1.5 Description
1.5.1 General
1.5.2 Air Conduction Testing
Hearing threshold levels can be determined by presenting test signals to the test subject
with the included headphones (Air Conduction –AC). The purpose of AC audiometry is
to establish the hearing sensitivity at various frequencies. The test can specify the AC
loss but cannot distinguish between a conductive versus a sensorineural abnormality.

1.5.3 Bone Conduction Testing
Hearing threshold levels can be determined by presenting test signals to the test subject
with the included bone conductor (Bone Conduction –BC). The purpose of BC
audiometry is to establish the hearing sensitivity at various frequencies. The test can
specify the BC loss in combination with AC loss it can distinguish between conductive
versus a sensorineural abnormality.
1.5.4 Speech Audiometry
Speech recognition screening incorporates the child listening to a series of words at
different decibel levels and point to the picture. The purpose of speech audiometry is to
establish an ear specific hearing level when standard pure tone testing cannot be
performed. The level at which a patient can understand spoken language can be a valuable
screening tool, especially with young children. This speech recognition level can be
determined easily by the MA 33.
1.5.5 Masking
Masking is required if there is a notable threshold difference between the left and right
ears. It is possible for sound to be transmitted to both ears via bone conduction while
testing the poorer ear. This is called “crossover”.
Crossover occurs often while testing bone conduction, but it can also occur during air
conduction testing. Relevant to crossover is the sound level received by the opposite ear.
The difference between the original test signal in the test ear and the received signal in
the opposite ear is called “interaural attenuation”.
For Bone Conduction measurements the interaural attenuation is 0 dB to 15 dB. Bone
Conduction crossover is therefore possible even with a slight difference in hearing loss
between ears.

required for infection control at the facility.
If there is nota high infection potential, MAICO recommends:
•Before cleaning always switch off and disconnect the device from power supply
(USB).
•For cleaning use a lightly dampened cloth with soap water solution.
•Disinfect the plastic housing of the MA 33 and its accessories by wiping the
surfaces with wet disinfection wipes. Follow the instructions on the specific
disinfection product.

immediately to report it. Do not attempt to use any component or device that
appears to be damaged.
Reporting Imperfections
Notify the carrierimmediately if anymechanical damage isnoted.This will insure that aproper
claim is made. Save all packaging material so the claim adjuster can inspect it as well.
Report Immediately any Faults
Any missing part or malfunction should be reported immediately to the supplier of the
device together with the invoice, serial number, and a detailed report of the problem.
Keep Packaging for Future Shipment
Save all the original packing material and the shipping container so the device can be
properly packed if it needs to be returned for service or calibration (see Section 3.2).
