2. If you have hearing loss problems, then an audiometer is
the best device to evaluate to what extend your problem
is. This device can also be used to test other problems
specifically those that involve the Ear, nose or the
throat. This device is calibrated in decibel units which
are universally accepted. The calibration is however
done in regular basis to ensure that the device gives a
perfect reading when in use.
3. The audiometer resembles a pair of headphones. It is
connected to a computer which controls its operation. A
special button, which gives feedback signals as received
from the patient, is also embedded in the device. During
operation, the response of a patient to different
frequencies is displayed in the computer which is
subsequently used to plot an audiogram. The audiogram
is keenly analyzed to determine the range which a
patient can react to different sound frequencies.
4. An audiogram is basically a graph of the intensity of the
sound in decibels against the reaction frequency in
hertz. This graph is drawn with the aid of a computer.
The graph will then be analyzed carefully by a medical
specialist to determine at what range the patient is able
to react to the sound frequencies. This will guide the
specialist in administering treatment to the patient.
5. There exist two types of audiometers. They are the
software and the hardware type. The software type is
also called the digital audiometers. Such devices use
computer software in their operation. They are mostly
used by speech therapists in educational institutions to
guide students with hearing capabilities.
6. The hardware type is a bit complex. It requires an
experienced person to use it. It comes with an
embedded control unit and a feedback button as well. It
requires a special type of a computer application to
display its results. This device is relatively expensive. It is
found in referral hospitals and research labs.
7. The hearing loss procedure is diagnosed by presenting a
patient with a sound from the audiometer but being
varied in frequency. Their reactions to this sound of
different frequencies will be noted down. It is these
frequencies which are used to plot the audiogram. The
medical specialist will then study the audiogram to
determine the intensity of hearing loss of the patient.
8. During hearing loss analysis, the way through which
patients respond to the sound varies. Adult patients are
required to press a button while small children are
provided with toys to show their reactions to the sound.
Head turn can also be used to note a reaction to the
sound.
9. Hearing loss problems are not suffered by human
beings. Animals do also suffer from this problem. An
audiometer is still the device veterinary doctors
determining the hearing capabilities of animals. The
animals are trained to respond to the sound through
several practices like providing them with food, water e.
T. C whenever they react to such audio frequencies.
