Thank you for choosing a GIMA tuning fork. The absolute
accuracy of the sounds is guaranteed by the special alloy
the device is made of.
PRESCRIPTIONS
The product is intended for use only by appropriately
trained and specialised medical personnel. The GIMA tuning fork
is very easy to use, and by taking just a few precautions it can be
used for many years
FEATURES
The GIMA tuning fork is used for a variety of hearing
tests (Rinnie test, Weber test, etc.), which test sound eld
sensitivity transmitted to the ear both by air conduction
(AC) and bone conduction (BC).
Conduc-
Description Parts of the apparatus
tion
AC An acoustic
stimulus is sent
to the ear by air.
BC This is carried out
by placing the
tuning fork stem
in contact with
the patient’s head;
the vibration caused
by the instrument
directly stimulates
the inner ear.
in which hearing
defects can be found
External auditory
canal, middle or inner
ear, auditory nerve
or central auditory
pathways.
Inner ear, auditory
nerve, central auditory

OPERATION
The frequency is changed by sliding weights on the
prongs. These weights can be adjusted easily by hand.
When selecting a tone, ensure that the weight spring
is engaged in the tuning fork groove. This is the only
way to obtain an accurate frequency. The two weights
must always be set at the same height. It is therefore
not possible to create intermediate tones by setting a
weight on a tone that is dierent from the other. The
letter printed directly below the weight indicates the
tone produced. If possible, the tuning fork should be
struck on the palm of the hand or on a piece of wood or
plastic, never on an object that is too hard (such as sheet
metal, steel or stone). The blow needs to be quick and
strong; in other words, the turning fork must touch the
object only briey.
The oscillation period of the tone will reach its maximum
duration as a result of this short blow. During an
examination (sensitivity test, etc.) the tuning fork is
placed with the base of the black foot piece on the
patient’s areas to be examined after striking them
Tuning forks cannot be sterilised after use. The tuning
fork should be cleaned using a dry or slightly oily cloth.
TRANSPORT AND STORAGE
When packed for transport and storage, the device
can be exposed to environmental conditions in the
following ranges:
1. Ambient temperature from -40°C to +70°C
2. Relative humidity from 10% to 100%, including
condensation.
3. Atmospheric pressure from 500 to 1060 hPa.
For a correct hearing test, active cooperation from the
patient is required. In fact, the measurements made with
the tuning fork are based on the patient’s own response
during the test.
The tuning fork complies with the Lucae standard and
produces 7 dierent frequencies, from c 128 to h 240.
The accurate frequencies can be obtained from the
tables below.
