people in professions that exhibit them with loud sounds such as construction workers and musicians. Hearing tests should be regularly performed in healthy adults. Hearing loss is sometimes gradual and people do not have to realize that they have hearing problems.
