Types of Audiometry Tests
by Time Andx office automation systemsA hearing
test is usually done by an audiologist with an audiogram and provides an
accurate reading of an individual's hearing capacity. An audiogram measures the
ability of a person to detect sounds within a sound wave by measuring the time
the sound takes to rise or fall from its original level. There are other
audible testing procedures too, e.g., Weber auditory test and Rinne auditory
test.
Audiometers
are used in detecting hearing loss when there is cochlea damage in the outer
ear, inner ear or middle ear. The damage could be caused by infections, carious
diseases, microscopic hearing deformities and tumors. The damaged part of the
eardrum has nerve endings that convey messages from the brain and allow the person
to distinguish external sounds. When this part of the ear becomes damaged, it
becomes unable to distinguish between sounds that come from the environment and
ones that it has grown accustomed to.
Audiometers
cannot detect all sounds that people can hear, such as speech. It is the job of
an audiologist to combine the patient's answers to this questionnaire with the
patient's response to specific sounds in order to conduct hearing test. The
person should hear a word or a phrase and then the person should hear it on the
appropriate frequency. The person should respond to the question or to the
sound, indicating what type of hearing problem he or she may have.
During a
hearing test, the patient will lie down on a table under a piece of equipment
called an audiogram. A hearing care professional will attach a device, called
an auditory probe, to the front part of the earlobe. This probe can move about
in the ear canal with the audiologist's hands free. The probe then produces an
auditory signal that is converted into a sound that the patient can hear.
There are
two types of audiometry tests used in hearing test: patch and free biopsy.
Patch tests are most often done on children, while free biopsies are usually
done on adults. In a patch exam, the audiologist inserts a translucent plug
called an insertion guide into each ear. He or she places the probe over the
area of interest, which is evaluated using a computer, and takes an auditory
measurement.
A hearing
test that uses patch exams is called audiometry evaluation. The probe moves
slowly through the outer and middle ear to listen to the inside sounds. A sound
that the audiologist hears is interpreted by the person as consisting of three
components. These are reflected in the pitch, the intensity, and the rhythm of
the sound. This evaluation allows doctors to determine if patients have
permanent or temporary hearing loss.
With a free biopsy, the health care provider cannot determine how severe the hearing loss is. Instead, he or she determines if sounds are louder or softer than they normally would be in that particular person. The audiologist uses this information to perform a variety of tasks hearing aid Pakistan. Among other things, he or she places the finger in each ear and plays tones at the same volume into each, comparing the sounds to a standard audiogram.
If you or your child has experienced or are experiencing hearing loss, it's important to visit an audiologist. Early detection of hearing problems helps to prevent further hearing damage. If you or your child is experiencing moderate to severe hearing loss or deafness, you should discuss the options with a hearing health professional. Audiometry exams are very helpful for detecting hearing problems and for providing a detailed medical history. Early detection can make a tremendous difference in the course of hearing loss treatmentSponsor Ads
