Conducting the Test
Press the black right/left button to turn on the
MA1. Use this same button to select the right (red
LED) or left (blue LED) ear. Press the up or down
arrow keys to select 20dBHL. Next press the 1 kHZ
button to present the tone at 1kHZ to the patient.
The tone will be presented as long as the
corresponding frequency key (i.e .5, 1, 2, or 4 kHZ)
is held down. If the patient does not respond to
the tone, increase the tone by 5dB using the up
arrow key and present again. Continue to increase
the tone by 5dB until the patient responds. Once
the patient responds, lower the tone by 10dB until
he/she does not respond. Continue in this “down
10dB/up 5dB” pattern until a threshold is
established, or screening protocol has been met.
Continue the same procedure for the other
frequencies. Record all results on the audiogram
card provided.
Note: Most states define a normal hearing level for
a pure-tone screening as 20dBHL. However, it is
highly recommended that you check with your
state health department, the American –Speech-
Language-Hearing Association (ASHA), or the
American Academy of Audiology (AAA) for specific
guidelines.
NOTE: An automatic power shutoff occurs after
30 seconds of inactivity with the audiometer to
conserve battery life. To turn the audiometer
back on, press the black Right/Left button located
toward the top of the MA1.
